OpenCL: Can we mine Litecoins/bitcoins with Nexus10? - Nexus 10 Q&A, Help & Troubleshooting

I just recently tried litecoin mining on my laptop, but using 4 threads it brought my CPU up to 85C which is also the "critical" high temperature.
I have a core i3-2350M, [intel hd 3000, apparently no OpenCL support] and Ubuntu. Anyway I have a Nexus 10 and discovered it apparently has OpenCL support: http://beyond3d.com/showthread.php?t=63071 http://malideveloper.arm.com/develop-for-mali/sdks/mali-opencl-sdk/
Now could anyone tell us if it is possible to use minerd or cgminer to mine either litecoins or bitcoins [whichever would be more efficient] with the Nexus 10 harnessing the GPU power with OpenCL to create a low power [10W max charger output] small mining rig?
If it is possible, someone please point me in the right direction!
If nobody answers here, perhaps I should ask in Litecoin forum.

As powerful as the Mali GPU is, it wouldn't compare to a desktop mining rig with a proper mining card. Not worth the trouble.

Well the point is, I don't have a powerful mining rig, BUT I do have a Nexus 10. I am curious and would at least just to try and see how many KH/s I can get. I just want to try it while measuring the wattage, then I can decide if it's worth it or not.

If you can run Linux on the N10, you can possibly bitmine too, given that the OpenCL drivers exist, work right, and can be accessed from Linux (which I believe runs on-top of or side-by-side of Android, depending on the method).
I do believe you can run Linux and VNC into it or something from Android. Ubuntu Touch may also be an option, but not in its current state.

This doesn't exactly tell me how many kWh it will take to mine 1 LTC [at 1 LTC/5 kWh, I am barely making anything considering electric bill, at $0.15 kWh], so while the page is useful, not exactly what I was looking for. Thanks though.

With so much information on google i wonder why you ask in this forum.. either way
your nexus 10 will get maybe 5kH/s . Solomining is out of question. So joining a pool which is what would be recommended to you ( after lots of laughter at your nexus 10 mining attempt ) you would have a 2% fee on anything you mine. With a difficulty of 437.9378214. Running your N10 24/7 you would mine about 4.24 LTC/year this is obviously if your Nexus 10 survived a couple days of straight mining at the most.
Good luck and kiss your 10 goodbye first.
P.S instead of burning your nexus 10 with the mining attempt and having to buy a new nexus 10.. Why not take that money and buy some coins while they are low. Litecoin went from 1.5 to 4$ over a month.. expected to reach 10$ at the least by years end... Just a thought.

Your 5 KH/s estimate is pretty far off. With an ARM-optimized version of cpuminer, I'm getting 1.1 Mhash/s with an Optimus 2X on the CPU.
In addition, the Nexus 10 scores similarly on GLBenchmark as the Radeon 5450, which mines at around 10 Mhash/s. If someone bothers to implement it, we could expect around 5-8 Mhash/s at least.
I'm researching the possibility of GPU mining on the Nexus 4 and Nexus 10 for my miner app.

If you do eventually implement this in your app, let us know on this thread.

I can almost guarantee that you run the risk of melting your battery doing this (and potentially catching fire). And considering the size of the Nexus 10 Li-Po battery, I share this sentiment with utmost concern.
If you're going to do this, I strongly suggest you run it while locking the GPU and CPU to no more than 50% of their max capacities, or whichever doesn't make the temperature go bonkers (maybe 50C max??).
Good luck!

http://androidcommunity.com/asus-ee...ice-cream-sandwich-expected-in-q3q4-20110623/
It should never be too early to talk about the next TF that is coming later in the year.
I have the original & I love it but I'm not sure if I will be getting the TF2 or not. If they keep the same price range then it will be hard to resist in getting one. I just recent got a brand new Euro GSM GT 7" for the hell of it & I like the size. I'll probably look for a tablet in the 7-8" range & give my mom my TF since she uses it more than me.
So will you be getting the new TF2 when it comes later in the year or will you be going a different route?
A lot can happen between now and October, when he TF2 is anticipated to be out. I doubt that I'll be ready to replace the TF so soon, and I'm guessing there will be a pretty exciting new round of products coming out in 2012. So, I'd be more inclined to stick with what's working well for me, and see what's announced at CES 2012.
If I had the funds to upgrade my gadgets every six months, I would. Alas, I don't.
Sent from my Transformer TF101 using Tapatalk
It will depend on how better the TF2 will be.
I'm usually a sucker for the latest tech and a Kal-El processor is definitely hard to resist.
But I hope its just more than spec bumps, a lighter, slimmer form factor with better speakers would be nice.
If it turns out to be good then I'll probably sell my TF and get it.
Ditto, depending on how much of an upgrade the TF2 from the original TF is what will make that decision for me. Also the $ aspect
Ice Cream Sandwhich will also be a big factor, Im excited to see what it offers over Honeycomb.
Like everyone else, I may consider it, but I don't have a job, so it may be hard to get the funds, especially since I need the keyboard dock for school, and I don't even have that yet.

Lol...i know i'm trying to wait for it to go down a bit...not saying its not worth 150, cause it really is for all it does....idk, im thinking next year i'll look and see whats out there. The good thing about the TF is that it was a good price, and usually that pushes the prices of the competition down, so in a few months we might start seeing more tablets in this price range...
There is absolutely NO NEED for a quad core processor in a Tablet. This will just eat battery life ( unless they change that as well ) and cause it to get hotter.
Quad Processors are for MEDIA and GAMING machines. Machines that will take advantage and USE them properly. Tablets? No need.
If that is the only change between the two devices then anyone that does get one.....Well you know the saying " A fool and his money are soon parted ".

The more cores doesn't mean the more power it uses, In fact the new Kal-El chips will have less power consumption than Tegra 2 at the same clock rate.
Apps also aren't the only thing that will benefit quad core processors. General tasks such as browsing or watching HD movies will benefit greatly.

Because 4 cores processing the same workload is more efficient than two cores doing the same job.

Correct, as the work is shared and spread at lower amounts between the 4 cores.
At this point, I can't see anything that will get me to upgrade. Everything I need can be done on the Transformer - it's fast enough for me, games run great (I play games that run well on my old Android phone, so quad-processor Tegra 3 isn't needed..... ). I don't know of any features I "need" that I don't already have with this tablet.
Of course, my phone does need to be upgraded.... but that's a story for another day LOL

4 cores = no more lag on the browser???? Wow, sign me up....
How about they support this one with accessories? I would love to hear about that more than making a new one and **** the original. An over priced and poor quality case is the only real accessory they have.

Future iterations of the ASUS Transformer line are said to be compatible with the current keyboard dock accessory. If you want to upgrade your TF, just replace the tablet itself and the new one will fit right in the keyboard dock. Saves you $150.

Understand and agree. But, stop a minute. What tasks do we all do that would truly (now, be as objective as we can lol) necessitate a quad core processor on a tablet? Who here is doing large spreadsheets? Ripping, re-coding mpeg2 files, etc. I can't speak to games as I don't play them so I'll not comment. Other than note taking, email, YouTube, a movie here or there, web browsing, Pulse, etc all mentioned perform (for me at least) quite well on the Tegra 2.
I love the "latest and greatest" too. And I consider myself very fortunate to not have a TF plagued with build issues others are experiencing. But, for me, until I see full specs that include the TF2 giving massages (oops, I take that back!) I'll just zip along with what I have. "Needs" and "Wants" are vastly different and seldom the same. IMHO.
Now the Devs, well they're different breed of cat. Heck, they've probably forgotten more about android than I'll ever know! A quad might well be indicated for them.....but the the rest of us?

I'm inclined to feel the same. I love the pace of current technology innovation, but I can't stand how the race to get to the next product launch consistently leaves products from the previous generation with serious bugs and other unresolved issues. The GTab is a good example of that...thank God for the dev community, who saved that device from the ashes.
The sooner Asus releases the source code, the better we'll be able to take care of ourselves in the long run with this device.

This would be cool if it ends up happening (and I'd definitely upgrade if that were the case), but the TF 2 is rumored to be thinner than the TF. Not sure how it could work with the keyboard dock if that's the case.

Do not the software/apps have to be written to take advantage of quad cores? My guess would be a quad core tablet would kind of be a waste as at least 2 out of the 4 cores would sit by doing nothing most of the time until all the programmers catch up.

why does my wife iPad Mini play games so much better than my Nexus 10

I downloaded the new D Day game on my Nexus 10 and the iPad Mini. Why does the game to play so much faster so much smoother so much better on the mini rather than my Nexus 10? How can the mini that has such Lower specs play it so much better and this is what other games also I'm running stock rom with custom kernel. I really want you like my Nexus can but if the mini or anything else plays games better and may have to switch what can I do to see if substantial difference in this. any advice, tweaks, tips would be greatly appreciated thank you
Short answer: Developers are lazy
Long answer: The iPad Mini is pushing a lower-resolution and thus, 3D applications don't put as much strain on available graphics resources. The Nexus 10 is pushing 2560x1600, which is pretty aggressive, and developers need to fine-tune their apps, as to not choke the available bandwidth. Most developers just simply lower the internal game resolution, but this may not be enough depending on other factors.
Other factors might include, since iOS is only available to a few devices, and Android covering, a lot more, the developer may of either chosen to test the game on only one device not-related to the Nexus 10, and may not even be aware of it having performance issues on the Nexus 10 (in which case, you should alert the developer at some point).

Thank you for your reply...that makes sense to me...will the devs ever really catch up with this ? I just wonder since its the highest resolution tablet yet. I just installed carbon room and I'm very happy with the general ui speed now, I'm going to try a few games also with it to see if there is any difference...
Are there any settings in the Dev options that I need to change to help also?
Thanks again
Edit...I just tried that new dday game again and still very laggy....yuck..
Some people recommend enabling 4xMSAA for OpenGLES 2.0 apps (named something like that anyway). Another popular option is to enable Forced 2D GPU acceleration.
A lot of games start off on the iOS platform. Then it seems they will do the bare minimum to port it over to android.

You'd think right? But honestly, having a ridiculous number of manufacturers, with different hardware on different versions probably scares a lot of developers away. Its much easier to make a game for a single piece of hardware and os.
[Rant]I love how android is open source but in the future I hope they at least set some standards for hardware to help unify android and prevent these crappy companies slapping together leftover hardware and throwing on whatever android os will run. [/rant]
The dev is probably lazy. Epic Citadel, one of the most demanding games, run at 54fps on the Nexus 10 at full quality. I wonder how the iPad mini will handle it, but I'm highlighting my developer-is-lazy point.
Ipad minis form screen size factor its simply perfect . light and premium materials makes it an incredible device . but the deal braker its the IOS .
I ve had a ipad mini on my hands 3 days . battery holds 12 hours with average use .
The PERFECT TABLET IN THE UNIVERSE would be ->
IPAD MINI WITH ANDROID , TEGRA 4 AND SAMSUNG CPU !!

With the correct Governor/Scheduler/ROM/software tweaks it can be as good/even better than the Ipad. As I have mentioned before, my wife has an Ipad 4 and I find her snatching up my n10 if I put it down around her. She is an Apple fan-girl but she definitely sees the appeal of android, and she loves my Nexus 10. I will be the first to admit that Real Racing 3 gets higher framerates on her Ipad 4 but it is still smooth on my Nexus 10 and isn't much of a surprise seeing as it was developed on iOS originally and is just a port.
EDIT: I am using the MAX graphics mod with RR3 so the graphics are identical to the Ipad 4.
A tegra 4 and a samsung cpu? Confused...
Also I hate the ipad 4x3 aspect ratio...
My perfect tab would be the nexus 10 with the exynos 5 octa... And a samoLED screen with the 5250x1600 res and Wacom digitizer
The problem its that the mini iPad has higher frame rate than my nexus 10 also ... Not the iPad 4
The aspect ratio on iPad mini its perfect . its very light . nexus 10 its a brick compare to that . that its a portable device ...
Tegra 4 or a a GPU powerful like with an Samsung CPU and an aluminum case ... Nexus 10 case its like a old granny chair ... Squeaky, crackle ...

can you share your settings for the best performance? i am on Francos kernal if that helps also..
i would LOVE to tweak my N10 to the max before i make my decision on which to keep
Try out Trinity Kernel instead, it is far better performing now than Franco's. It has the best stock performance at the moment without changing any settings around.
Or you can try the KTManta kernel and use the Ktoonservative governor with these settings:
cpu boost level - 800
gpu boost level - 533
boost cycles - 7
disable hotplugging - 1
sample time - 30000
sample time with screen off - 90000
down threshold - 30
hotplug down - 29
up threshold - 75
up hotplug - 80
And then make sure you have force 2D GPU in the developer options turned on.
Any scheduler should be fine, but I have seen that Zen gives both good read and write speed.
If you do some undervolting you can get a lot better battery life too. Just remember that the GPU needs to have its voltage set to a multiple of 25 for each step.

[Q] Close to the Nexus 11?

I can't post links since this is my first post, but I found a tablet called the Voyo A15 which uses the Samsung Exynos 5250 clocked at 2.0 GHz.
Has anyone seen one of these in real life? I was really excited when I heard the rumor of the Nexus 11, but that seems to have faded away. I really wanted a bigger screen (mostly for comic book reading), but no-one seems to be making 11.6 inch android tablets for sale in the USA. This has the same processor as the N10...has anyone here had any experience with Chinese tablets? It's readily available for about $290 shipped to the US...am I crazy for even considering it? Thanks for any insight you guys might have...

Is it shipping with a 840x480 resolution close to what most Chinese tablets (i've seen anyway) use? And is it really using a Samsung chip? Not, say, a "Samsug Exnos" chip or some bs? Does it throttle within seconds from 2.0GHz down to its real frequency?

Looks good on paper...and is really cheap. Might be good for a comic reader. There is an unboxing video of it where they say the cpu runs at a max of 2.0 GHz.Are there any other (non-Chinese made) 11.6 inch high res tablets coming out?
Don't buy anything from China. I gurentee you when you get the tablet it will say all those specs and mabey the screen will be HD, but the processor will probably be like a 1 core 800mhz or something with 512mb of ram.

Anyway, If it's comic book reading you want, the Nexus 10 is perfect, at least for me. I don't understand what difference one more inch on the screen will make, but I do know that reading comic books on the Nexus 10 screen is an amazing experience.

I already read them on a 10 inch screen (Toshiba Thrive) but I find the pages are a little smaller than actual size, and I guess my eyes are going as I age, lol! I actually wanted them to be a little bigger than actual size, without scrolling...otherwise I would already have the N10.
I would like to see a refreshed Nexus 10 with a new design. Should let Sony design it this time. Their Xperia Z line is beautiful.

Didn't say it was perfect Just beautifully designed. Throw in a hi-res Samsung screen and we're good to go.
I wasn't aware of any non-Samsung devices being able to use Samsung's chips? I mean I'm sure Samsung could allow it; I just never heard of them doing so...

It looks legit...how bad could this be, lol! Are there any higher quality 11.6 tablets out there?
That site is legit. Send them an email to confirm the specs. They have pretty good customer service.

The tablet is legit, its just that are tiny bugs in Chinese hardware that bug you to no end. (Poor WiFi strength, screen angles, app compatibility even with basics like YouTube) Id advise against it. Buy a Windows 8 tab with Haswell if you're looking for bigger sizes.

Sorta kinda. Samsung is a major supplier for any number of parts (from screens to silicon), but the chipsets actually driving iOS devices are customized builds by Apple. Samsung is, at least in regards to apple in charge of the fabrication, not the design.

I also agree, but I really don't want a windows tablet. Honestly, now that I started questioning this, I am finding myself more curious. I guess if it sucks, it wouldn't be the first $300 I have wasted on disappointing tech. I'm this close to getting anyway, even though I realize it might be a mistake...but what if it as good as it seems, lol? Man, why do I agonize over stuff like this...

Is the Shield Tablet still worth buying?

I've been considering new tablets, and honestly the Shield Tablet has the features I want and I'm able to get one for $250, which seems reasonable. But I'm just wondering if it's still worth it as the it is a year old. How does it compare to newer devices?
If you're primarily going to be using it for gaming, there isn't a better tablet out there. The tablet is a steal for $250. The latest official update really makes the tablet shine and the custom rom called "Blisspop" even makes the device that much better in terms of performance. You won't regret getting one.
Well at the moment there are not many tablets that are faster (maybe even no faster) than this tablet.
Antutu scores are one of the highest even compared with the latest phones.
So speedwise it is still top notch and tablets that maybe come close you have to pay double the price for compared to a shield.
The 32Gb with Lte is unbeaten for that price.
I bought the 32GB LTE version in July, because an LTE tablet anywhere close to the Shield in terms of specs/screen etc. would have been ~$150 more.
Despite the battery recall issue, I'm satisfied with it. My (original) unit has been working perfectly and is very smooth with Lillipop 5.1 (the 3.1 OTA).
I should be receiving my replacement tomorrow, according to UPS. Presuming it doesn't have a defect, I'm looking forward to settling in. I never bothered to settle in on the old tablet (automatic actions, power saving stuff, that kind of thing) since I found out about the recall shortly after buying it, and didn't bother to fine tune it.
I recommend the tablet as an LTE device in the US, though if I didn't need the LTE connectivity probably there might be better values in wifi only (I'm not a gamer, so other tablets could meet my needs... but there are relatively few 8" LTE tablets without permanently locked bootloaders here).

The problem of the tablet is really the processor that is getting old pretty quick (don't know exactly it's true performance), but nowadays everything coming out is already being 8 cores at 2 ghz or more.
Keep Cool
But they are often not faster. Gpu of the shield is very fast maybe the fastest around at the moment. The SOC is still one of the fastest around and it is just on the market for 1 year so not that old.

Where can you even buy one of these? In Canada every single place is sold out and saying they won't stock them again. The used market can't find for under $500 either.

No. It's just that there are none...
There seem to be two of them for sale at that link when I go to it. One for $290, one for $320, both advertised as new (resale). Probably you're just filtering by Canadian sellers, based on your picture. Lots of folks in US won't ship outside the US, so no big deal that they aren't showing up for you.
Best of luck finding one!

Yeah my question was basically how to get one to Canada that's under $500. Impossible! Cheapest I've found is on eBay shipped for $530 for 16gb model no accessories.

The thing is that there aren't much AAA games to play in the shield, it's a good device more for the extra nvidia stuff.
I'm waiting for Borderlands 2 for a damn long time, but it never comes, and I don't even know if it runs on the device with good performance or if it's just for the Shield TV.
More impressive are some cheap windows tablets that for around 350€ can even run Battlefield 3 on low to mid.
Now with DX12 and tons of compatibility tablets might go more for windows again.
In fact I'm not liking much android, not a single game like the good old C&C Red alert 2, boot takes almost 2 times longer than my wind 10 PC, some websites stop working, multitasking is a joke since we can't even play a youtube music while doing anything else...
ps: Also in most performance tests we see other tablets ahead of Shield, so I don't think anything is actually that much optimized for it, not even most tegra games.
Keep Cool
My Shield Tablet LTE topped my Nexus 9's scores on Antutu plus the Shield gaming is great to have. Let's not forget about the SD slot and the mini HDMI port on top either. This tablet still destroys everything else (even most phones) a year later. I really mine because it has a stylus and no dumb Samsung home button like their Tablet S/S2 does. Its hard to find a good tablet these days yet the Shield holds its ground and doesn't seem to lose any performance over time. I like playing Half Life 2 on it or DOOM 3 especially when I travel. Its nice to have a tablet which can play nice games too even though that's not its primary purpose for me.

Those cheap windows tablets also use Intel chips in most cases plus Windows an as OS handles things differently than Android does. I agree that there aren't many great games but the ones they do have are fun in my opinion. I have the Shield TV as well and I play all kinds of games including emulators without any issues. My i7 Samsung Ultra book probably can't handle some of the games the Shield can then again I haven't tried. I'm not a big PC gamer but I do know the GPU isn't that great in most Windows tablets/ultrabooks. Android M fixes a lot of the productivity issues and adds multi window and I'm sure Nvidia is working on it now anyway. They tend to lush updates out promptly in most cases unless there's a big issue.
I haven't seen another tablet have better gaming performance than he Shield or Nexus 9 since hwy share a GPU yet use different CPU's. My Nexus 6's SD805 doesn't come close to he 3D score that the tablet does but on Marshmallow it does get a nice ~1500 pt boost likely from the optimization in it. I can imagine the same will occur in the Shield Tablet but we won't know until Nvidia releases it.
I'm not saying the Shield is the best fit everyone but it is a great tablet if you are in the market for a LTE enabled 8in tablet thats fast, runs near stock Android and has nice games for it.
Most of those BEST Nvidia Shield games coming soon are old and I finished them already. (RES5, Half Life, Borderlands, Doom...).
The thing is, you get a good device, but you will probably end playing most games that your phone already can play maxed out.
Other thing is Nvidia blahblahblah says it's more powerful than a X360 GPU, but then most games have a little lag and nothing, but really nothing made to the android yet comes close to most X360\PS3 gameplay\physics (they just look good, but plays like crap).
Then it's my 4th Nvidia shield all are defective and the last one needs to go to RMA again.
I never had an android device, so I wanted to try it, with my experience is just a god damn bugged SO worst than windows.
Also I got sad with the strategy games and how nothing on the android thousand of games even come close to Command and Conquer Red Alert II from like 2000
My opinion:
GOOD:
- hardware Performance;
- Sound;
- has it's own wireless gamepad;
- Nvidia software + remote pc play (button mapping already in the tablet, no need to root 4 that);
- More games than other android devices;
BAD:
- Android is not really optimized;
- Not much AAA games:
- Nothing like C&C, age of empires, Skyrim........ (most games are very cheap copies of good games, but look like a 2003 game);
- In the real world, performance is not as big as nvidia make you think (best phones now probably have better performance, like Samsung S6 which is a lot more little and doesn't come close to having more than a hundred cores like this nvidia);
- Screen quality is not that awesome, it is a High resolution LCD, but nothing special besides that. It doesn't get any close to samsung phone's\tablet amoled screens;
- Battery doesn't last much either;
I actually think that something like that made for DX12 and wind 10 would probably get almost twice the performance than on the actual android OS. At least I saw some people playing BF3 on dell cheap 1 year old tablets that cost basically the same as this nvidia shield. Nowadays with DX12 and Wind 10 soon may be a new era for tablets (it seems windows based hardware have more performance per price than android devices). At least I never seen any 300€ android tablet playing anything close to a BF3 which is years ahead in gameplay + physics than any android game I ever seen\played until now.
ps: If it was today I would buy a ~350€ DELL wind tablet that can even play BF3 (guess what? No need to Root for anything as you own everything already and can update\mod everything).

NEXUS 9 RAM UPGRADE 16Gb (2GB) to 32Gb (4GB)!!

COMMUNITY IS ALL ABOUT SHARING, AND I HAVE SOME GREAT NEWS TO SHARE WITH MY FRIENDS HERE ON XDA!!​
I've have a 32GB Nexus 9 LTE for almost 2 years now, and she's been great, but, as most folks here will understand, I WANTED MORE RAM!! I picked up a Pixel C a month ago, and decided it was time to give the RAM upgrade a shot. Since I have the Pixel, if the worst happened during the upgrade attempt it wouldn't be the end of the world.
WELL, IT WORKED!!
I am working on a video tutorial, but wanted to share the good news with everyone!!
While I wouldn't describe my N9 as "laggy", it most definitely had it's bottleneck issues, especially on RAM intensive tasks like Chrome w/ multiple tabs open. Luckily, the LPDDR3 module is not stacked on the SoC in a SoP configuration . . THANK GOD TOO!! Because 2GB of RAM on a CPU this beastly is like putting a 100mph governor on an Indy Car. It took me a while, but I was FINALLY able to snag a 32Gb (514Mb x x64) single module (That's 4GB BTW). It's not that I couldn't find the right module; what held me back was waiting for Samsung to release the single module 64Gb (8GB) 253-Ball VFBGA LPDDR3. The Tegra K1 supports up to 8GB of LPDDR3 or DDR3L, but since the Nexus 9's board is built with support for a single VFBGA RAM module, you only have support for one. I got impatient and went with a 4GB module. The module is 1866MHz, but it runs at 1600MHz, so I don't think the K1 supports higher than 1600MHz (800MHz x 2), but I could be wrong. I didn't wanna push my luck with such an invasive upgrade, so I didn't look into pushing it to its rated 1866MHz. Besides, the stock module is 1600MHz anyway, and that's plenty fast for what I'm using my N9 for. I know it supports DDR3L, but I didn't wanna create compatibility insanity, so I played it safe, sticking with the exact same module brand (Elpida/Micron), type (LPDDR3), speed (800MHz x 2), and package size (VFBGA 253-Ball), but with a higher density (512Mb x x64 = 32Gb, or, 4GB). After removing the stock module, and careful placement and reflow, I was kinda surprised when I turned it on and it just worked. Not that I expected a problem, but y'all know how it goes. :fingers-crossed:
Props to Nvidia for an extremely flexible SoC. :good:
*(I will put the module details below if anyone wants to do what I did and upgrade their N9's RAM)*
After the upgrade, I decided to address the Tegra's heat issues. Long ago, I deduced that the cooling solution was lacking, if even there at all. So while I had her opened up, I spread some MX-4 between the SoC and an extremely thin copper square which acts as a heat-sink. Then I used a teeny-tiny vapor chamber heat pipe that was originally attached to a VRM cooler on a busted SuperMicro server board. After welding the heat pipe onto the copper plate, I cut out a small hole in the back cover and connected the condensing side of the heat pipe to a small, flat flat-finned VRM heat-sink. The heat pipe is obnoxiously long, so I had to get kinda creative with the spacing. I did consider using a teeny-tiny fan, but that seemed like overkill lol, not to mention the reduction in battery life. I made a small vented cover, but there is a noticeable bump on the rear cover, but with my case on it, and the fact that it's almost always on a stand, it hasn't been an issue.
Now, with a REAL cooling solution in place, I was able to use flar2's overclocking options on his kernel via his EX Kernel Manager app. With the CPU at 2.5GHz (up from 2.3GHz stock), and the GPU at 984MHz (up from 852MHz stock), along with several other tweaks, she has been AMAZING ever since, with zero lag, zero random reboots, etc. With fsync disabled, I consistently score between 120,000 and 130,000 on Antutu, depending on governor settings. I couldn't really push her prior to the cooling solution without some major throttling, but those days are OVER!! I don't know why Google/HTC didn't at least use SOMETHING as a cooling solution. Even a small thermal dissipation pad and a little piece of vented copper would've been more than enough to keep the throttling at bay. Not Nvidia's fault, I'm assuming their specs call for a specific Tcase for proper functionality, and I guess they didn't push her all that hard in the testing phase.
I'm working on a video tutorial & step by step guide for the RAM upgrade and the cooling solution, so if that's something you'd wanna do to your N9 (and if you're good with micro repair, I absolutely think you should do it!), I should have it up on the N9 forum by mid-week.
* The module I replaced the stock 16Gb (2GB) with is made by Micron/Elpida. The product number is:
- MT52L512M64D4PQ-107 WT -
There is another module with a VERY SIMILAR product number, with the same specs, but different BGA mounting & ball count: MT52L512M64D4GN-107 WT. I actually made this mistake and assumed the module was VFBGA, but it's actually WFVGA (256-Ball), and the voltage loop-back logic pads are NOT compatible with the N9's VFBGA module pads. Just stay away from any module that ends in 'GN' and you'll be alright.
I'm highly anticipating your video and this is absolutely fantastic news! I have 2 questions for you however since I'll be a little new on this installation:
1. Was the RAM module that was made from Samsung released? If yes is there a way to order it? I highly believe that with 8gb of LPDDR3 this tablet has a huge potential for future proofing and will eliminate the need to buy a tablet for a long long time.
2. Are there any specific tools or equipment I need to buy in order to follow your installation?
I'm highly looking forward to your reply and thank you so much for the upcoming guide.
Following....
Looking forward for that video.
I'm quite excited!!
4/8G on a tablet!!!
When is that 8G chip coming out?
https://www.avnet.com/shop/us/p/mt5...5626301278?CMP=EMA_Octopart_inventoryfeed_VSE right? Where did you get yours ?
I seriously doubt that 8gb would bring anything more comparing with 4gb. I think the main bottleneck is cpu architecture. It's very strange that 2 strong cores stutter more than some 8 core cpus. Nvidia doesn't have as large experience with cpus and has made mistakes, while it has largest exps with gpu.
Firstly, let me say, well done. :highfive:
Someone had to do it and you were brave enough to put your money on the line. Respect.
Any idea how you upgrade performs compared to a standard Nexus 9? It would be cool if you could get another and do a side by side test.
A part of me wishes you could have just upgraded the RAM and compared to a standard Nexus 9 as we will never know which of your upgrades has the biggest effect.
Just wanted to give everyone a quick update.
Work has been sucking up all of my time, but I have the day off tomorrow so I should be able to get the guide/tutorial up by the end of the weekend.
She's still running wonderfully, however I did decide to go the itty-bitty fan route just to see if there was a difference, and sure enough, I got my idle temp hovering around 30C - 35C, so I may add a step for an optional fan installation. I found a super slim battery pack and a 5V Raspberry Pi fan and it worked like a charm. I just need to figure out a way to tidy up the wiring.
Anyhoo, happy Saturday, and stay tuned!
Can we order these from somewhere? Everywhere i looked have zero in stock.
Looking forward for the video tutorial. While I do not have a tablet replacement for mine, I will still do this!
The thing I'm most worried about is flashing the firmware back to the new chip.
Things I think I'll need .
#1 A tool that can read and write to the chip so we can backup or restore.(those tools cost like 100$+)
#2 soldering iron or something to detach and reattach the chip.
PS. I'm really looking for that 8G ram chip.
I will need to compile a new kernel to support more than 4G but that's no problem.
This memory eMMC NAND Flash chip KLMCG8GEAC-B001-BGA-64GB seems to be similar to ours. Just curious will this one fits? :fingers-crossed:

I'm with you 100% on that . Let's assume the best in either case scenario.
It seems that it is not as easy as the author tells us.
And I doubt that he has something that works, or he did at least what he writes about.

But it would a dream, upgrading this tablet to 4g ram and 64 gb storage,.. Too good to be true...
