So I was wondering about the truth behind the risks of frying your cpu through overclocking or the chip itself degrading faster over time, and if there are such risks do they apply to a simple 2.5 ghz overclocking ?
There isn't any risk like that, unless you are using extremely high voltage, or are at terribly hot place.
I have tested all the overclockable kernels, and haven't found a single one which is steady at 2.6 or 2.8 GHz. Only Faux's kernel at 2490 MHz is stable.
Don't be scared, there's no risk.
PS: I personally use Performance governor by the way, so the CPU is always at max frequency, against all advice I keep using that for past three years, never had a problem, and you can understand where I live the temperature reaches extremely high in summer, so...

That's actually comforting I too am using fauxclock and I live in Egypt so the temperature gets pretty high here, but I'm constantly monitoring the cpu's temperature so I will give the 2.5 ghz overclock a try for a while and see how it goes.

Yeah do that. Just to see if the OC is stable run that damn Antutu benchmark. If the device doesn't reboot/stuck then OC is stable
Best of luck.

Ha ha. Good. That's on Faux right? I got almost same score (44.7k) when I was checking.
Now if you want more then flash one of those 2.6 or 2.8 GHz kernels, and do the test, and message me if Antutu finishes the benchmark even once

If you want higher you should try out Ultimate Kernel. Although it is removed from XDA, you can still find it on some foreign language site. It's the highest and most stable OC kernel I have used (3.0GHz).

Thanks a lot for the link mate. Downloaded and flashed v73, but I can't get it past the stock clock rate of 2265 MHz! I mean I have tried to set higher frequency than that in S Tweaks, even downloaded Trickstar, SetCPU, but the it'd just stuck at 2265 MHz! I can go lower than 2265 but not higher! Weird!

I think it comes with 2 apps for customization. You apply frequency on the first one and open the other and select apply changes. I'm not sure if it was this kernel or was it AEL. Lol. Anyways good luck. Maybe your ROM doesn't support a certain "stuff". I'm sorry but I really forgot about those terminologies. You can read up on the closed thread if you want. I'm sure you'll have a clue or on that link I gave you. *Google Translate ftw*

Releasing my kernel ver10 which has NO OVERCLOCKING but has Undervolting. I'm pretty happy with the speed of Tegra 2 and I think there are a few advantages in keeping our speed in stock. Advantages IMO are as follows
1. Better Battery life
2. Less heat
3. Stability (unless it is too undervolted)

** If you get a scaling_governor error upon starting PimpmyGtab. It means you need to set your governor by going to Terminal and typing echo powersave > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor or by installing CPU Master and choosing powersave in governor.
BIG THANKS TO CPASJUSTE for the app and kernel codes.
BTW, If you like my work, don't hesitate to buy me a beer
If you ike PimpMyGtab, make sure you buy PimpMyCPU (Source) from the market by Cpasjuste

Nice. I'm not a fan of overclocking, however undervolting DOES interest me. As soon as I get an opportunity, I may try this out.
Curious, what's the stock voltage?

stock - 750mv - 1000mv
Well I tried it out real quick, it works well (haven't verified battery life changes), but I had some questions:
Is there anyway to set the voltages explicitly? SetCPU didn't work with it (couldn't even change the freq or scaling governor).
I forgot your kernel doesn't support mounting the internal SD over USB. Is that something that will be fixed soon (assuming it's actually broken)?
I won't have my tab for a few weeks, sending it in for warranty replacement. So I won't be able to do further testing.
Thanks for the great work!
Hello clemsyn,
Try it out and battery life is soooooo gooood ... lot better than the OC 1.5GHZ one, of cause it run slower, but it's where i came to ask, if you could release one with the same voltage but for 1.2Ghz (which i guess it's stock speed)?
Many thanks for your hard work

Thanks. Right now I'm tryingout the 700-900. Quadrant dropped from 2350 to 2150 going from ver9 to the UV.
I've been using the original kernel posted in this thread for a little while now. It has some strange slowdowns when the tablet first boots (from being powered off), but after that it runs great. Have not had any freezes, so it seems stable. Quadrant scores are ~ 2300.

While the quadrant is down a little, I can't really tell any difference in performance when using the tablet. If the battery life improves then I will stick with this one.

Seems like your tegra can't take the underclocked settings.
Well that sucks
Hey everyone...I tell ya, I sure am enjoying all these awesome custom roms and kernels. Great job to all the developers here, putting in the blood, sweat, and tears for the advancement of the community, thank you so much. One feature that I saw in a Xoom build was the GPU overclocked, and while I'm sure it won't interest everyone, and there is probably only little gain to be had from it, I would love to have the option to oc the CPU and the GPU for the highest performance possible...please. Well I think that covers it unless someone else shares my desire to see this feature. Thanks for all your work and consideration XDA and have a great day.
if ur CPU OC than GPU too
Apparently not so on the Motorola Xoom as there are two versions of Tiamat 1.4.4... with and without GPU OC. Tiamat 1.4.4 Full Throttle

oc-ing the gpu doesnt get you anything... gpu is default 200mhz 2d with 300mhz in 3d and it can be uped to 250mhz 2d and 400mhz 3d but it cant be software controlled and it will eat more power...
and no oc-ing the cpu doesn't oc the gpu, its a separate part of the tegra2 processor
Hey Thor, thanks for joining the conversation. Based on what youve seen so far, how well are the tegra GPU cores being utilized? Suffice to say I've pulled off insane desktop GPU overclocks that showed almost nill gain with drivers that werent mature in which the GPU cores werent being loaded past 50% . I realize that the tegra is a horse of a different color, but isnt it still affected by the specific driver optimizations, hence the THD enhancements? Just out of curiosity as I very much trust your experience. I am still interested in trying it with definitive comparisons to follow...well about as definitive as synthetic benchmarks can be anyway.
I just saw that you have a new beta... Yay. I cant wait to give it a whirl.
I have been over locked for a little while. Max I have done is 1506 but it tends to be slightly unstable. I run 1400 now and haven't had any issues. biggest difference I notice is home screen transitions load fast and don't lag and programs load much quicker. there doesnt seem to be any games that will push the CPU hard so I don't notice much of a difference there.

I've had 1600mhz going strong with no instability, benchmark after benchmark, the only issue I've had is the device shutting down when left alone for too long, but I consider that a useful standard function. Otherwise 1600 performance has been rock solid. I decided to take it upon myself to take this girl apart' clean the CPU off, remove the thermal pad, and apply some as5....though the chip didnt really run very hot to begin with. Now until I have the option to go for 1800mhz, I'd like to see where the max threshold is for cpu/gpu oc.
I have mine overclocked also at 1600.. Runs very stable at this speed and benchmarks not too bad:

Thanks! Works great. Do you feel the HoneyVillian rom runs faster with the v2.4 Kernel or about the same as stock Acer 3.1 HC rom with v2.4 Kernel?
So far I can keep stable at 1.5 after 2 hours of use. It's also slept for 30 mins and seems ok at that too.
Also what kind of Scaling do you guys use? Ondeman, Interactive? On my phone I use ondemand.
I recently flashed the newest Trinity Kernel on my Nexus 7. I still have the stock ROM. I tried to tweak the CPU settings with ROM Toolbox and the most I can overclock is 1400mhz. Why can't I overclock to 1600? Is it because of the stock ROM? I'm looking into Glazed Jelly Bean as a custom ROM but I'm not sure I want or need to use a custom ROM at this point.
Any suggestions?
Because he dropped the Max. You probably flashed A111 correct? That's a TSVZ meaning it is slightly over clocked and undervolted kernel meant for battery not for performance.

Nice, ill have to look into rooting sometime soon.
Ok, I got the a96 and I've flashed it...
Is there a detailed changelog for each version? The a111 said it was a 1600mhz kernel so I don't understand why it was dropped down to 1400. That's where my confusion was.
I did notice some increase in speed at 1400. I was having some stuttering issues with Dead Trigger and Minecraft PE, and they were less with the 1400. I've got it running at 1600 now but I don't know what it will do to the battery or how well it will perform. I'll find out later. I've run through the battery pretty quickly today, but I was tinkering with it A LOT so it's not accurate.
What kind of tweaks could I do using Rom Toolbox that would help me maximize my battery while overclocking to 1.6?
Dont over clock.. i dont even see a need to. I use the ondemand gov which stutters a little but using interactive clears that up. Also using the CFQ IO as it is the stock IO used. Its stock so its gotta be good . Also you should turn F-Sync off that helps quite a bit. Also you could toggle auto hotplug and make it only run two cores while gaming and then turn it back on when finished so that way it will hotplug cores as it sees necessary. You could also up the voltages a little bit, some CPU's dont like the lower voltage and that will cause stuttering and glitching just up them by 25mV and see if it clears if not try another 25mV.
I will try those things, but I really want to play with overclocking and learn what happens. This is my first Android device so I'm experimenting and playing around.
But I have one more question...I've overclocked to 1.5...I found 1.6 to be the same as 1.5. But it seems that after an hour or so, it resets to 1.3. in ROMToolbox. Why is this?
Don't use rom toolbox. Use the Trinity app. It sticks just fine for me. Besides you support the dev to make better kernels.

youre not the first
Overclocking past 1.4 Ghz doesn't result in any major usability improvements. I've gone up to 1.7 Ghz and the only thing it does is make my tablet really warm and unstable. All you really need for improving system performance is I/O tweaks to speed up app and page loading, and a little bit of GPU overclocking to help with the transitional effects.
and, to be honest, depending which trinity kernel im using, im using either 1100 or 1150mhz mostly. on a111 im using 1100mhz and on a96 i used 1150mhz. with those speeds everything is still fast but a bit better on battery
Overclocking

Why would you need to overclock so high? Do you want it to explode! xD
Seriously though, would probably advise against it. It's like a whole 700/800 MHz higher than it's meant to run at stock. I'd say it would be very unstable, and probably wouldn't get very far battery-life-wise. 1.6GHz really not enough :/

1.6ghz is ok? or i'll risk something?
I did that speed already. But it is very very unstable. random reboots within 10 minutes of use. also the battery life is very low. and the whole tablet is to hot.
i only was using it to see how fast it could go. that was the max. i am at Cutom Rom - 07/10/2012 - [email protected] Edition V02 - The Ultra Fast Rom - based on last Asus Firmware 10.4.2.13 at this moment.
this is very stable. balanced speed is 1.3 and thats oke. Normal performance speed is 1.6 but i only use that when playing games. You dont need those high speeds for daily use.
If you have the financial means to buy a new tablet - you can try all the time to work on this frequency.
With 1,6ghz i'll risk to break the tablet?
i used 2.0ghz about a week daily use. But now im lowered it to 1.8ghz and it is stable my everyday use. and battery lenght is very good maybe better than stock (i made undervoltage, so cpu uses -50mv less power in any speed than normaly/stock )1.8ghz use 1150mv and lowest speed use 775 mv)

well, if you raise voltage up it may help, but i thing the problem is, that every tablet cpu is "diffrent" than other. This i mean, that these cpu is specsed in other speed than 1.6, 1,8 or 2.0ghz, and some invidiuals might work good in these higher speeds, some get randon reboots / freeze, or some of cpu:s dont even boot higher speeds. (i found out that when few people test my kernel, and it not even booted. And someone it will work fine.) This thing can "cross" by made kernel force cpu speed 1.0ghz at bootup (and i made this my kernel)
Also these tf300 tablet is manufactured atleast couple of diffrent cpu type /cpu id, so kernel have to had support all of these overclocking
It just like computers, some cpu can overclock higher than others, and if you go too high you need extra cooling, and in tablets, it is not possible, like normal pc's
*Most of this is my conclusion only, it may not be 100% accurate truth, but this how i see this thing. And if someone knows better etc, you can correct me *

*Most of this is my conclusion only, it may not be 100% accurate truth, but this how i see this thing. And if someone knows better etc, you can correct me *

Well im not home right now, so i dont have any 2.0ghz or 1,8ghz kernel with me, i have only 1.7ghz oc kernel, so you can test it if you want. But just like always, im not taking any responsibility, so test /use it with own risk. https://www.dropbox.com/s/vvmti4knwkeflde/Nixu_Kernel_OC_1700_v0.1_alpha.zip
i'm afraid now loool, what would happen exactly?
after flashing the kernel is locked to the screen asus, does not want to start
That won't happen I flashed it

Hi,
I've noticed a huge performance difference between kernels and the roms they're used with.
For example:
I was using AOKP and Franco kernel and got around 20000 antutu points, I've switched to Carbon Rom (because of the build in pie control) and Franco kernel and only get around 13000 points, that's a huge difference.
As a test I've installed Matr1x-kenel on Carbon and get around 21000 points.
I really like Franco-kernel and all the tweaks it offers but don't like the huge drop in benchmarks, I know benchmarks are not a real representation of actual performance but it's still a big difference.
This also occurs in Quadrant and Geekbench.
So my question is why does this happen?
Aren't most roms supposed to be compatible with most kernels?
Thank you in advance.
Best regards.
I can't answer your question as to why that happens (no doubt someone else will) but you seriously should just stop bothering with benchmarks and use your own eyes and experiences as a measure of how good a kernel/ROM is. I doubt you could find a kernel which made the phone visibly slow or that affected usability so I don't see what your concern is tbh.
Thanks for your answer.
Yeah, I read that a lot on XDA, don't trust benchmarks...I understand that but they must have some meaning.
I mean, if not why do they exist or do people bother using them?
To be honest I don't really notice any real performance difference between most kernels I've tested.
Best regards
some roms include many optimizations(like skia/dalvik, krait optimizations, and others), while some dont. its not thekernel thats crapping out on you, its the rom.

your eyes can be decieved.. they can see whats happening in the ui for example, but you can not see the complex calculations that are being performed or how your cpu is really performing. you can have a slow device whos ui is quick.
OK, I can understand that not all roms are equal but why does changing the kernel have such a seamingly big impact?
If a rom is bad to begin with it should stay that way no matter what kernel you use with it.
Offcourse what do I know, I'm not a developer so my knowledge on the subject is limited.
I'm just trying to understand what's going on...
Best regards

kernels vary too, and they impact greatly because they control just about everything in the phone, kinda like a brain. since the kernels themselves vary, one kernel might be better set up than another to deal with certain code from a certain rom. and then also, every phone reacts differently to each kernel(and roms to a point). thats why its recommended to try out different kernels, combos. only then you can find the perfect combo for you/your device. what works great for somebody, can be lousy for another.
OK, so if i understand correctly it boils down to this:
1. You can do benchmarks but don't base your opinion on just the benchmark scores.
2. Roms can vary greatly in optimizations and efficiency of coding.
3. Kernels can also vary greatly in optimizations and efficiency of coding.
4. There's no such thing as a "best for everyone rom/kernel combo".
5. Not all roms/kernels play equally nice with each other.
6. Play around with as many roms / kernels as possible and decide what works best for ME based on MY experience.
Thanks for the advice.
Best regards.
Its been well over a year since I ran any benchmark of any sort but I tested Franco and carbon because that's what I'm on and you mentioned low scores. I'm on Franco m3 with some tweaked settings and carbon nightly from 7-5. Antutu gave me 20636. I'm using stock CPU and GPU frequencies.

Maybe the nightly Carbon rom is more optimized?
I'm on Carbon 1.7 Stable and used Franco nightly 162 to test with.
When I benchmark I try to be as consistent as possible ie same temperature, performance governor, airplane mode etc.
I even cooled my Nexus in the freezer for some minutes to eliminate thermal throttling (yeah I know, watchout for condensation) but still got the same low scores.
Best regards.

It might be, I didn't do anything special. I left all my background apps running, didnt close anything in the recents, didn't cool the phone first. I just downloaded it and hit start. I use the interactive governor tweaked a bit, and I also tweaked the hotplug settings so it more readily onlines all 4 cores instead of waiting for some of the higher loads to trigger it.

Well, I had to try it myself so I did a factory reset, cleared system,data and dalvik, installed latest carbon nightly.
With stock kernel I almost reached 21000 points, with franco I barely get 17000 points.
Very strange...
edit:
I stand corrected, did a second benchmark and am now getting 20880 points...
are you benchmarking with your cpu speed benchmarked set as highest and lowest cpu speed? you should. if you dont put the same cpu speed as highest and lowest then itll scale up and down. if it scales, you dont actually know what speed its testing and it gives you inconsistamt scores. you want the cpu speed to be the same throughout the test.
When I benchmark I set the governor to performance, this should keep the cpu running at maximum speed without scaling unless I'm mistaking...

meh, performance is the worst for benchmarking. its such a deceiving name. try either ondemand or interactive. set your cpu speed to be the same high and low.

Woow, that's a great tip, I now get 22003 points with Matr1x-kernel.
