I remember back when I had a Galaxy Nexus that it was possible to not only overclock it's CPU and GPU but also its memory. Now this got me thinking that since the Nexus 10 has a less than ideal amount of memory due to it's high screen resolution, maybe overclocking its memory might help performance and multitasking.
Now the question is.... is this possible to do?
If I can remember correctly some of the custom kernels have memory controls. KTmanta comes to mind. I think you may need the kernels control app to get at those settings. Also I'm using Tempest ROM an OMNI ROM variant and it includes numerous memory settings which may be what you are looking for.
You would need to enable developer mode then Settings->Performance, settings select "tabbed mode" then select the "memory" tab.
I've never messed with those settings myself but they are there for your amusement.

Maybe try this

But of course depends on what kernel you are running, haven't used it on my n10 but works amazing on most my other devices

KT has memory frequency exposed and I think that is the only one. That being said, no matter what settings I try on KT, Trinity 10 outbenchmarks it with mostly stock settings. That suggests to me you should probably look for a different way to improve your RAM performance, i.e. minfree values.

Hi all,
I am using a rooted n7.
I have over clocked my galaxy s2 to 1.5ghz before, but I am not sure what is a safe level to over clock the n7 to.
What is a is is for battery life and performance?
And which kernel do u guys recommend
?
Thanks in advance
Cheers

I run trinity kernel on my Gnex and N7 and on my N7 I keep it stock speeds because I've seen no reason to realistically OC it. Most of the improvements I see are from the kernel software changes over stock. You can OC to 1.6 safely but I'm not sure of the power usage difference but I'm pretty sure the loss in power isn't worth the gain from OCing.

I have mine at 1.6 just for the hell of it, I get a good 4 or 5 hours of continuous usage out of it.

For the benefit of the community, can you tell us any major changes at 1.6 GHz?
Is there anything noticeably faster?
Hi, I have a related question but can't post since I'm new.
Using the glazed rom which i like but it apparently has gpu overclock. I would like to know how to adjust that back to stock setting or at least see what it currently is. I found the CPU section but there is no gpu I can see.
Is there a tool I can use?
Sorry for the hijack...at least its sort of on topic
IMO over clocking is a gimmick, its the kernel build

My thoughts exactly. I play some light games and web browse on my Nexus 7.
For those purposes, my Nexus 7 is already extremely fast, so I don't think I would be able to notice if it was over clocked.
But I guess it depends, maybe there's a big difference when running GPU heavy games.
I have OC mine upto 1640 MHz for bench marking alone for half and hour or probably more and it went fine although the tablet was getting warmer more than usual.

Hi,
I decided to flash trinity kernel.
I am currently OC to 1.5yghz, is that a safe level to keep it at full time? Or can that burn the cpu out?
Thanks again
Cheers
Corey
Edit,
I over clocked my galaxy s2 ages ago, and I noticed a huge difference in performance.
So that is why I want to over clock my n7 too lol

there is no such thing as a safe overclock. overclocking, by nature, carries some risk. that said, i havent seen anyone brick their device from overclocking.

Just wondering
Why do you feel the need to OC?
I go to 1.6 but use the Trinity App to go back to stock when OC not needed
Sent from my GT-I9300 using xda app-developers app
I have not over clocked the Nexus 7 yet but one way to test your devices max is to use setcpu. Make sure you do not have "set on boot" option selected. Then step up your cpu. If your cpu can not handle the over clock it will force restart. If you do not have the set at boot selected it will revert back to the last good state on restart.
Each device is different on what it can handle for over clock.

To be honest I doubt you'll notice much increase from oc the CPU since the CPU already is so powerful nothing pushes it to max really.
Only thing worth overclocking is GPU really. And at that, your not going to notice a difference unless your playing some intense games.
So actually I am a big fan of ps one games and I can't resist to not play ps1 games on my phone.
Well I am worrying about there battery drain here.
After playing a game on my epsxe and fpse(about 35 minutes) I go from 100% down to 69%
Is it normal? or not?
(also my phone heats up after this amount of time)
Most likely you need to change CPU settings, including voltage.

I am on stock android(rooted)
Can you recommend me a good Rom-Kernel combo ?
Cause this is my first android experince, and I am not sure what the best rom is for a beginner like me is .
I also do not want to damage my phone by tweeking with the cpu and voltage settings.
Should I wait maybe for stable roms? Cause I see alot of nightlies roms.
Also I am not familiar with the term "milestone rom"
Thanks in advance.
Any of the custom kernels should last a bit longer than stock. I use IntersectRaven's kernel. I have fpse but haven't gotten around to putting any iso's on here yet so I'm sorry I can't give any report. You could also try lowering the brightness while you play, and turning off data or just enabling airplane mode if you don't mind not being able top receive calls or texts while you play.

You can stick with stock ROM rooted but you can under clock it. The emulator doesn't need a lot of power, I use yo use it on my 600mhz phone so it should be fine with the nexus. Also stock rooted is the most stable.

Or keep the phone plugged charging while playing, this phone is a battery hog, i mean am not trying to generalize, but seems like some people try to multitask all day long on a mobile device with no removable battery, i mean really, think about a gadget trying to process console games, web, content, gps, screen activity, all at the same time, come on people at the end this is a phone not an alienwarelike or multitasking wireless gaming console

Okitche very
Thanks for the replies guys !
Should I use SetCpu in order to under clock it?
Also I heard many positive things about the franco kernel, is it worth giving a shot?

I haven't tried it personally but, you should still give it a shot. And setcpu is fine.

Most custom kernels lag more than the stock kernel.
If you want to go the custom kernel route for (at the moment) better battery life, go either CyanogenMod(the one included in their ROM) or Franco.
I've noticed that the default clock speed for the Nexus 4 CPU is 1GHz - 1.2 GHz (for my phone, anyway), but any attempts to underclock either of these values with many of the available CPU control apps have been useless, for after about a minute of usage, the clock speeds return to default, despite the CPU governor remaining as my choice.
I'm wondering if it's actually possible to effectively underclock/overclock on a stock ROM. If not, are there any battery-life optimized roms/kernels out there?
Sent from my Nexus 4 using xda app-developers app
Are you rooted? If you are, I don't think you should have trouble underclocking on stock. What app are you using to change your CPU frequencies? Try using a different one.
Trinity Four kernel has given me the best battery life so far.

You need to be rooted, use setCPU (app) or flash a custom rom
Can I flash the Trinity Four kernel over the stock ROM without having to wipe everything?

Hey guys, I'm new to the forums and fairly new to Hacking and overclocking android devices. However I have been building and overclocking high end PC's for sometime. So I am no stranger to the risks or processes of overclocking.
But I have some questions that maybe you all can help me out with before I start overclocking my Nexus 7.
Here are my Current Specs and Software:
Nexus 7 Wi-fi version
SmoothRom v5.0 + LeanKernel
Currently I am overclocked to 1500 Mhz Max with 204 Mhz Min + Stock voltage
I have been able to find information about CPU overclocking. But after extensive searching I have not been able to find much on Nexus 7 GPU overclocking.
1. Does my kernel support GPU overclocking?
2. If so how do I enable it? Or where is it located? and what settings should I be looking for (Names)?
3. If you need an App to overclock the GPU are there any that are free (Or at least one worth paying for?).... and which one if any supports my kernel?
4. Are there any good Nexus 7 CPU and GPU overclocking guides someone could point me to?
Basically I am looking for someone who is experienced in Nexus 7 overclocking, to point me in the right direction and help me with some indepth questions that may come up.
Thanks guys
What temperature is your CPU?

According to System tweaks App 39c to 40c while idling in that program. I don't know how accurate that app is though.... so if there is a standard better app to monitor your CPU/GPU temps I am all ears
I have yet to find an app that allows you to monitor your temps during load. Again if you can suggest one I am all for it.
Try trickstermod

Download trickster mod from the app store you should be able to change the gpu voltage there

Alright I will check that out. But what about GPU clock settings can trickster change those too??? And if so.... What setting am I looking for because I saw nothing referencing GPU clocks in those words
Sent from my Nexus 7 using xda app-developers app
It over clocks the GPU its on the 2nd to last page I think and you will see the clock speed and you can edit it, don't over kill though haha
Sent from my Nexus 7 using xda premium
Lean kernel doesn't have GPU over clocking settings. Try M-kernel, you'll find gpu settings in the specific menu of trickster mod.
I attached picture of synapse below with my current cpu settings and my question is is it good enough for performance and battery saving and can I do it even better?

only you know as we all use our devices differently. there is no such thing as best setting. since we all use our devices differently, best settings would depend on your usage. thats for performance and for battery.
I would recommend bumping up the screen off frequency one notch because with 500mhz, some music playing applications like tune in radio skip occasionally.
