Those who are overclocking, what settings are running stable for you? I seem to be able to hit just shy of 1.2ghz. Does changing the vsel of slot 3 help with stability? In general, does increasing the vsel setting help with stability (but hurt battery life)? I'm trying to understand what changing that really does.

Thanks!

Yes, the vsel translates to the amount of voltage being sent to the CPU. So if you up the VSEL you will be able to overclock higher but the battery draw will be more significant.

Awesome, thanks. what settings are you using?

So, after trying various methods and values for overclocking this is where I'm at:

- Running on SCV5.2 -
At first, I was just doing some adjustments using Terminal Emulator through /proc/opptimizer.. bumping it up from 1122 to 1175 or 1180, but I kept getting freeze-ups (it would just lock up, sometimes self-rebooted), especially when testing in antutu (or even just using boat browser, or flipping b/w apps quickly).

Then I moved on to Milestone, and boosted slot 3 back up to 1122MHz, 61 vsel at boot (after a short test), and started to play around with different values.
I gently nudged it up to 1150 and kept it for a few hours with moderate usage and an antutu test or two.. then up to 1175 for a couple of hours and tests..
Below are the results of my best benchmark so far (finally out-performed SGS2!!)
I think the SD card results were a fluke - have never been able to repeat the results (had SD-Booster set to 1824 for my Class 4, 8GB card)..

Still can't safely get to 1200..
These are my current settings, and they seem pretty stable:
slot 3: rate=1175000000, vsel=61
slot 2: rate=900000000, vsel=58
slot 1: stock (600M, 43)
slot 0: stock (300M, 26)
gpu_opps: rate=384000000

------
EDIT: just moved it up to 1188 and let it sit for a few minutes - and it just froze into a stuttering reboot trying to open CPU Master Pro! Starting over... Am I doing something wrong, or my system just can't handle it??

Sounds like your phone just can't do it. A lot of these chips can't actually reach 1.2ghz, but most can get close, 1175 seems pretty good.

Always take SD Speeds with a grain of salt.

Yea, i don't think my phone can do it - anything over 1180, it eventually freezes...
and, i did manage to get the SD read/write speed scores up to 150/192 once again - but yea, those scores jump all over the place depending on when you run the test..

I'm done with this overclocking business for now... the phone's fast enough as is - it's got much better performance then my wife's stock rooted 2.3.6 A2 - her phone averages 5100ish in antutu and lags a lot when playing angry birds, while mine gets 5700ish and only lags once and a while, usually while playing world of goo..

Mine got up to 1199 it would reboot a couple of times and when i tried to go to 1200 it would freeze like yours. So you aren't the only one with the sad news

I can go up to 1220 mhz fine. Here are my settings. Using milestone overclock on schv5
echo 3 1220000000 1390000 >/proc/overclock/mpu_opps
echo 2 1000000000 1365000 >/proc/overclock/mpu_opps
echo 384000000 > /proc/overclock/gpu_opps

If anyone wants to try. Stable for now, not a single crash.

I can go up to 1300 mhz .
but 1200mhz is much more stable
Here are my settings.

echo 3 1200000000 1220000 >/proc/overclock/mpu_opps
echo 2 1000000000 1100000 >/proc/overclock/mpu_opps
echo 1 650000000 1000000 >/proc/overclock/mpu_opps
echo 0 3000000000 900000 >/proc/overclock/mpu_opps
echo 384000000 > /proc/overclock/gpu_opps


echo 3 1200000000 1220000 >/proc/overclock/mpu_opps ->
echo 3 1233000000 1240000 >/proc/overclock/mpu_opps ->
echo 3 1250000000 1250000 >/proc/overclock/mpu_opps->
echo 3 1300000000 1260000/1270000 >/proc/overclock/mpu_opps
(i forget)

there may be some terrible grammatical mistakes,English is not my first language
