I just installed Serendipity 2.0 w/ Glitterballs' latest kernel, which supports OC up t 1.2 GHz, and I wanted to know, is it possible to stably overclock my phone to 1.2 GHz without variable frequency or UV?
If so, how would I go about OCing my phone?
Also, will OCing affect the health of my CPU and lead to increased wear and tear in the long run?
Thanks in advance
If all you want is to overclock, you don't have to change anything.
Unless you plan on keeping your phone for 5 years OC won't do any harm.

Thanks MikeyMike01! Looks like I'm going to OC then. And btw, I'm a huge fan of your ROMs
As some of you might know, the HTC Desire S overclocks very well.
I've done alot of research, and I've found no difference between the MSM8255 chipset our Desire S runs on, and the higher clocked MSM8255T (which runs at 1.4-1.5GHz).
I've created this topic to gather some information on what method you use to over/underclock (built-in, custom, app etc), how high you've clocked your device, what governor you're using, and what temperature you're at.
Right now my Desire S runs at 1.4GHz, incredibly stable, ive stress tested for hours (so far) without any errors, maxing at bout 36,5c temp.
My current method is SetCPU, using 245-1401 interactive scaling.
Please post your findings / preferences / device settings.
I never overclocked my Desire S. Ok sometimes he can be slow, but I don't like overclocking a CPU of a smartphone... Maybe it's because I'm scared to blow him up or something, dunno. I just leave it like it was, in my eyes, the best thing you can do
I'm using OC/UV Beater2 which came in Endymion ROM. My DS is overclocked to 1,2 Ghz and it is very stable, never freezes
But I have a question, what is default undervolt settings? Because I think when I set for example -25 undervolt settings, that will come default setting after a while..
So I dont know what is default voltage... So if someone could tell what is though 122Mhz voltage, I would be happy!
1ghz ondemand. Sometimes 245/768mhz and in games 1.2ghz

Yeah, I've done some research too, and cannot find any differences about the 8255T vs 8255.
Ours are highly capable of going to 1.8Ghz stable.
What are the key differences?

245-1200MHz, interactive governor, using CM7 built in performance control. Phone is very stable, never had any problems because of OC. The highest temp i saw was +34C.

Same CPU 'issue' with the Arc and Arc S ->
http://forum.xda-developers.com/showthread.php?t=1396071
That pretty much sums it up, why the Desire S (some - mine?) overclocks so well..
Same thing they do with desktop CPUs.
Like my old C2D E6600 2.4GHz OCs to 3.4GHz without adding volts and running only on air cooling, 48c after 10-12hrs of stress testing with SLI nvidia cards in the case.
All in all, the MSM8255 and MSM8255T could easily be the exact same chipset/CPU, just at different speeds, some tested more extensively than others.
Has anyone tried running speeds above 1.5GHz+ successfully? 1.5GHz should also be doable, as the HTC Flyer has the MSM8255T and runs at 1.5GHz.

Ah!
Many thanks for that mate!
Been looking and couldn't find much info too!
Yeah, i guess the T stands for being tested more.
My Desire OC's very well. I can go to 1.8Ghz stable for very long.
(I don't usually OC though.)
I tried 2.0ghz too for about 10 minutes with no issues. but I quickly went back to 1ghz incase I had any issues.

My CPU clock is as in my siggy. I don't undervolt though.
I have overclocked my phone to 1.5GHz almost all time and I do not see any problem, it's very fast and snappy. I use Sense roms, CM7 and ICS without freezes or something like that. Battery life is nice for me, 1 or 2 days of use.
I've got mine oc at 1.2ghz and uv .75 on everything using ocuv and has been stable for weeks now with good battery life.
CM7.1 Stable
TIAMAT Kernel
SmartAssv2: 184mhz - 1017mhz
Screen Off: SmartAssv2 184mhz - 384mhz

Do you use setcpu? Can i use it also on latest stock cm7. 1 for desire s? Or is tiamat necessary? I'm mainly interested in undervolting -> better battery life.

Hi there,
Yes I use setcpu. Tiamat kernel is Undervolted by default which is good.
I'm my experience, I'm getting much better battery life with Tiamat kernel.
Are you on the nightly build or the stable version? I heard a few issues with tiamat on nightly builds, but not too sure!
Also a small note; undervolting doesn't help massively with battery life... the battery gain is minimal. On sense based ROMs, I UV by about 125V and it doesn't make a HUGE difference.
I think tiamat has really good battery llife as it has been exclusively optimised for our 8255 CPU by the brialliant Devs
Hope this has been some help to you!

I'm on latest nighly, which doesn't work with tiamat 1.1.5 (no sound). Nightly fixed some bugs which were crucial for me, so no way going back to stable.
Reason i'm asking: on lowveld's hyperions i got 8-9mA consumption while idle, on CM i'm always at 10-15. The min freq on both is 245mHz, which was suggested as lowest stable so the next difference i thought could be the undervolting... From battery stats i see that phone was not awake...

What bug fixes did the nightlies bring? Please share!
Hmmm... I guess you could just wait for CM 7.2, I think its coming very soon with the bug fixes, so I guess you could go back to stable from there, and use Tiamat.
My lowest CPU clockspeed is 184Mhz on CM (122Mhz on Endymion)
Its very stable for me. No freezes, etc
I use smartass2, so it will throttle up the speed in sleep if 184mhz is too low. When it has many tasks to load etc.
Not to sure how to Manually UV with CM, (as OC beater doesn't work - FC on me)
But on Endymion, OC beater app does the job.

Mainly bugs with voip calls. After htc released kernel sources, Nexx included them into the cm and the voip audio hack was not needed any more... Hopefully cm9 will be out sooner than 7.2

Yeah, hopefully!
Side note: on sense, i could OC easily to 1.5ghz, possbily more! And it was very stable.
But now with CM7, i OCed to 1.5ghz and it froze... I tried several times too ..
So does software depend on how much the CPU can clock?

I installed the ARHD 3.0.6 XE rom and my CPU was automatically overclocked from 1.2 Ghz to 1.5 GHz. This has brought some unexpected battery drain (it's much worse than it previously was).
Is there a way to underclock it to 1.2 GHz? I tried using the Daemon Controller app the rom came with but when I apply the changes, it simply reverts back to 1.2 Ghz.
Is there any safe utility I can use to downclock? Preferably free, but I wouldn't mind shelling out some bucks for a safe app.
Thanks to anyone who replies!
NoFrills CPU might be ideal.

Hi,
HERE YOU GO
This is daemon controller 2.21
uninstall the one you have and install this one.
It works.
Change your clock speed to 1.18 something and it will show 1.2ghz.
i flashed ARHD with overclock kernel
my cousin tell me it will 100% damage you device and its just from pcs have cooling system!!!!!! anyway:
how to turn it info normal with ARHD and all currently setting and... don't lsoe my data?
if impossible how to do it but i wonna my arhd rom and....
sorry for my English
plz fast...
I believe that the overclocked kernel that comes with ARHD makes the CPU run at 1.5 GHZ, which is the default clockspeed for the Snapdragon MSM8260 chipset, therefore it won't burn anything. Don't worry.

if you have normal sensation and your phone is over-clocked to 1.5 Ghz then don't worry as the actual processor speed is 1.5 GHz only and it was under-clocked to 1.2 GHz by default to support the poor battery(1520 mah one)
If you still want to go back to default
then flash ARHD again without superwipe( this wont touch your apps and data)
and this time just choose stock kernel instead of custom kernel
(in 4Ext Recovery it asks you to select "No" if you want to install stock kernel
afaik)
EDIT: don't forget to make a nandroid backup before trying this...(IT will save you in NEED)
AND most important of all
Dont forget to press THANKS button if you were successful
Some people even overclock theirs up to 1.7 GHz. Don't worry about it ... as long as your phone can handle it and doesn't get hot by itself, you'll be fine. Of course, it will get hot when using heavy apps or playing games, i just stop playing games when it gets really hot ... mine goes up to 67 degrees Celsius hehehe... just dont go beyond 1.7 GHz i guess. Thats the highest i will go, in my opinion...
oh if you want to underclock it, just use System Tuner app... dont go below 1188 GHz atleast(this is stock speed in Sensation 4G)
I'm at 1.7ghz with that Rom and no issues. It's nice.
I put my wife's at 1.2ghz still just in case there's stability issues as she doesn't understand those and just complains lol.

You don't have to do all that. You can flash a kernel by itself. You don't have to overlay the whole ROM. Reflashing the kernel by itself takes about 2 and a half seconds.
There are plenty of other kernels to choose from that will work with ICS, including the stock one.
However!!! You can limit the kernel you have to only allow it to clock up to 1.5 or 1.2 if it makes you happy. Just get System Tuner from the market. You can control the clock speed from it and limit it to whatever you want.
Also..wheveryone else said was true. You're good with the higher clock speed.
I use bricked kernel overclocked to 1.83. No worried about heating because the thermal protection built into the kernel will throttle the CPU speed down if temp gets to high. Just flask the kernel, and don't look back.
OK OK i trust you!!!!!!
OK i restore my kernel to 1.5ghz !!!!! and after a time i use the 1.5ghz i use 1.8ghz!!!!!!!!!! IF MY PHONE BURNS I KILL YOU:d!!!!
Here everything is expansive!!!!
is someone working on a jb overclock for tf 300t ?? ez overclock doesnt work anymore :crying:
maybe seanzscreams?? does someone have any info?? btw thanks for support
I'd like to know this too, any apps that work to overclock on JB?
The JB stock Kernel doesn't support Overclock.
You need to be unlocked and install a new kernel.
What if we're on a custom kernel capable of Overclocking?
There are already custom kernels for oc but u need to have a unlocked tf300 and a custom recovery
Looks like I found the answer to my question--it's through use of an app (such as system tuner or no frills CPU control)
Obviously, your tablet has to have a kernel that supports it, though.

Not so fast, there....overclocking with apps was a discussion I took part in a few weeks ago.
The performance controller built into Asus' roms control the speed of the processor, regardless of kernel. OC apps can only control the governors. Try using any app to set the speed to the maximum, and put the tablet in Power Saving mode, and see what happens
