Not really. As faux say not all chips are created equal. I've seen up to an amazing -150 but my phone can only handle -50 stable and -75 sometimes with a reboot or two.

Mine handles -100 just fine, but yeah,others can only go -50. Just use system tuner and hit the -12.5 till your phone freezes, then when it restarts go one less and see if it's stable. That's what I did.

I'd also suggest keeping the Max Clock at a consistent value while you play. E.g. UV -100mV might work well at one Mhz then fail at a higher value.
Mine seemed to work consistently at about -100mV, then again I tend to UC unless I'm running CF-Bench or something

Should I only need to concentrate on the lowest and highest clock speeds it's been set to use? Or will I have to undervolt all other frequencies between the two? Not sure if it increments on usage, or simply toggles between the min and max.
If it does increment, how can I test it's stability on the other frequencies if I can't tell what frequency it was using at the time?

Just tapped the -12.5 button a few times, and it reduced all of the sliders. It's -100 now with no apparent issues as of yet.

May I ask the reason for undervolting?

Mainly to save battery. Altho I have found that it is quite negligible. It may also help with phone heat

I run faux latest version 2.7 beta and I see his scripts to undervolt and the lowest I see it too go is -75 how are you able to go lower to -100.... ???

I think it varies from phone to phone, mine too seems happy enough -100.

If the phone hangs/boots below that level then with the Phone/Kernel/... that's the limit.
I created a GScript script (well a sh script) to U/V after a reboot. I didn't want it to do it automatically as you'd end up in a boot loop. Just hassle to fix. The reason for the GScript was to remove it from the various CPU controllers I'd tried, I ended up just using the CM7 one to control the CPU.
Faux has the command to do it globally (across all frequencies) or individual frequencies. TBH I never bothered with individual ones.
The bottom line is, do what you and your phone are happy with.
EDIT: meant to add you can check the actual value manually. I know the Faux one (same post as the scripts above) but if you are using a different kernel it might be in a different place.

Best settings for SetCpu in Htc Desire S

Can anyone tell best settings you guys are using in Set Cpu
Thankxx

Best in terms of speed, battery life?

best thing is not to overclock as this can reduce battery life, so i use 2 profiles in addition to the normal one which is 245-1024 scaling=interactive, the other two profiles are
245-768 at screen off scaling=conservative
245-368 at battery<16% scaling= conservative(u can try powersave but its too slow then)
hope this helps

i have little problem. even if i set intercative 245mhz-1ghz after one day or simply later it freeze at 245 mhz. phone is then very laggy and i have to change profile to get it to work again.

yes probably a bug, never had this problem try changing the scaling or do a clean install again, but interactive is more cpu aggressive so it provides better performance

What about overlock
What is the scale to have it
What about
Sampling
Power bios
Thankssss
Sent from my HTC Desire S

overclocking depends on the kernel you have installed, most of them have a max of 1.5 ghz("Safe" limit), but generally its not good to overclock for the battery and for the phone itself unless for a short time and you can use whatever scaling you feel appropriate.
as for the other questions , i have no idea about those

well i would recommend to adjust to 368 min, since most of the time the phone is on standby and 768 mhz are not needed on standby it will only consume your battery, but you can keep it the way it is if you feel that way

[Q] Sensation overheat..

My battery overheats and gets up to 56C!!
Probably because i wiped the battery stats because after i did that it always warms up so much. My battery also drains very fast (after 30 minutes of playing 40% are gone).. Is there a way to fix this problem?

What ROM, firmware, kernel? Are you overclocked?

IMO your battery usage when playing games sounds normal enough to me.
I second what the above poster has said. Are you over locked? Also, I doubt wiping battery stats would make your phone run physically warmer than usual...

Haha 1.51ghz ?? The CPU runs at 1.5ghz by default lol (if u have XE ROM) there isnt no point overclocking by 0.01 ghz
Anyway, Update your ROM ARGD is on 6.6.2 now.. that might improve things.
Also, When playing games the phone does get hot, Mine does it too its normal. Even more so if you have a case covering up the back too !
dont panic you'll be fine, and if by any chance your phone catches fire and burns you.... You can sue HTC and get the newest release for life

Lol thanks for helping.. I can't wait for my phone to catch on fire now
and for some reason my cpu is 1.2 ghz by default. I know phones usually get hot while playing games but 56C is too much isn't it?

well under hardware information it will say 1.2ghz but the actual processor is a 1.5ghz, But it has been downclocked to 1.2 by HTC so they could release the XE version as a 'better, improved version' (which is bull****, Its the same phone)
I only mentioned the fire part cause it was in the news last week lol

i ran cpu benchmark it showed 1188 mhz..

Undervolting my sensation

I'm a noobey and I really don't understand how to undervolt my phone could some explain how to undervolt a sensation for better battery,etc.I would greatly appreciate it.
Sent from my HTC Sensation 4G

Under voting works by reducing the amount of power drawn to the phone at a selected frequency. You can do this with an app like system tuner or setcpu. However I can't give you a set of voltages for it, because usually there's minor differences in the hardware of people's phones, which means some values may work for some and not others. I would advise to try reducing the values slowly, and do some research on other people's values to see what they have been able to reduce to.

Is this undervolting I use CPU set and I keep it at min 192mhz to 918 MHz.I thought this was called underclocking.Am I wring or correct.How do you actually set stuff to mv?I don't see and settings on there for mv.and what are all the different things that I can actually down set the mv on.could someone please explain alittle more.
Sent from my HTC Sensation 4G

What you did is underclocking, which saves battery but also reduces performance. Undervolting needs a kernel that supports it. You can set the mV for every mHz. I usually put it 50-62,5 mV lower than the standard voltage.

@ mesaman2012
Download System tuner (or Buy its Pro Version)
Start System Tuner.
Tap on "Voltage" button (in 2nd last row)
there u can increase or decrease the voltage (by -12.5mv to +12.5mv)
after u got ur desired voltage Tap on save to save it.
Simple....isnt it ?

I set all the setting to the lowest +12.5 volts.I hope that's alright.any input on this would be greatly appreciated. Thanks!!!

Now download stability test from Market and run Scalling test,leave it for 15-20min,if its stable undervolt one more step the again stabity test for 15-20min.When test crashes rise voltage for one step and thats it

I dont rely much on undervolting for saving battery i mean it just depends on your usage mate or either way get an anker battery

Does the way I have my phone underclocked matter with undervolting at all?I keep my phone at 192mhz to 918 MHz for just normal use.I undervolted everything down as far as it would go then I +12.5 and when I was using it right away my phone shut off.so I then did another +12.5 and now so far its running alright.I'm going to do a scalling stability test next.If I'm doing anything incorrect let me know please I'm just a noobey. Thanks!!!
Sent from my HTC Sensation 4G

The only way the underclocking influences the undervolting is that you have less mHz values to set the mV for, so for example if you underclocked to +/- 1200 you can't set the voltage for 1500.

Who has undervolted there sensation and seen a noticeable gain in battery?would you say you got and extra he or 2 on a full charge?

I'll try to report back in a week or so. I went from running the standard 384-1.51 to 384-1.72, to now running 192-810, testing undervolting as well. Will have to play more for sure.
Previously, I had the screen off, not in call max frequency set to 810, while screen on was stock xe. I noticed quite a bit of time at 810, so something is consuming excessive cpu clocks when the screen is off.
The major bummer I'm coming across is that system tuner cannot undervolt below 800mv. Since the phone is ideally spending most of its time at the lowest fid/vid state (192 or 384 for example), there's a good chance of stability below 800mv. I haven't done too much research yet to see if this is possible with some other means, but this may help a bit in standby. Of course, if I could just keep the damn screen off, I'd probably be in better shape.
How much less battery do AMOLED screens consume? Saw a One S today, and it does look pretty damn sleek.

Thanks. I've been running Faux's kernels ever since I got my Sensation. I wonder if he'd consider adding the feature. How low are you able to go stably below 800mv and at what frequencies? Figure if I'm going to be idling at 192 or 384mhz, I'd like to get that voltage as low as possible.

Thanks for all the great input.should I change to a bricked kernel?If so what version.I'm running v008b4 faux kernel right now should I use a lower version like a v005?

[Q] Sensation Heating Issue!!! Probable Solution!!

Pardon me if i have brought up silly or crazy question but I have to ask it
I have a sensation and have been using vipers rom from very beginning with cpu to 1.5Ghz and 3d/2d slightly overclocked. and there is heating issue at area around Sim/sdcard slot and front screen part while surfing web or playing games(basically while using resource hogging apps) That's where cpu is located i believe. [also the phone starts lagging when it heats TOO MUCH]
Then past month i clocked every thing back to sensation's default. it helped to cool the temp lil'bit.
Then few days ago I switched to Sultan kernel which dramatically makes my phone lot cooler than it used to.(but still heats up) I overclocked to 1.5Ghz and is still cool. Undervolted to -50 worked fine. Then i started to tweak 3d/2d gpu overclock/underclock and it heats up like before. So, here i think proper tweaking the cpu,gpu can generate less heat on the phone but I have tried many things as i mentioned above and i am not sure what exactly is making the phone hot or cool down or what to do about overclocking/underclocking/undervolting, etc,etc,etc
So here I am asking other user for their guide for proper tweaking the phone to its best performance without heating it up. Any suggestion??:silly: what cpu freq?? 2d gpu freq?? 3d freq?? undervolting?? leaving stock??
I dont mind clocking the cpu to 1.2ghz or 1.5 ghz.. the processor on sensation can handle upto 1.8 or so just fine. But all i want it to generate less heating, more performance and definitely more battery life.. so any suggestion?:fingers-crossed:
This info can help other noob out there (specially me) to tweak their phone without worrying what to do and what freq to use....Cheers
For more info i use anker battery.. and as far as i know battery is not the cause for heating on sensation.

Bricked is the best kernel for the heating problem. Don't oc the cpu and gpu and you should be fine. The only problem is that bricked is a bit laggy
Sent from my HTC Sensation Z710e using Tapatalk 2

overclock gpu produce much heating (my experience) and that also bring not much more performance. Overclock cpu produce of course some heat too, but not that much. Also undervolting the cpu reduce the heating.
I think the coldest one are, which are more close to stock.

Hi,
Overclocking whether CPU or GPU will definitely cause heat, you cannot have both performance and coolness besides each other ever; in case you want performance, then you have got to tolerate high temperatures and further, a bit lag. But if this heating thing bothers you too much, then you have to stay with a lower CPU/GPU frequency. In this case, if you still do not want to lose your performance TO AN EXTEND, then I recommend flashing an AOSP/KANG ROM instead of Sense based ones.
Good luck :good:

Unfortunately bricked didn't worked out for me, also was a bit laggy like u mentioned.
I have set the cpu to 1.2Ghz and both 2d/3d underclocked with -50UV.. As of now working like charm.:good: But I wanna know, Does underclocking Gpu has any effect on performance??

In case you've flashed Sultan Kernel in which Ville C2's GPU drivers are included, then IN MY OPINION there would be no problem at all.

don't worry for the heat my phone goes up to 80°C and is still working fine. no problem at all. so remember to not use 1800 mhz use max 1620mhz and max 320 gpu 3d. will wil get good perf. always use PYD-X or SB FM (ICS) or (JB)

Underclock your 2D GPU to 145MHz on my kernel. Underclocking the GPU can make transition animations and games laggier HOWEVER unclocking the 2D GPU instead of the 3D GPU will do no harm and the difference is barely noticeable. Your homescreen will also be just as smooth as before because Rosie is rendered by the 3D GPU, not the 2D GPU. If underclocking your 2D GPU to 145MHz doesn't make your phone as cool as you want it to be then you can also lower the speed of your 3D GPU. If your phone is still getting hot after unclocking your GPU then use a more energy efficient CPU governor like Badass or Intellidemand. Also, in my kernel's Aroma installer, enable mpdecision. The mpdecision in my newest beta for Sense ICS ROMs (r18b3) works best, so install r18b3 and see how you like it. You can download r18b3 from here: http://goo.im/devs/sultanxda/Pyramid_Sense_BETA/Sultan-kernel-r18b3-Sense-Aroma.zip
