here you go: Short guide about Overclocking/undervolting on Doomkernel v9

Running Stock 4.2.2 with Doomkernel V9

Stock:

CPU 1728mhz (all4 cores!)

CPU 1728mhz GPU 533mhz

CPU 1728mhz GPU 487mhz

i can't guarantee the GPU did not throttle, as i had it in the Fridge, it was verry Cold, but the GPU gets REALLY hot and CPU on 1.7ghz is also not cool. but it still showed 487mhz at the end of the benchmark and 533 as max Clock! So i guess it just wasnt fully loaded but did not throttle!

But if you ask me, 533mhz is unstable! might only be my phone, someone else has problems with GPU OC on 533mhz ice cooled ? ^^
[Xperia Z Original Android Development] dron39:
No, i also have this issue. GPU OC always going down, and DooM know it and try to fix this thing (as he said before :) )
[Xperia Z Original Android Development] xNAPx:
lol so i have some problem here because my score is just 3k. in kernel tuner my cores always deactivate themselves and cpu gets 1,2ghz frequency so i really don't know how to do that
[Xperia Z Original Android Development] :
Really sick kernel, I got 8437 on Quadrant with 1944MHz but I have some questions,

What is a good and safe clock speed for everyday usage? I can't imagine max clock speed beung good at all times I now have it on 1600-1800 governor: ondemand.

I also read about GPU overclocking, how do I archieve this? I can't find any sort of app in the Play Store.

Thanks in advance
[Xperia Z Original Android Development] [NUT]:
Really sick post... Quoting the OP... Please remove it...

Search this thread on how to oc the gpu, it's in here multiple times. DooMLoRD has also posted a small app to check the gpu frequency.
[Xperia Z Original Android Development] Haldi4803:
There is a difference between thermal throttling and GPU not working correct, if you take Qualcom Trepn Profiler you can see the clock going down from 487 to 400mhz when you're testing without extra cooling! If you set 533mhz and put the phone underwater you can see the 533mhz staying for the whole benchmark (well.. if you have a SHORT benchmark xD that GPU is so hot, even with 4°C Water Temperature after 30sek-1min its going to throttle)

Edit:

Used Trepn Profiler on Antutu 3D (only 3D) Stock settings:

Full Trepn CSV Log:

http://pastebin.com/rbWJDzPH

As you can see the CPU stays on 400mhz for 46 Seconds. Enough for a full run! (didn't meassure it, but it was around 30-35 sec)

And now on 533mhz GPU OC:

Full Trepn CSV Log:

http://pastebin.com/fP8Qirba

Excluding a few strange drops (really only a few) the GPU stays on 533mhz for a whole 70 seconds! also CPU did not throttle down.

Still the results in Antutu are worse than on 400mhz or 487mhz! thus: 533mhz is to much! our GPU can't handle that! Its not only Antutu, Every GPU Benchmark i tried reacted the same.

note that i had the phone in the fridge the whole time. befor testin 533mhz CPU and Battery Temp were equally! This screenshot is made after the Benchmark (70sec full power running).

The Only way of Fixxing this would be to increase GPU Voltage, which would result in a way higher Powerdrain/heat production, and would cause the phone to throttle down even faster as it does now.

If your CPU speed get reset to 1.2ghz then that is because of thermal Throttling! You should continue your test in Sibiria or somewhere else where it's really really cold to continue Overclocking!

how can i activate all 4 cores? its not showing on TricksterMOD app anymore.
[Xperia Z Original Android Development] Haldi4803:
get Kernel Tuner *root* an go into CPU settings, that activates all 4 cores. if you tab out of the app instead go back it will keep them active!

v10 must be epic release!

my question is that I dont seem to find other kernels out there, so all the Custom Roms (with custom kernels) have a modified version of DooMKernel?
[Xperia Z Original Android Development] Mr.Dadulka:
Currently - stable for a day, there are still some limits to go lower. By I think there is not a reason.

192 MHz - 675 mV

384-486 - 700

540-594 - 725

648-810 - 750

864-972 - 850 (according some other thread 864 MHz might be unstable if lower)

1026-1242 - 950 (1242 mHz is my max freq.)

1296 - 1000

1350 - 1025

1404 - 1050

1458 - 1050

1512 - 1100

[Xperia Z Original Android Development] DrKrFfXx:
So I was having a dump while thinking about how to save battery aside from undervolting the cpu, and suddenly it ocurred to me, what if we could undervolt the antennas? Is that even possible through kernel or at all? Is the power output directly related to signal strenght, meaning lower voltage, lower reception? Any thoughts?
[Xperia Z Original Android Development] mamenvn:
Hi Dadulka,

When i set 192 MHz - 675 mV my phone to reboot
[Xperia Z Original Android Development] [NUT]:
That was to be expected... your CPU will have other characteristics as his, you should still look for your optimal setting by stepping down one unit at a time...

You won't be able to know what production run produced your CPU or GPU for that matter and what revision of the model your phone has, so treat the UV lists people post not as a 'working example' that you can apply to your phone but try and find your own bottom level!
[Xperia Z Original Android Development] Lemagex:
I would love to see that happen but i doubt it'd do a significant difference in battery life. Also it's amazing how many good ideas come to mind when one takes a crap... :eek:
[Xperia Z Original Android Development] bbeanss:
I haven't got a problem with bootloops or anything, but my undervolt settings won't stick on boot using SetCPU and IncrediControl, any ideas guys?

What is the point in this kernel? What eve is a kernel?
[Xperia Z Original Android Development] gm007:
What is your question?:D
[Xperia Z Original Android Development] sea2605:
Maybe he wants to know about exclusive features of this kernel: underclocking and -volting e.g.

...or maybe he wants to say something deep like "Life is so meaningless... why do we need kernels? All we need is love! Lets pray all together...ohhh (doom-)lord..." ;)
[Xperia Z Original Android Development] xNAPx:
Undervolting is ok but i'm more interested in overclocking, even because if the cpu keep itself safe underclocking itself how can i be sure that my cpu is working at max stock clock Undervolting it? Maybe Undervolting it caused a lower working frequency and so how can i be sure that the less battery consumption is due to its undervolt and not its underclock? Hope i have been clear (I'm not English:| )
[Xperia Z Original Android Development] elspanish88:
Get a widget that shows you the cpu speed etc and do some testing... Do a day where you only under volt and then a day where you only under clock and a day where you do both then compare the screen on time etc
[Xperia Z Original Android Development] xNAPx:
Which widget do you suggest to check cpu frequency ?
[Xperia Z Original Android Development] elspanish88:
Kernel tuner has one but you have to tap it to refresh... I don't use one personally I've UV'd a little bit this morning phone seems stable and battery is a bit better so I'm happy enough not to need to look into it
[Xperia Z Original Android Development] Mr.Dadulka:
Q about UV:

My CPU more less cycle between 192 MHz (675mV) and 1242 MHz (950 MHz).

Others freqs are not almost used. Gov whetlay, now ondemand.

How should I make the system use more other frequencies? Set something or kernel behaviour?

Swyped from my sweet JB powered Sony Xperia Z.
[Xperia Z Original Android Development] Dsteppa:
Do nothing, just be happy that not all frequencies are being used, that would drain your battery faster. Let the CPU handle that by itself.
[Xperia Z Original Android Development] viper001:
On that note... I've been wondering why there's a lot of them, while most are not used?

Is it really better to have a lot of steps or have just maybe 7 or 8 of the most used ones?

I have no choice but asking here as it's the only available customisable kernel for XZ (I use advanced stock one until now) :

I don't like how strong and noisy is the haptic feedback/vibration on the XZ (plus since it falled from my bed few days ago the noise is even more annoying) , so I'm looking for a solution to reduce strength for both haptic/vibration. I tried few apps on the market without results and got in touch with some of their dev, but after some explanations it seems like it's kernel related setting.

Is this one customisable regarding these issues ?

Thanks for help, infos, links, etc.

Can someone please overclock it to 1.9, set the governor to performance, turn their screen off and wait 20 seconds?

[Xperia Z Original Android Development] xHok:
So I tried it and I got reboots with only 1.8ghz and above. I waited only 30 sec tho
[Xperia Z Original Android Development] xNAPx:
can someone please tell me which is the best governor and I/O scheduler to have great performance (obiuvsly not the performance governor) and a good battery menagement?
[Xperia Z Original Android Development] Haldi4803:
That setting is called Governor! ..... why did you change governor when you don't even now what it does? Don't you think thats reckless ?

huh ? Care to explain ? Just a link to a topic will be fine :) why would not switching frequencys save battery ?
[Xperia Z Original Android Development] *boy*racer*:
Thanks. Yeah I just tested again properly and it does seem to reboot from 1.8 onwards.

Isn't that strange though as it only reboots when screens off?
[Xperia Z Original Android Development] happily1986:
That's right.
[Xperia Z Original Android Development] xHok:
it might be a bug with a safety feature. but I use only 192mhz-1.3ghz so I dont really care :):)

[Xperia Z Original Android Development] Haldi4803:
So.... more about GPU OC..... tried out GFXBenchmark (GL Benchmark 2.7) today, was hot outside, used the phone for a while and made a run. 15FPS and score 842 because it could have throttled i put it in the fridge and redid the test still 15 FPS and score 841 so definitly no throttle. Because there might be a CPU limit i did overclock the phone to 1944mhz. still 15 FPS and score 843 so CPU is no problem at 1512mhz!

Then i overclocked GPU to 487mhz and had 17 FPS and score 945.

Because i wondered where this score comes from i made seperate Fill rate and Triangle throughput tests.

Stock Clock 400mhz, OC 487mhz, OC 533mhz!

As said before, 533mhz brings worse performance than 400mhz (Except the Fill rate!) And no the phone did (by a 95% chance) not throttle ! i had 2°C SoC temperature afterwards and -8°C Battery Temp!
[Xperia Z Original Android Development] sea2605:
Guys, I still wonder why faux clock wont show me the gpu settings... I'm already on doomkernel v9 and .423...
[Xperia Z Original Android Development] MrMmmkay:
Try AndroidTuner, it supports GPU overclock for XZ since I wrote an Support request for that :D.
[Xperia Z Original Android Development] Haldi4803:
and underclocked to 325mhz!

Strange thing is that i had to put it into the fridge to run 325mhz! When trying normally it always reset 325mhz to 400mhz! Maybe Thermal throttle is constantly active ?

Unlock bootloader before or after 10.3?

Hello, DooMLoRD.

I have enjoyed reading this thread and was planning on installing your kernel sometime soon. Now, I was just offered to update to 10.3 OTA and was wondering if I should do that right away, or if I should/must wait till after I have unlocked my bootloader? Currently my C6603 is locked but rooted and I have a proper TA backup.

I'm not really in the mood tonight to restore all my stuff after the full wipe that comes with bootloader unlocking.

If you unlock your bootloader you will not be able to update via ota,pcc,or sus till you lock it again.

Hello,

I hope someone can help me:

I am runnin gon Doomkernel v9 on 7.2 auras rom (423).

If I am setting the kernel (eg 192MHz up to 1512MHz), then after a reboot the settings are gone. He leans back in 1512 or 384 .. again

I tried it with Nofrills, SetCPU and other apps. By Ini scripts and boot settings.

I also re-installed with full wipe.

Can someone tell me how I can solve the problem me?

Thank you very much
[Xperia Z Original Android Development] m0b:
There is init.d file in RA 7.2 called "95ondemand" it sets min freq to 384 (and do some other things), you should change it or make another one. But new script should run after

95ondemand, call it 99cpu (for example)
[Xperia Z Original Android Development] dron39:
DooMLorD,

After reboot or starting my XPZ when it booting up i see for a half second "screenshot" from OS before. (for example apps menu, or home screen or shutdown menu) It displays before your DoomKernel Logo.

I haven't seen this "bug" before on your v04..v08.

How can i "repair" this. :) It is normal?

Hi Doomlord,

congratulation for this excellent Kernel. I am using Doomkernel v9 on auras rom 7.2. It is working perfectly smooth with no issues, except after doing a nandroid backup with cwm I am stuck on the starting screen with the floating colors. Any idea how to fix this?

Thanks!
[Xperia Z Original Android Development] deifel:
Are you sure you have no problems with v9 aura and doom?

Point times the kernel to OC in 1712 and 192MHz and reboot.

If the settings are gone?

---------- Post added at 10:48 AM ---------- Previous post was at 10:46 AM ----------

Thank you for your help.

I have found the script and deleted (for testing).

However, the problem remains. He does not mean more jetrzt from 192MHz to 384, but I imagine as to 1.7 ghz - then it is again changed to 1512 or just 1.2 ...

An idea of what that might still lie?
[Xperia Z Original Android Development] m0b:
This problem have been discussed already many times, its because of Sony heat control. Some Sony scripts and APKs decreases max freq to 1.2 (or may be lower) and when in became cooler back to 1.5. See the first post here.
[Xperia Z Original Android Development] deifel:
Thank you again:)

So is there any chance to overclock this kernel to 1712mhz? permanently?

I put in SetCPU or nofrills this value, but it resets itself again and again.

If the problem is with heat control, how can I permanently change then?

Thanks very much:good:

[Xperia Z Original Android Development] [NUT]:
I had this using Sony's own kernel too, I think it's the buffer from the gfx chip not getting cleared before the device reboots. It's a bit annoying but probably will get fixed at some point, either by Sony or by DooMLoRD :)

IF you would be able to set it to 1712mhz permanently, you would probably fry your cup and the hand holding your phone... Just be happy the overheating protection is there and ask your ROM chef for a fix.

[Xperia Z Original Android Development] [NUT]:
Well... sometimes the hardware they (Sony) purchase gets an update itself (a new stepping), while the overall characteristics are the same, the devil might be in the details, causing these problems... Or it might be a bug in a delivery of the 'same' chips from a different manufacturer caused by their manufacturing process, just like the 2 different displays to be found in our phones.

But to be honest, I'm stabbing in the dark here, I really do not know why.

Nope, I'm using the stock .423 myself.
