Ok can anyone else confirm. I used cpu spy and other variouse kernel tuners to see that all 8 core will not go past 1.5 GHz. I am on the tmobile 920T and others are not going past 1.5. I am not coplaining about performance but if the exynos cpu is not putting out then we have a problem.

It's only showing the A53 cores speed and not the A57 cores.

Look at the better battery stat screenshot. Time in state for all frequencies has a highest level on 1.5ghz only.
I did benchmarks too and still not passing 1.5ghz.
There is no problem ,CPU spy cannot read the frequency correctly for a BIG.little CPU
It shows frequency for little([email protected]) cluster only ,not the BIG(A57) cluster which goes up to 2.1Ghz.
P.S Hopefully you understood this

This^^^
Side Note:
I do believe its big.LITTLE though? Or am I off base. Could've sworn it was this way though. One of those odd things I remeberd because of the slight irony.

I hope this is 100 percent true. I even looked at trickster mod and it wouldnt let me set the frequncies higher than 1.5 either.

I was trying to figure out which scheduler available in 'pimp my cpu' worked best...
my results were inconclusive, but I figured I'd post them anyway, maybe a stats geek will know better than me.
methodology:
set cpu scheduler using PMC, save settings as boot. reboot. using quadrant, run 5 benchmarks. repeat for each scheduler.
test enviroment:
LG G2x
rom:
Bionix 2 with Trinity kernel.
pimp my cpu settings:
max 1500 Mhz
min 500 Mhz
all speeds -50mv.
Results:

anticipitory 3275 4004 4103 4099 3876 3871.4

bfq 4321 4268 4035 4008 3579 4042.2
Cool, nice for you to take the time to benchmark the I/O scheduler. I always knew BFQ is one of the best I/O schedulers available, that's why it is usually the first technology I introduce with my custom kernels.
I noticed that when using bfq launcher pro was smoother but my phone would go up to around 80% of CPU usage.
So basically bfq has a smaller threshold and uses more of the cpu's power even for light tasks and that's way it benchmarks higher.
Hope that made sense lol

Anyone know if antutu supports dual core?
Because the hummingbird's GPU considering the cpu clock speed is at 1ghz, antutu reports back 1106, now if i oc'ed it to 1.2ghz , i bet this I9000 could perform just as well as the new nexus on certain games

^^ my phone, Samsung Galaxy I9000 (16gb version, 4 months old, came with 2.3 now on 2.3.3, now my 3D graphics score is 1106.
Here is now the
http://www.youtube.com/watch?v=w4a-sphr07c
above is the new galaxy nexus, which has a dual core, it has a faster cpu, by rights, it should really own a phone as old as the i9000 fair to say.. but, if you break, it down you'll see that the nexus's GPU power only gives it's a slight boost, 3D 1226 on the galaxy nexus, and on a humble I9000 GS, we have 1106..
Now what gives the impression of a superior score, is of course, double/triple the memory and significant IO/read/writes.., when it comes to Asphalt 6 on the I9000 vs I91000, there's really not much difference on that game...
So the differences between an i9000 and say a galaxus nexus, please it can't be just triple the memory, a faster clock frequency, and a slightly more powerful GPU? because the difference after you OC the hummingbird processor of how the GPU (specifically GPU here) performs....
I was lead to believe the GPU in this was significantly better than the I9000's?
You sure you have the original galaxy s2 the 2d score with exynos and Mali should be around 900 something. The t-mobile version has a snapdragon s3 processor.

I purchased SetCPU about two weeks ago. I stopped using it because my phone started to get choppy, so i disabled all my profiles and disables start at boot. I kept the widget alive cause i had a free space on my widget screen but since i installed that, i see that the CPU stays a lot at this speed. I rarely see it at 1500mhz. Not sure if its normal

could be that widget isn't refreshing because app is no lo.Ger installed, which is probably the case
yes it is refreshing because the temps keep changing, the app is installed, i just disabled it from managing my cpu but its still there. also, if you knew how setcpu works youd know the max is the highest frequency allowed and the low, the lowest, it is not by any mean a indication of current mhz, so something keeps changing my cpu profile...but what?

You can check your CPU levels with the app cpuspy on the market.

next i see into system information uses only one core
i try disable mobile data but still only one core. next i try fly mode and there are 2 core. but when i try disable fly mode and enable again there is only one core.
when i reboot phone i have 2 core about a few minutes
and score is better
what is wrong?
The second core activates when needed so since you were using the phone it 'came alive' thus giving you the better score.
but when i run test, secound core is needed but still run only one. when i work on phone and look into quadrant still writes only one core.
I tried to run the test 5 times, but still is low score

You're new here, aren't you?
Don't use quadrant. It's crap, and has been for a long while. And also, the "new" scores are since it was updated for multi core, they are much lower all around.
our CPU is built to only use 1 core most of the time. But when a threshold on cpu0 is reached, cpu1 activates until a lower threshold is reached.
And no, it's not good to force the 2nd CPU to be online always, as it actually makes the phone slower.

what's the best setting for overclocking to 1400mhz without having reboot.
Raise voltages until it's stable. In rare cases, you may need to lower them. If none of this works, the SoC in your phone is too imperfect to clock that high (it wasn't intended to anyway).

okay, thanks for reply. i'll try it.

Thanks for sharing those infos...
May i ask for some more?:
System details [rom, kernel]
What app is the one you use on this screenshot?
what theme do you use?
Battery life with this OC?
Thanks a lot
1. rom : http://forum.xda-developers.com/showthread.php?t=1399035
kernel : http://forum.xda-developers.com/showthread.php?t=1036996
2 hold volumen down button + power button for 2 secound in same time..
3. http://forum.xda-developers.com/showthread.php?t=1531222
4. i think it same as 1000 mhz "OC" , because i have same voltages for 1000 and 1320 mhz..
i meant what application are you using to set the voltages... sorry i wrote the question the wrong way
