I have the evo shift/speedy. Stock speed is 806. Overclockable to 1.9 to 2.0. Ran it for a day this week over 1.9 GHZ. .Doesn't really get warm with normal use.
HTC Desire S here. Stock max clock speed was 806 MHz. I am now using it at max clock speed 1516 MHz.
It's rather normal your device doesn't get noticeably hotter than before overclocking since the clock speed is an upper limit. Only during bursts of intense computational tasks does the CPU run at its max allowed frequency. The rest of the time it mostly idles at the minimum frequency.

Successfully OCed to 1.2 ghz (80 voltage) on motorola defy. My temperature is going up to 41°c from 37°c within 10 minutes of PSX gameplay...is it safe? and how high temp goes up so that it is on the safe side. I mean is there a limit to the temperature of the CPU after that it's dangerous?
Also should the freqeuncies of Max and Min be same? what's the difference
Please i need a fast reply on this !
thanks in advance
no reply? don't tell me no one knows this?
The min and max should not be the same. Min is the lowest you want the CPU to scale down too and max is the highest frequency you want to overclock too. On my HTC Desire min is set to 245 mhz and max 1113 mhz.
I don't know about the temperature, someone else should elaborate on that.

You should be fine... These CPU's are designed to run without a fan or cooling of any kind.

What is the best cpu frequency for stabile working, i use set cpu app for this.
I use 'coservative' scalling Min: 768 Mhz (when some problems i reduce to 748MHZ or 600Mhz when i dont need more performance) Max: 787 MHz or even 808 Mhz but this freq is too high. Is this scalling are good or use different (ondemand,performance)
Also i have question when my phone is blocked (screen is off) cpu freq back to normal low freq or still have the same freq like in set cpu app ?
No one can give specifics as even with one model of phone the quality of CPU changes so set frequencies differ.
EG: i'm using DHD with 1.6GHz OC "smartass" but some users top out on 1.3GHz, could OC more stable but don't need, regards underclock i've screen off "Powersave" lowest frequency 245MHz don't forget to set priority high.
There is more you can do with set CPU such as underclock on less battery so know get more for criticle phone usage, also temp based so again saving power.
Anyway best bet is to look for other users of x10 and see what they top etc.
Since installing builds 29, 30, 31 I have noticed my battery life shrinking and the xoom running warmer. Am I imagining things or are these builds overclocked upon flashing?
Nope, not by default. I'm running EOS 32 and it came set up like this:
Governor: Interactive
Minimum Frequency: 216 MHz
Maximum Frequency: 1000 MHz
Maybe you can use an app like System Tuner to undervolt your Xoom? Not sure what else could be draining your battery so fast while warming your device.
It could be my imagination and maybe I am just using the device more and giving it a workout when playing with all these EOS builds.
Thanks for the clarification.
Can someone just let me know what overclocked exactly means ?
is it helps to make mobile/tablet faster ?
CPUs have the ability to run faster than they are clocked by the manufacturer. The tablet ships with a CPU clock speed of 1 GHz. This speed is specified because the CPU manufacturer has deemed it the optimum speed (in terms of stability and possibly power consumption) for that particular CPU. By modifying the kernel, you can add the ability to change this maximum (and minimum) threshold. Theoretically, yes, if you increase the clock speed, your tablet will run faster.
The clock speed is how many cycles a CPU can do per second. So, at 1 GHz, a CPU executes ~1,000,000,000 cycles per second. By setting the maximum speed to 1.5 GHz, your CPU can now execute ~1,500,000,000 cycles per second. A CPU also has an instructions per cycle rating. So the more cycles you can execute in a second, the more instructions your CPU can process in that second.
You must keep in mind that when you increase the clock speed, you may sacrifice battery life and/or stability (higher frequency needs higher voltage). Additionally, even though we all have the same CPU in our tablets, there are small variances. I may have no stability issues running at 1.7 GHz while you may suffer boot loops running at 1.7 GHz. Furthermore, running at a higher clock speed may cause more heat and electronics don't operate very well when overheating.
Finally, the governors are used to regulate the clock speed. Just because your CPU is clocked to 1 GHz, doesn't mean it's running at that speed 100% of the time. If it's sitting idle, it may be running at ~0.250 GHz (250 MHz). Then, when you wake up the tablet and open an application, the governor realizes you need more CPU power so it increases the "maximum" until either 1) You no longer need additional power 2) You've reached the maximum threshold set by the kernel.
"The clock speed is how many executions a CPU can do per second. So, at 1 GHz, a CPU can process ~1,000,000,000 instructions per second. By setting the maximum speed to 1.5 GHz, your CPU can now execute ~1,500,000,000 instructions per second"
Not sure if I am misunderstanding your lesson. Please understand this no attempt to troll or argue, but Clock speed is a reference of the frequency of the processor. They are basically saying your processor has an operating frequency of 1 Ghz. Instructions per second is measured by IPS (instructions per second). For instance, My AMD Quad Core processor operates at 3.0 Ghz but can handle 42,820 MIPS. They are not directly proportionate.

You're right and wrong
IPS is a function of clock speed so they ARE directly proportionate.
(Clock speed) X (instructions per clock) = IPS
I used "instructions" to simplify the example but you're right, I should be using another word.
Thanks for pointing that out!
Thanks skinien
I'm having motorola xoom ... planning to root it to have ICS ... any idea what will be optimal overclock speed for it .... mostly for playing games on it

From what I've seen, a lot of people stay around 1.5. Just make sure you don't click "set on boot" immediately. Use it for a while too make sure its stable at your chosen frequency.

On ICS, mine is super stable at 1.4Ghz. My crashes, no reboots. And I'm using the Lagfree governor, so clearly I'm not locked in at 1.4 all the time. That's just the max speed based on CPU intensive activity...

Since Imnuts' latest kernel release and nitro's eclipse I've been none stop playing with my phone just like the day I got it. Anyways, I've overclocked the cpu to 1.3ghz. Very stable and no issues with stability. However I been using Quadrant to monitor changes I make and the impact it has on the phone. It seems to me when I overclock (any frequency) my FPS on my 2D drop way low and the 3D also drops. This significantly reduces the score of quadrant. I know quadrant doesn't mean anything but FPS difference means something. Also, upon investigating, I found if I change the govenor it also has an impact on the FPS. What is happening here and why?
thanks for any input!
I have actually noticed this also. Very curious.

This is how I found the best settings with the best performance. Set you governor to "on demand" and set frequency starting at 1100 then run quadrant, the first graphic is wall paper (yellow) appeared, look at the FPS, it should read above 20 (like 22, 23 or more), it's safe to increase your frequency to the next level. When you see the pfs in the wall paper scrolling drop below or fluctuate below 20 then the previous frequency is the highest you can use or max you can use. Once you done with this you can set the governor to anything you like, but I found that on demand is safe and save battery the best, since it's only use high frequency when needed. Min frequency I set to 200. try to run at least 3 times before move on to a new setting. Also I kill all running apps before running the test. In a normal situation you should be some where around 1200mhz and quadrant should be around 2100-2200. If you have a premium silicon chips, you can see higher frequency and quadrant score. Additonal setting for undervolting, try to decrease every frequency voltage by -25 then try -50 see which one is better for your phone. IMO, I think -25 is slight more stable. I also found that on demand is as good as kickass setting. Good luck.

Actually interactive, conservative, smartass, and powersave are better at battery saving, and smartass and interactive are also better at raising the freq when needed.
Sent from my pocket-sized, Linux-based computer using electromagnetic radiation... and Tapatalk.
My phone survive at 1400 freg with on demand but not with any other settings.
With Tegrak Overclock Ultimate with Interactive X governor, I am 1.252 GHz at 1.285 volts. Minimum scaling at 200 Mhz.
I am stable at 1.3 with 1.33 volts, so I decided to drop the voltage down to 1.285 and clocks down to 1.252 GHz. I didn't think that 48 Mhz was worth .45 volts.
My Quadrant score after 5 runs @ 1.252 GHz is 2649.
If you want "accurate" numbers in quadrant, you should only run with it set to a min/max speed that are the same. For some reason, Performance doesn't lock the CPU to the max clock speed, possibly due to adding in more steps. So if min=max for the clock speed, then run quadrant, you will get more consistent numbers. If you leave min and max separate, the governor may step up at different points (or down), causing inconsistent results.

No argument here, right on!
Thanks all for the responses. @Imnuts thanks for the insight. I set the min to 1400mhz (same as the max) and set the govener to performance. I received the highest FPS ever and received a score of 3112. By far the highest yet. 1400MHz is set to -75 mV. 1300, 1200 mhz are disabled and all others are -100mV and up. I'm not sure if it is really stable but it works without any restarts of FC. I guess this test kinda proves quadrant isn't a true test of the performance of your phone.
also, does our phone have a fps cap?
Hello!
as I finaly rooted my TF (after a year of stock ) I have already hit few obstacles while making it perfect. Now i have a question regarding overclocking.
My device: ARHD Rom with guevors kernel 21.4
I use my TF at 1,6ghz via SetCPU. In CPUStats it says it doesnt use 1,4ghz and 1.5ghz freqs at all as the time at those freqs is zero. But when I clock it up to 1.4 or 1.5, it does use them (note: when set to 1.5ghz, 1.4ghz freq is still not used). What could be the reason for that?
Thank you for your answers
miHah
Looking at cpu histories it usually defaults to the lower stuff except when you do complex calculations, in which it uses as much as it can until it's done. That's why it doesn't use those middle freqs as much, if that makes any sense.
I agree with Thing o Doom. A lot depends on what the processor/software decides it needs or wants.
I stopped using a wide range of frequency like 216-1200 and stuck with a straight 1200MHz only on the min and max.
Depending on the CPU load will determine whether it even hits a certain frequency and also based on the type of governor.
If you have a governor that is set for performance and your range is 1400 - 1600, the governor interacts with the rest of the system and may ramp straight up to 1600 without every hitting 1500.
Hope that expands on Doom's answer.
I use interactive gov. and usualy cpu clocks scale at every cpu freq described in kernels scaling. I use 216-1400 now and cpu uses all clocks in that range (depends on the need ofc). But if i use 216-1600 then not all of the freqs are used. I meant to say if u scale it to 216-1600 there should be some point where cpu would use 1400mhz freq, but mine doesnt at all. So the scaling goes from 1200 directly to 1600 and no in between resulting the cpu to be more time at higher clocks when not actualy needed (when it could just use 1400 or 1500mhz).
Anyway, i now use scale of 216-1400mhz and seems to be working great dunno why I even bothered with 1600, but this one thing not scaling at those two freqs did scare me as I thought there is smth wrong with my tf
