I know with the Galaxy Nexus, the GPU is normally clocked at 384MHz, but downclocked to 307MHz for battery/heat reduction purposes.
Is this also the case with the Nexus 7? The stock speed seems to be 416MHz, with Motley's kernel (for example) offering a 484MHz step.

So i've seen in internet that people who uses trinity kernel scores over 7k (in quadrant bench) @ 1.64ghz.And im with 1.7ghz and 700mhz gpu still get arround 6696~ [Got nexus 7 32gb 3g model]...So what's the problem?How can i increase scores?And improve overall performance?
Btw is there any software or something that could fix blown speakers ?

the gpu speed doesnt matter as quadrant doesnt test gpu. it looks at our fps, and our fps will be 60fps no matter how high your gpu is oc'd. lower your gpu speed as it increases how hot the device gets. are you using the trinity kernel toolbox app btw? at 1.7ghz i get around 6900-7200. make sure that you disable tegra hotplug and enable all four cores, for that extra bonus in your scores. and that you bench at 1700/1700(high/low)(dont let the device scale). also, make sure that your device isnt getting thermally throttled. if it is, it automatically reduces your cpu speed no matter what you set it to.

Don't worry about the score. It doesn't matter as long as your device is running nice and smooth, right?
hi guys i just want to know what is the max overclock of the cpu and the gpu for the nexus 7 ( please has to be has safe as possible, i dont want to damage the tablet too much, and yes i know that overcloking will reduce the life of the tablet) I want to get the best performance out of this tablet!!!!!
Note: battery drain is not a problem!!! I will use the nexus 7 for gaming most of the time and also browsing!!!
Please I really want to know i created an account on this site for this!!!
Most people can go to 1600 on the CPU. Any real world performance increase from the stock 1300 is negligible.
I wouldn't overclock the GPU past 446 (+30) because anything higher creates a lot of heat and people have reported benchmarks actually being lower once you go much higher than that.

Hi, tbh you'll probably not notice much if you overclock the cpu to 1.6ghz as percentage wise it isn't a large jump. Things may feel a little zippy at times though, in my house I have acces to two n7's, one stock and one overclockable to 1.6ghz. Ran tests between them and the 1.6ghz was fractionally faster, the difference was very small. Overclocking the gpu to 600mhz vs 416mhz at stock made a huge difference, as it it made some games actually playable. Despite the crap Nivida spit out about the tega 3 soc, it's GPU is comparatively weak. Over-clocking the GPU will give immediate performance increase in a lot of games. After doing heat and clock speed tests myself, I've found anything in-between 416-600mhz to give near enough liner performance increase and heat to be long term sustainable depending on the voltages your device can handle. Overall, I doubt CPU overclocking will give you much benifit, but if you play games the gpu overclock will. If your worried about heat from overclocking the gpu a lot, you can always use this kernel http://forum.xda-developers.com/showthread.php?t=1937146, which gives you full GPU clock and voltage control so you can undervolt your gpu to reduce heat. I wouldn't run at 600mhz unless I could undervolt the gpu as much as I have and I use that kernel because of it. I have my gpu overclocked to 600mhz running at 1225mV, which is only +25mV above stock voltage for 416mhz. Although most heat is generated from the transition period of the transistor charging/ discharging, undervoting does give a large positive effect on heat output if it's large enough. But 600mhz is a high GPU clock and the highest I'd recommend, tbh I would say 520mhz is a really good compromise between heat, performance and battery, especially if you under-volt the GPU at that frequency for most people if your not as annal with FPS as I am :silly:

AW: Nexus 7 Overcloking
You all probably have seen those 2GHz oc screenshots.Are those real?I'm not wanting to try this I'm just curious.
Sent from my Nexus 7 using xda premium
They are probably real
yes i have almost sure they are real, but puting the nexus 7 in 2Ghz will, i think will damage a lot the tablet!!!
The 2 GHz kernel was a test to see how far the Nexus 7 could be pushed. This kernel wasn't released for obvious reasons so yes, those pics/ benchmarks were true.
I know that the Note 3 got the Snapdragon 800 8974AA(GPU clocked at 450 MHz).
So i ran the latest GFXBench 3.0(Manhattan offscreen) and got a score of 11.1, which is even better than the scores the Snapdragon 800 8974AB(GPU clocked at 550/578MHz) got.
How can this be?

maybe its caused by throttling down due temperature
Maybe memory of Note 3 is faster and larger than other phone, which shouldn't be Samsung because S5 uses AC version. I think Note3 has very fast RAM and if other phone has slower (read cheaper) RAM it could bottleneck there. Also, as the other poster said the other phone could be thermally throttling, especially if the benchmarks were run multiple times to get average. You figure people running benchmarks would know better, but who knows.

The thing is that, other Note 3 get's around 9-10 FPS, which is normal for a 8974AA SoC. So either some Note 3's got the AB(which is unlikley) or Samsung is cheating again and overclocking the GPU to AB levels only for the Bench.

Samsung never overclocked anything, what they did in the past is ramp up frequency to maximum before benchmark started running, so there was no delay to get CPU/GPU to full speed, like you have with on demand governor. I don't believe it's cheating because you can set the governor to run full click yourself (if rooted) and benefit from this as well with any game/ benchmark. It also shows how inefficient ondemand governor is and maybe we should be using different governor setting which is interesting topic all by itself. I remember there was similar "scandal" few years ago in graphic card business, where drivers were optimized for particular benchmarks. Well, now all video drivers are optimized for specific, mostly graphic intensive games and we all benefit from it by having better performance, from lesser hardware. Maybe this could also benefit all of us by giving us better governors, so the phones can run faster with the same hardware, instead of being artificially slowed down with poor choice of governor settings. As far as other Notes running slower, thermal throttling due to multiple benchmark runs to get average would be my wild guess. Or maybe you deleted factory bloatware and change settings to make your phone faster, but no, you don't have AB version.
I've been using XBMC on the FireTV fairly successfully but wished it was a bit snappier. Thinking back to my days with the Galaxy S3, I remembered a great app called Seeder.
From the Play Store listing:
Seeder is a service for root users. It assists the kernel in "topping off" the entropy pool by re-seeding it with data from the non-blocking (high performance) random device. Optionally, it can also help alleviate MMC I/O contention by extending the I/O queue, allowing the I/O scheduler to make better decisions, and combine more writes.
After installing and enabling the moderate option on my FireTV, XBMC loads faster and navigates through menus much smoother. An essential app and well worth the purchase in my opinion.
Setup:
Root your FireTV (http://forum.xda-developers.com/showthread.php?t=2783805)
Install Google Play Store (http://www.aftvnews.com/how-to-install-the-google-play-store-on-the-amazon-fire-tv/)
Download Seeder (https://play.google.com/store/apps/details?id=com.lcis.seeder&hl=en)
Give Seeder root permissions
Select Start on Boot
Choose Moderate
Profit!
Seeder ($2.50) - https://play.google.com/store/apps/details?id=com.lcis.seeder&hl=en
Thanks for your tip. Does Anyone else recommends it? I am quite satisfied with the firetv performance but i am all forward with improvements

It does boost performance,even with my "overclocked" settings already made.
I quote it because I can't actually overclock the Fire TV because the lack of unlocked bootloader.
I can only change governor types to "Performance" on GPU,and "interactive" on all four CPU cores to boost them a bit.
I also have two booster apps for visual and touch performance increases,which prove to work really well.
I want to OC the GPU to a minimum 400Mhz and maximum 500Mhz to match the stronger equivalent GPU's 450Mhz and 550Mhz OC settings.
Maybe also get the CPUs on at least 1.9 Ghz or 2.0Ghz as the maximum with 500Mhz as the forced minimum.
When bootloader unlocking is possible,I want to find a fix for the kernel panic rebooting issue with Reicast caused by instability with certain Android ROMs.

Nothing...NOTHING about what you're doing is even remotely considered overclocking....
OC is pushing hardware past it's max performance out of the box or standard state. CPU's downclock themselves for power savings. You telling it to run at a different minimum isn't OC'ing, you're just telling it to not downclock itself so far.

Lighten up. In case you missed it he said he can't overclock and even pointed out his use of quotes.
If you want to be nit picky overclocking is not pushing hardware past it's max performance but TO it. Overclocking takes the hardware past factory spec, which you could call "standard state" but that is never near the max. It is set for stability and longevity not necessarily the fastest performance.
Intel used to push a new chip until it crashed then dropped it a notch and called it XGHz. It's why overclocking was so limited without changing voltage and needing extra and even extreme cooling. AMD always designed a chip to have plenty of room to grow and why they support overclocking and enabling extra cores.
AMD now has some extremely powerful multicore CPU processors up to 5.0Ghz!
It's called AMD FX-9590.
Beat that,intel!
Confirmed. . Seeder 2.0 actually does speed up the just about everything from watching streaming movies to using XBMC, except your Internet. . Highly recommended. Use the setting above and trickster mod.

intel destroys amd! and thats a fact! a 4.4 ghz i7 would still beat that 5 ghz amd in benchmarks! so its already been done

Not to go further off topic but benchmarks mean literally squat VS real world use.
I've switched from those S7 and Note 5 ports which lagged and had big delays opening apps to JDC OptimizedCM13 ROM which has basically no lag whatsoever. I read around that the kernel is what controls the CPU but the one I'm using (default one with the ROM, alucard kernel) doesn't support over clocking. What I'm trying to do is disabled core 3 and 4 to make a dual core processor but over clock the first two. With PC gaming people have always recommended fewer faster cores rather than more slower cores. Same with the Apple iPhones, it makes sense that fewer very fast cores would make the UI much smoother and from benchmarks it looks like Android doesn't use that many cores too often. I'm not doing any gaming, just light tasks only so I'm trying to save a little bit of battery but also make my phone smoother.
My specs are i9505 with Optimized CM13 ROM, default Alucard kernel. Using the TWRP 3 recovery (the ROM thread recommended it).
TL;DR a kernel for i9505 MM that allows over clocking and disabling cores.
There are none such kernels available for marshmallow.
And you reasoning isn't quite right.
It may be true that sometimes fewer, more powerful cores, might be better, but this is mainly due to the fact that the app, or program, wasn't made with multi-core devices in mind, and as such, doesn't benefit from a multi-core structure.
Another thing is that a few hundred MHz won't make a huge difference. Especially since you won't be able to go high enough due to the processor becoming unstable.
The highest I could ever go was 2.1 GHz, but even this wasn't stable. After about 1 day it would freeze.
Remember, phones and ROMs are required to meet certain battery life requirements. As such, they usually come with a balanced configuration.
