Overclock

[Guest gusthy]

Hi everyone,

Since BB seems to be busy, I tried to look around overclocking.

The question is if anyone knows which values to use in acpuclock.c ?

_I GUESS_ this line:

{ 1, 528000, ACPU_PLL_2, 2, 1, 132000, 3, 7, 128000 },

Maybe you can change 528000 (528 MHz) to 600000 (600 MHz)?

Yes, but it is not dividable by 132000, so I don't know if it will work?

Hmmm, then I'd say 660000, but that's a way too much.

What if we change the multiplier (if it's named that way) to 120000, and the freq to 600000?

[Guest gusthy]

There is an other possibility, now I try this:

If this fails, I will go back to that solution with the table.

Just wondering if Overclocking the CPU when we can't improve cooling is a good idea?

Not sure how much play we have in temp when the phone is running at 100%....

Good question, we shall see.

Hopefully the phone cannot be killed, since it has temperature sensors.

ARM processors generate very little heat and the small overclock they are given in some other devices don't increase this heat output by very much. Actually most of the heat is from the battery.

will really improve general performance with the memory bottleneck? mmm.........

It will only improve perfomance with applications that fully utilise the CPU. GPS applications, video players etc. With general daily usage you probably won't notice that much of a difference.

{ 528000, ACPU_PLL_2, 2, 1, 132000, 3, VDD_7, 128000, 0, 5, -1 },

{ 550000, ACPU_PLL_2, 2, 1, 132000, 3, VDD_7, 128000, 0, 5, -1 },

{ 560000, ACPU_PLL_2, 2, 1, 132000, 3, VDD_7, 128000, 0, 5, -1 },

You are right, the prototype from XDA is

Here The Soucre for 780

Like the code to extend the clocks.

It could work in Rom 1.5 version, and the change in the setcpu.c isn't needed.

But it needs to cooperate with SetCPU app, with the manual setting in setcpu.txt which in the root of sdcard.

By the way, the maximum is 800MHz. The highest clock could work but the performance is low than my expect.

Is it stable?

Would u please share the details of the modification? Thanks a lot

Just Like the 780 code to extend the higher frequency, then re-compile the kernel.

But it needs the SetCPU app from XDA to change the maximum frequency by manual.

It's very unstable above 600Mhz in CHT8000....

You don't need SetCPU. You can set the frequency via the proc fs:

echo 780000000 >/proc/cpu/max_frequency

(or something similar) and change /proc/cpu/scaling_governor to performance

echo "performance" >/proc/cpu/scaling_governor

Thus you can overclock your Pulse via a script, optionally even through the init.rc at startup.

If flibble allows me to, I'll add the new acpuclock file to his custom kernel (besides from MT btw :lol:) and add the appropriate settings to the kernel config file, to be able to disable overclocking.

wowowowowow, wait a sec, "besides MT"? PLEASE DO BOTH :)

[Guest starkos]

Will they be the same as those from the 780 source at xda or are they modified specifically for the Pulse? If the later could you please upload the files (in a directory tree so I know where they go lol) for those of us building the kernel our selves? :lol:

I'll test the Pulse with different clocks and see which one works best. After that I can upload a filetree with the needed files, but that is going to take a while. I'm pretty busy atm :)

Nice one, and no worries there's no rush anyway... :lol:

Codes on github, feel free to play with it :lol:

[Guest flip360]

can we have some kind of flashable zip for this updated kernel, for users that dont compile from github?

thanks

Hmmm, no new acpuclock.c is in github, BB, probably can you put it there? Then I don't need to spend time finding out everything...

The code on github is just the code from Huawei. I've changed nothing in it myself.
