i searched the forum bt wasnt able to get an answer which i would understand so cn any body explain me wht is overclocking?
The clock speed of the CPU on the Tilt2 is 528 Mhz. This is the fastest safe speed the CPU is certified for by the manufacturer. Overclocking allows you to make that CPU run faster. Many do this with no ill effects. I've always had random lockups so I do not overclock.
overclocking is...
making a processor run at speeds greater than the manufacturer intended.
so. in the case of the rhodium (touch pro2/tilt2)
overclocking is increasing the 528MHz processor to a higher clock speed.
overclocking the rhodium's processor should...
in turn. increase the performance of the overall device.

I'm having some trouble with GPU performance with my Epic 4g on stock EC05 with the Genocide 2.0 kernel.
From my research I conclude that I should be getting ~45-50 fps in nenamark1 v1.6 at stock clocks.
My device can only push out 38fps at 1000mhz and 40fps at 1300mhz - something is wrong here.
I have tried the Syndicate frozen 1.2 rom with the Genocide kernel and achieved the same results. I have since gone back to stock rom.
Does any one have any ideas as to why I am getting such low scores.
yeah i tried on srf 1.2 and actually got 30.3.
ok srf 1.2 oc'ed to 1.4. are you sure your actually overclocking? download a program called cpuspy and see if your actually hitting 1.3
edit: btw i odnt think its possible to get any where near those kind of fps without overclocking..

yes, 41.5 fps max at 1.3ghz Something is wrong. shadow Guardian is fairly choppy as well.
My gpu is gimped...
Which Governor? If using "conservative" I don't think it tops 1000 or 1120 even if overclocked to 1400 unlsee you use the very first Voltage Control. Rodderik doesn't support the new Voltage Control or SetCPU. I brought this up to him a while back. He said to use the Voltage Control in the OP of his thread. Just trowing thoughts out there...

I only know how to change the governor with setcpu, I don't see a way to do it with voltage control.
My CPU is fine I think. SetCPU also works fine to change the governor. Running the short bench, the lowest result on stock was about 181 ms. Overclocked to 1.3ghz I got 136 ms.
I'm also getting great speed in CPU intensive applications like the n64 emulator n64oid. GPU limited apps like Shadow Guardian and Quake 3 aren't doing as well.
I wonder if my gpu is somehow on power save mode (if that's possible)
Can someone compare their setCPU short bench results to my score of 136 ms?

More or less what I'm getting. I doubt your gpu is gimped man. And your cpu is deeply integrated with your gpu. Don't think of it like a desktop setup think more like a laptop. Where the gpu is supplemented by the cpus power. 41-44 fps would be normal for 1.3 ghz. What I get at least.

I know a hell of a lot more about notebooks than I do about android phones, and even integrated graphics chips are independent from the CPU. Sure they may be manufactured on the same silicon with the cpu but they can be clocked independently (and even turned off).
The problem with the epic - and android by extension - is that you don't have direct access to the GPU or its driver. I've read that some kernels for certain phones can allow you to overclock the GPU; though none exist for the epic. An yes, I know about chainfire3d, and it's not really a 'driver'.
At least battery life is good for me...

As far as I know, this might be exploitable in GB, which is why you are running into problems.

What you said about graphics chips might be true.. But it still doesn't change what I said. The problem is not with your gpu. Its with your settings. You may prove me wrong, but what I said is that your gpu directly relies on your cpu. That's why you get a better framerate when you overclock more. Chainfire has nothing to do with this.. I'm sure you know this but its purpose is to fool games by converting "commands" for a certain gpu into another and downsampling textures, etc so that they can run more efficiently on our chips. Ask anybody else what they're getting on that bench and they'll tell you similar numbers at the clocks we discussed. Btw I'm not sure but I think the gpu drivers for our phones might be closed source. Which would explain why oc'ing our gpu would be impossible without custom ass drivers built from the ground up.

Waaazuuuuppppppp Guys?????
Can anybody tell me if it's dangerous to overclock the CPU to it's stock clock speed (the stock 1,5 Ghz of the OMAP 4460, not the stock 1,2 Ghz of the GNex).
I was thinking that it will not harm the CPU in any way because the OMAP was designed to run at that clock speed, am I right?
Hope anybody here can help me with my question

Depends on heat really. I'm sure it can run 1.5Ghz, but the increased voltage needed and the associated heat will shorten the life of the processor. I've had issues while charging and using nav on the phone where it reboots due to heat on stock clocks...I'd really not advise going to 1.5Ghz without proper ways to cool.
Every phone is different, some handle overclocking better than others, I haven't had any of the problems described when overclocked to 1.65GHz, but I'm sure others do.
I'm running KT747 (Build 3/14/13) and I'm just wondering what this stuff is and does it affect my battery/performance, and if so how? Thanks to anyone that can help!
Overclocking speeds up main processor past 1.5ghz, kernal must support this function. Underclocking slows processor speed to whatever you set maximum under 1.5ghz. Under is good for saving battery, but can cause lag depending on how you use your phone. Governors control how the processor handles requests, such as opening an app, with on demand gov, processor ramps up quickly, with lagfree gov, processor kinda takes it time, which in return saves battery. If your not comfortable or understand this totally, be careful, search for guides on xda about overclocking and governors. Overclocking can cause bootloops, freezes, or other issues. I overclocked mine to 1.7ghz with no problem, but I'm running Agat kernal.

Curious if overclocking the CPU and GPU is really worth it looking at performance vs battery life. My device seems zippy already, but I'm just wondering if overclocking would improve anything seeing as some other tablets are moving onto 2.0+GHz.
If so, what kernel would you recommend me to use?
I would not overclock it, if you think it is very fast already. Overclocking from 1.5GHz to 2+GHz is probably mostly used for people trying to get the highest benchmark score.
i used to test roms and over clock the kernels while testing now iam back to basics
as i noticed even with a small overclock the system got hot around camera area on most kernels
that was enough for me to stop oclocking
