[Xperia SP Android Development] Onawt:
I haven't decided yet. I run this custom kernel now for like 2 days. I'm still testing and experimenting.

Ignore my previous post btw about the benchmark scores. Antutu is really weird in testing. Frequently it fails the 3D test. Then I rerun the test. Then a score of roughly 40.5K comes out (seems somewhat too low for me). I go and check Kernel Adiutor and my CPU or GPU is all of a sudden down clocked to the stock 1728MHz or 320MHz respectively. Putting the frequencies back to 1998MHz and 480MHz and rerunning Antutu makes my phone shut down. I have to restart it manually. It seems either Antutu really can't handle the OC's or (especially) my CPU OC is unstable [MENTION=4724277]1300[/MENTION]mV voltage). I'll report back when I have trustworthy benchmark scores at the right frequencies.

EDIT1: After a run I got 41144 points in Antutu. Went into Kernel Aduitor to see if this score was accomplished with CPU @ 1998MHz and GPU @ 480MHz, and guess what... CPU was @ 1728MHz and GPU @ 320MHz. I still don't understand how Antutu gets the kernel to down clock or if it is a safety feature or something. I'm now in the process of rerunning the benchmark with max OC settings. This really confuses and irritates me.

EDIT2: 1998MHz @ 1300mV is definitely not stable. At least in Antutu benchmark. Antutu stress test (15min CPU load) survives perfectly fine. Geekbench 3 just runs fine with 1998MHz @ 1300mV, but for some reason my phone shuts down in Antutu benchmark with CPU at 1998MHz @ 1300mV. I'm going to test 1890MHz now and see if this is stable.

EDIT3: Since Antutu and the whole OC'ing keeps being weird. I'll hereby report my whole experience to you [MENTION=5727088]Tomoms[/MENTION]. Maybe you can help me.

So...I did wipe cache partition. The random stuttering and 'App X not responding' disappeared, but OC'ing is still a problem as you already guessed from my previous posts.

I boot the phone, changes made in Kernel Adiutor are applied at start-up. I wipe Antutu's data in the settings, so previous settings don't mess up my testing. I start-up Antutu and do a benchmark. After this different kind of situations can happen.

- Situation 1: Antutu finishes its benchmark, but the score is around 28K. It is this low, because it says "3D [unsupported]". Also CPU and UX points are lower than usual. This seems like an incomplete test, so I run it a second time.

The second time a result of around 40K comes out. This looks more like a valid score to me, so I check Kernel Adiutor to see if it has achieved those results with CPU @ 1998MHz (or 1890MHz) and GPU @ 480MHz. This is not the case. CPU is clocked at 1728MHz and GPU at 320MHz according to Kernel Adiutor.

-Situation 2: I set CPU and GPU clock speeds back to my preferred OC values and rerun Antutu. Now the following happens: either the same thing happens (a score of around 28K with "3D [Unsupported]") or it runs the 3D test, and right after that immediately reruns 3D test (instead of continuing with RAM test) and a score of around 40K-41K comes out. But again, checking Kernel Adiutor reports CPU clock speeds at 1728MHz and GPU clock speeds at 320MHz.

Could you please tell me what's going on? Thus far I can't get a reliable score out of Antutu. I don't know when the CPU and GPU are actually overclocked and when not.
