Why do you want to OC to 1.9?
Sent from an ice cream sandwich

For me the 1.9 ghz kernel is a bit unstable for every day use . But oc at 1.5cm kernel works much better and 100% sable and battery friendly if you use profile in setcpu.

Unfortunately, that varies by phone. Mine becomes unstable and 1.5GHZ

I have to say. If you gotta ask dont do it! Make sure you setup good profiles for heat or you run a serious risk of frying your phone! Good luck some people got lucky and have no problems running 1.9. My phone has no problem with that speed until for some reason i have yet to discover somthing makes it heat up at random times. After that happened a few times i decided 1.5 is plenty.

I thinks it's underclocked @ 1.9Mhz

Root the phone
Install ROM Manager from the Android Market
In ROM Manager, flash Clockworkmod Recovery
Also in ROM Manager, backup ROM ("nandroid" backup)
Download the kernel and put it on the SD card.
Flash kernel from Recovery
Get SetCPU or CPU Tuner to set the CPU clock
As already mentioned, if you want to OC that high, SetCPU profiles with temp failsafes, etc. are a must. You might want to start with lower CPU clock speeds.
If you need more guides on how to get this done:

The Wiki guide is considered the safest way to root:
http://forum.xda-developers.com/wiki/index.php?title=HTC_Vision#Rooting_the_Vision_.28G2.2FDZ.29_and_DHD

kernel manager has it.

Yeah, it does. Unfortunately for me, it's stable for less than five blazingly-fast minutes Guess I'll stay at 1.5!

I think for a phone that was clocked at 800, 1.9 is far too risky. I have no factual basis to say that, just seems like common sense.

^I agree^ That doesn't seem logical....

I can't see OC our phones to 1.9 being good on any level. Seems like were trying to push the hardware a bit too far.

Is that how people are able to get Quadrant scores in the 2000+? I can't seem to get that high at all. I have been using pershoot's kernel with CM7...but now on nightly #91- using stock kernel now. I have been cautious on trying out this one...

Why would you want to clock it down to 1.9 MHz when the stock speed is 800 MHz? Even an XT-8086 ran at 5-10 MHz. An 8080 (the year was 1974) ran at 2.0 MHz.....

Lol, i think he meant GHz, typo =P..
As for quadrant, my DZ easily hits an average of 2100+ when OCed to 1.3GHz using Virtuous G-Lite 1.0.2. I really don't trust those benchmarks though, as long as the battery lasts and the UI is smooth, I can't really complain.

Well...ok, I was just trying to make sure I wasn't missing a step. I am happy with my phone's performance, so I will not be concerned about that anymore.

Bravo! I can't believe nobody else caught that.

1.9Ghz will sometimes cause my phone to either overheat or crash. I have it set to 1.516Ghz on Pershoot's kernel.

Phone gets hot after 10mins of use!

So my phone keeping getting hot after 10 mins of use why? I am currently running liquid smooth aosp jelly bean 4.2.1 beta 2. Is it the ROM or what?

Is something driving up your CPU usage? The fastest way to check that might be to see what's draining your phone's battery using the usual methods.

I had same problem. For me the fix was getting LeanKernel 2.0.
4 hrs screen on time! Its the best for my phone. Since all kernels are device specific it might not be best for you.
To get it go to T-Mobile gs3 go to original dev and download lean kernel 2.0. Make sure its 2.0.
T-Mobile and AT&T work the same. If you use one of the other 4.2 ROMs on here I think Liquid smooth it comes with Lean kernel pre installed.

I would suggest to update to his latest version. It no longer RC.

If that kernel doesnt work for you, you can always try Ktoonsez kernel here:
http://forum.xda-developers.com/showthread.php?t=1756776
But for me personally, his kernel and the stock kernel that comes with Task's ROM always make my phone hot and battery drains faster. But many people report those kernels work great for them.

Keep checking your processor settings, on my phone, it kept over clocking and under clocking randomly. Even without me touching the settings. Or get a widget to help you keep an eye on your ghz.

My CPU is at 1512 maximum and 384 minimum and when I touch like an app or play with the phone it clocks at 1.5 and when its just sitting there it clocks at 0.3 is that what your talking about.

No no. Like it would randomly change the setting to 1.9/1.8 ghz max. Sometimes it would set the max to 1.1 ghz. I donno, it was weird. Maybe that's your problem, maybe not. Every phone is different.

The same thing happens to me. It's not really hot, it's just kind of warm. It only happens when I'm using the phone, when it's locked it sleeps just fine and keeps cool. Otherwise it heats up and drains my battery in the process. CPU Spy shows my clock speed switches between 384Mhz and 1.5 Ghz depending on what I'm doing. My CPU usage isn't consistently high, even if its at 10% it still does it, seems quite normal. I can turn off data, wifi, bluetooth, and location services, doesn't help at all. I've tried resetting my battery stats, where I charged to 100%, cleared stats, depleted fully, then charged too 100% fully. No different. The heat comes from the bottom of the phone, maybe closer to the right side about an inch from the bottom, it is not coming from the battery. My battery usage shows high usage on the Media process or the Android System process. Ending either of them does not help, so I'm assuming they aren't actually using the battery like it says they are.
I'm running Liquid Smooth 4.2 beta 2, same as OP, with leankernel 2.2. It does the same thing with KT kernel, I've tried undervolting but it persists. I've also had this issue running slimbean, Liquidsmooth RC8, and RC9. My battery was pretty good when I used to run stock, and it was absolutely amazing when I ran LiquidSmooth RC3 and RC5.

[Q] CPU runs mostly at 1600mhz when using 4.1.2 custom roms

I've tried Omega 10 with perseus 30.1, 31.2 kernel and my CPU runs mostly at 1600mhz. I used to think that problem was related to the kernel, but now I'm using ARHD 8.0 with its stock kernel and the problem is still existing. I have also full wiped even /sdcard, but it didn't help. I've used 4.1.2 stock kernel and perseus kernel 29.1 before, and the problem was not there.
Can anyone tell me what is the cause of the problem?
Thanks.

try using uneak v 1.4 kernel....and set the cpu slider to the amount of Mhz you wish...try using another cpu govenor.
i think you are using the performance gov.
i hope it could solve your problem dude

Thank you guy, but I've not change any settings such as governor (it was pegasusq all time)

Mine does as well, but yet battery life is still pretty good. I wouldn't worry about it, as when it's not actively doing anything it will quickly throttle down, not to mention the other cores.

You mean although the cpu runs mostly at 1600mhz, the battery life is still good and normal? If so, I will give them a new try.

No, as in it will complete the task earlier and throttle down sooner.

So... what speed do you want?

I think that is not normal speed as other people have. Normally it should run among several frequencies, but mine always run at 1600mhz.

Actually I don't get why people underclock their phone, if u do this for better battery life, why dont u buy a sucker phone and a big pack of juice?

[Q] kernals for GPU OC?

Hey. I'm using the rooted stock jelly bean ROM with KT747 on my i747m. I'm wondering if there is a nice stable kernal for the i747 on stock ROM that would allow me to overclock the GPU a bit. I got my phone stable 2.1GHz at 1250mV and now the GPU is really holding me back in NFS:MW, dead trigger, NOVA 3, etc.
Is 2.1GHz at 1250mV a good OC? I noticed the default voltage for 2.1 was much higher. I had it stable at 1240mV (tested with setCPU, antutu, stability test 2.7) and ran it all day without any problems but I bumped it up 10mV just to be safe.
Thanks.

GPU OCs have been proven to not help. It actually hurts sometimes.

That's definitely strange. How would raising clock speeds hurt/not do anything? That seems pretty ridonculous.

Any GPU Overclocking Kernels for...

I recently flashed the KT747 for a super fast 2.1mHz CPU overclock. But then after flashing I realized it doesn't overclock the GPU that much.
Are there any kernels that can overclock the GPU to about 700mHz?
-Thanks for any help!

Sorry for CyanogenMod 10.1 (d2att) nightly ROM.
Does the new SiyahKernel work with the ATT Galaxy S3 running CM10.1 nightly?

Ah stupid me I meant 2.1ghz or 2106mHz CPU overclock.

I don't think any kernels do GPU OC, because it has shown to cause more problems than it is worth. That's just what I remember KT saying.

Most custom kernels if not all already have GPU OCd to 450mhz
Over clocking the GPU on a GS3 is not needed and even with it over clocked, you wouldn't tell the difference. It also leads to issues and battery drainage.
The S3 doesn't need OC at all 1.2Gz with 2Gz of ram leaves no place for lag.

I haven't had any lag whatsoever at any point that I've had my S3. Try reflashing your rom and completely wiping. Also try a different kernel and kernel settings.
This phone shouldn't lag at all. Maybe a little on TouchWiz but never on AOSP

My s3 lags at 2.1 GHz too. Try it at 1.6 or 1.7 GHz or change governor settings to a faster ramp up one.
