I was using stock for my gtab and lately installed Overcome-Hermes.
I noticed that the 1.4ghz oc using setcpu is unstable and often hangs in games especially "Dungeon Defenders" using the default assigned voltage of 1500mv
I played with the voltages for a while and found out that the 1.4ghz OC is stable when i set it at -75mv which is about 1425mv.
Is this normal? Aint the higher clock supposed to require more voltage?
Device does not freeze up, not even once so far, when i undervolt 1.4ghz to 1425mv.

i think its normal since it states here: http://overcome.mimzo.com/?page_id=68
"THOUGH FOR HERMES, BEST STABLE SETTINGS SO FAR: -100mV AND BELOW."

My experience with gingerbread UV/OC states that the higher the OC the lower the UV. However, seems that some UV is necessary for OC; especially for 1.4Ghz.
My setting for that frequency is the same; -75Mv and seems stable for a couple of days.
And yes and no, although higher frequencies need more power higher voltage is not a must.
Last note and 2 cents; if it is stable do not bother )
Something is not right here, with Froyo I had -200mV at all speeds - stable withouth problems, but with GB and -100mV the tab already unstable at higher speeds...

What is your stable OC frequency?
I'm curious, because we can see kernels supporting up to 1600Mhz and in other hand I can see my device not working on 1200Mhz
i have been running @ 1.4ghz stable but no luck with 1500 and 1600...
I've been running at 1.6GHz on the Captivate for the past 2 weeks.
voltages are 50/50/0/50/0/0/0/50/50/0/0/0/0/0.
StabilityTest completed 36 passes, reaching a max temp of 42C and receiving 0 errors. Using Setiron's SuperOptomized 1.5.4 XT Kernel / personal JK3 build.
Battery life is better than expected, but could use some improvement! But, running .6GHz faster than the specified frequency, I guess i have no room to talk.
i dont overclock, find it too unstable
This isn't dev...
XAN for me with laststufo stable at 1.3Ghz max OC with -175mV or -200mV
1200mhz only can work for me within 10 minutes before it freezes
1120mhz works perfect
1.2Ghz stable using Trasig's Advanced Voodoo 5.
where is raspdeep? will there be anymore oc kernel from him?
where can I find Setiron's kernel please?
international SGS I9000 16gb version

pretty stable and fast, best experiance with the deadline scheduler, jfs+ext2 binds on Lagfix
best setup till now with quadrant scores not below 2100 (usually 2300-2500)
1.5 is possible but not as stable as 1.4 and 1.6 is impossible
current Voltage settings are: -175 -175 -175 -175 -25 -25 -50 -50 -50 -50 -75 -75 -75 with 1.4 set on boot
noticed a stutter like lag every 1 sec interval with any voltage above -175 on 1.4Mhz

same here linpack works on 1.5 but unfortunately not stable for daily use (scored 22.something-Avg of 3 tests)
quadrant gets to I/O and freeze there @ 1.5
simply stick with 1.4 since the phone is happy with it, unless theres more work done for the other freqs regarding stability, im sure we'll get there since long back 1.4 was available but totally not stable and now its working flawlessly, just keep an eye out ^_^
BIG thanks goes to all the devs working on all the lagfixes/OCing/Stability/Kernals/Roms etc etc etc.....
But, how are guys undervolting? Thats the issue right?

XAN's voltage app , check it out in the dev section
I know...I meant which UV values according (stability, etc)
I can OV no probs, but undervolting is tricky
Nice OC results ppl!
I'll post mine...
1.6Ghz on the Captivate is for real ? I heard its not even performing any faster than a 1Ghz international SGS.
That's right.....I think all this overclocking is irrelevant.
Finding the right balance between overclocking and undervolting, keeping system stable with good battery performance, that's the thing
Comparing OC and benchmarks, is kinda childish really:

How far is your Galaxy s stable?
mine just hits the 1.1GHZ, beyond that only crashes no matter which voltage i Use. please Use the poll so we have a good picture of what the average galaxy s is capable of..
also comment which version of SGS you are using and 8gb/ 16 Gb etc..

PS this thread should be moved to General
had mine at 1.54ghz running MIUI with tk glitch kernel.
was amazingly fast, but my phone got hot quick, i dont like OC'ing i feel it may do more harm than good in the long run.
others may and will disagree but thats my opinion on it
Mine with 1.3GHz OC and some Undervolt is perfectly stable.....

Agree with the chef ...
Although I can overclock to 1540MHz it does get hot and Im sure it will do damage in time ..
1300MHz is a great overclock ...
It will be interesting to see what my SGS 2 can be safely overclocked to
1.2 GHz seems ok for me - with UV
Doesn't really get hot.
Running mine @ 1440 MHz with MIUI but i think I can go higher if I want . I have the 8 GB version
1.3 and very stable and with great performance both q score caffiene mark and in daily use
Which voltage are you using?
Mine seems to freeze on voltages above the 1.3V,
above the 1.2 GHZ always freezes. I,m using darkeys 9.5 Rom.
someone some advice which rom is the best for OC, (just for benchmarking) for once.

Mine can handle up to 1.3-1.4ghz
Im getting stable speeds of 1.7ghz. Im on watercooling though..
Sent from my GT-I9000 using XDA Premium App
1.4ghz is my max for full stability. 1.5ghz works fine (no reboots), but the CPU occasionally gives an invalid result during calculations, e.g. during benchmarks like linpack, results can sometimes be inaccurate; 1.44ghz also seemed to work, but I picked 1.4ghz max for longevity/reliability.
UV Values are:
100mhz - 200mV UV (750mV)
200mhz - 150mV UV (800mV)
400mhz - 100mV UV (950mV)
800mhz - 75mV UV (1125mV)
1ghz - 50mV UV (1200mV)
1.2ghz - 50mV UV (1300mV)
1.3ghz - 0mv UV (1400mV)
1.4ghz - 50mV UV (1400mV)
Max UV were found by starting from 100mhz Max frequency, decreasing UV until stable for 5 minutes of software decoding of 720p MKV, and then increasing Max frequency one step. Occasionally the previous step UV needed to be decreased by 25mV to obtain a stability at the next frequency step.

Mine is stable at 1.5 Ghz with a 200mv undervolt, but only if I select it as a single frequency.
For multiple frequencies, I was stable at 1.4Ghz on an earlier kernel, but it's slightly unstable now... I'll probably try tweaking the governor.
I'm on a i9000m using tk-glitch's V9D-VC and CM7 #11 build.
By the way, shouldn't this thread be in general?
I am on MIUI v3 and CM7_SGSMTD_platypus-kernel_20110522_r0_quorra-prer11_test4-r2 kernel.
I don't use undervolt settings and 1.2 Ghz is fine for me; above values generally don't work stable.
By the way, 1.2 ghz is almost enough for all games and operations, I did not run into that pushing apps for high oc's.
Regards.
1.44GHz, extremely smooth and stable!
Never seen an option to go above 1.54, but 1.54 works flawlessly so I've chosen 1.5 in the poll. (16gb i9000)

It's not the ROm it's the KERNEL who can oc, i adviise using XAN, hardcore kernels in 2.2. or gto's ginger kernel at 2.3 they are stable and 1280 i guess it's the limit not to warm up
But a questin what send me an undervoltage config, to 1300 if the gpu games work for someone at 1300mhz

I'm running Overcome Hermes 2.0.1 on an AT&T GSM Galaxy Tab, and I'm using SetCPU for both overclocking and voltage control. Seems like everyone has a Galaxy Tab that can be overclocked to 1.4Ghz except me. I want to join the party.
When I overclock to 1.4Ghz, for the most part everything runs fine, but when the CPU really gets stressed I get crashes. This has forced me to disable the 1.4Ghz step. This is despite the fact that my CPU performs like a champ otherwise, and I've managed to undervolt all the steps except for 1.2Ghz by quite a bit.
Is there a way for me to give the 1.4Ghz step a slight voltage bump to improve stability? SetCPU doesn't seem to offer an overvolt option, is there a way to edit a file and manually change the voltage? Where are these voltages for the overclock steps being read from in the first place?

If you do a quick search, there's a voltage control app floating around these forums.. voltage_control_gt.apk i think..
Donate version of voltage control supports over volting. Bear in mind increasing boltage doesnt necessarily mean more stabilty at certain clock speed.
But it does mean a higher chance of ruining your motherboard.
Hey does someone know the overclock configuration that was posted on the Overcome page once? I'm running on Overcome 4.1 with the belonging Kernel which allows me to get to 1.6ghz (theoretically) and I'd like to overclock to 1.2ghz.
I'd be very grateful if you could help me
Edit: I found this http://forum.xda-developers.com/showthread.php?t=1036020 but does this guide also apply to Overcome 4.1?
Just use Voltage Control or SetCPU. It's really not that hard at all. Just be careful with your voltages-overvolting will eat your battery more but may allow you to reach higher frequencies, and undervolting may get you better battery life but may make your tab unstable.
As a reference, I have my Tab running at 100-1.4 with smartassv2 and stock voltages on the Overcome 4.0 kernel.

for those who also have problems with overclocking and for
the newbies (like me =-D) I found this page which describes the usage of shedulers
and governors http://forum.xda-developers.com/showthread.php?p=19846297
IO Scheduler: CFQ
Governor: Smartassv2
At least that's what I use on my phone. I just left everything alone on my tab.

thanks, you helped me a lot ;-)
I'm using Voltage Control on 1.3ghz with stock voltages on smartassv2 and deadline and it runs pretty stable
Thanks, useful tip for me too.
I use SetCPU
OC max 1.3GHz, min 100MHz
-75mV from 100Mhz --> 1.0GHz and then -50 from 1.0GHz to 1.3GHz
PLUS various profiles to set max to 800MHz whilst screen off etc etc
that's exactly the same that I did =-D=-D=-D
That's pretty much what I have. OP, sorry I couldn't answer your PM, my tab is currently bricked and I haven't had the chance to recover it.

yea I have time =-D that's not so important, just make sure your tab runs again ;-)

This is what worked for me as well, just don't check"set at boot" option till you've tried that speed for a few days and you config proves stable.

Haha, I did check that option when I foolishly set the OC max to 1.6GHz
...I was just able to uninstall between one of the many lopping reboots
Anyway all, sorted now. In fact I have reverted to stock voltage for 1GHz up to 1.3GHz because playing Trial Xtreme2 would cause a reboot when I'd exited the game - seem's all ok now *touches wood*
Hi, I'm tempted to push CPU beyond current 1200MHz, no Undervolting. I want to do a survey on what CPU frequency settings and UV hold you for daily use. :silly:
I'm currently using 1.3GHz/368MHz with smartassV2 governor. Good performance and good battery life on IceColdSandwich 8.2. At 1.4GHz or higher, it's unstable and the phone freezes while the screen is powered off sometimes.
