I'm using Siyah Kernel and all I can see in the ExTweaks is one option in GPU which is GPU lock which has a minimum of 500mhz and to a maximum of 1200mhz.
How can I underclock or change the GPU frequency settings like this:
GPU: 100MHz-160MHz-266MHz-400MHz
TIA!
Earlier beta versions were possible with extweaks.
I am sure future releases will too.
I am sure GM had is reasons, maybe stability.

If its not possible with extweaks what other options can i do to underclock the gpu?
1. Wait for future releases, can't be that urgent, can it?
2. Flash an old beta release. They are beta for a reason......
I would go with option #1

I've been using SetCPU for profiles, OC, and UV my phone. However I notice that the Tegrak OC app gives the user more control with tuning the GPU and I/O scheduler in addition to everything that SetCPU offers. Can someone who's been using Tegrak for awhile provide their voltage settings (since its more detailed than the voltages in SetCPU) and if possible any GPU settings/voltages. Also does using a certain I/O scheduler results in a noticeable improvement in performance or day to day usage?

hi,
please can u help me, when i tried to intall tegrak on my i777 from the market it says " device not yet available" , did any one have the same issue ??
thanks
When i use set cpu and set the highest clock at 1 ghz it still goes past it to 1.2 ghz. Im useing siyah. Any help will be appreciated.

I doubt your kernel has anything to do with it because Siyah's kernel does support both OC and UC. Do you have any profiles that have a maximum of 1200Mhz instead of 1000Mhz? Those could be kicking in even when you don't want them to if you aren't careful.
Sent from my SGH-I777 using XDA
Nope I'm not using any profiles. Although in CWM in kernel specific options I did select performance mode if that has any thing to do with it
Sent from my SGH-I777 using xda premium
Try deselecting that option or selecting a different one. I don't have a ton of experience with Siyah, but a performance mode sounds to me like it will default to the maximum CPU speed. Which on the SGH-I777 is 1200Mhz, stock.

Performance is a Governor for the CPU that sets it to Max frequency . That's what its FOR. So its doing what its supposed to. As previously stated you have to switch to a different governor in order to underclock.

I'm not talking about the governor in CWM there is a option for default, battery and performance
Sent from my SGH-I777 using xda premium
No, he doesn't mean anything to do with CWM. When you're selecting or switching to a governor, a list comes up and depending on the governor, your CPU will behave a certain way. If the maximum is set at 1200Mhz and is going to that speed when you have performance governor on, that's what is supposed to happen.

Uninstall any other clocking apps and clear application data (manage applications) for SetCPU.

Change your governer to something other than lulzactive.
lulzactive forces your CPU at a certain rate. Thus, the "active". and the "lulz" on my end.
Since we now have Perseus kernel and we can tweak stuff, the cpu is easy enough to tweak. But for the gpu and voltage and charging etc... what's a good app that is compatible? I used to use STweaks with Siyah. But don't what's the best all round tweaking app

They are just benchmarking programs are they not? The OP was asking about a program that allows you to tweak the rom like Xtweaks or any of the others.

Yeh I never run it at the max just for saftey precautions, I already know how to tweak the CPU i am actually talking about tweaking everything else do you know any other software like Stweaks for Siyah?

For GPU clocks and voltages you need to use scripts.

try SetCPU you can alter the governor and the voltage plus you can also check if the undervolt you did is stable

Gpu overclocks itself on-demand, I didn't implement anything for user control, instead it is better to be this way

On this device even 1.5 is borderline. Anything over THAT u got problems.
1.48 is the most stable safest and still really damm fast.
Be mindful of governor settings. Research your kernel before taking on OC mods.

You most likely have a performance option that came with the Custom Rom or are running an app that has System App access , which will over ride a User App. Double check all apps and settings to see if you have any other programs that have system user rights to your CPU, that is most likely what is over taking your desired settings.

Thanks for the quick reply, I'm on the Android Revolution HD 8.0 ROM now, that is probably the reason for this. Can I do something with this?
Sent from my HTC One X+ using xda app-developers app
Open up the app your using to undervolt, these should be an option to restore default values. Once back on default go ahead and open the programs' App info and disable or freeze it. Reboot and run your CPU spy app and see what is taking charge of your voltage. Also possible your voltages are not sticking which has to do with the ROM. Id suggest running profiles for CPU rather then undervolt. I. E. 534 mhz - 1434 mhz when screen on, 348-1012 when screen off. SetCPU is what i use. You have less of a chance of frying the motherboard and doing irreversible damage to your phone internally

Undervolt has to do with lowering the power that goes to the battery. when desired mhz occurs, where as underclocking has to do with specifically CPU processors and with a specified setting (screen off, music app on) occurring. Just to clear up my previous post. Undervolting the battery use to do wonders on phones a few years back because of all around poor battery life on most devices. But nowadays it is pretty pointless.

The only app that seems to work properly with Sense stock kernel is Tegra Overclock.
