Overclock

[Guest starkos]

Got it running on my 2.1 rom (0x25/710Mhz).. Without JIT I got about 3 in linpack, but with JIT I just got 4.942 which isn't too bad for Eclair lol :lol:

[Guest flip360]

wow man i have 5.002 MFLOPS in linpack hahaaaa :lol:

Nice one gushty and kallt, i see 528Mhz (which we replaced) in SetCPU, is 710Mhz the running frequency?

cheers

Yes. For other freq's, reverse-calculate it: When it is 528 MHz, it is really 710, so 245 is 245/528*710.

BTW, I highly recommend to pull down the lower limit to the lowest possible (122 guess, it is really itis 164, it saves battery.

So do you reckon the processor/board can sustain the overclocked speeds without damage then, e.g daily use?

I don't think it damages the system, but we shall see how much battery it consumes, and how warm the pulse will be.

BTW JIT and OC together made Pulse 2x faster than factory default - if we remember it is somewhere arount 2.3-2.6 Linpack

What kalt did is exactly that:

- You open acpuclock.c

- Search for acpuclk_set_div

- Delete the whole function

- Insert the replacement code kalt posted here

- Save

- Build kernel

With 25 Linpack is above 5 :lol:

This only goes up to 528MHz....

Guess just see what happens then. Looks like it improves Neocore results as well, with sound turned off I used to get about max 26.7 and I just got 28 lol! Although it does seem to fluctuate quite a bit in the 27's so not too stable...

yes, it looks 528, but it is 710.

[Guest flip360]

i just got 7867ms in setcpu`s long benchmark (it was 10000 and upwards before) :lol:

[Guest Fusion0306]

I'm using flbmod_v2.0_oc_kernel.zip with jit and swap enabled. I don't see any difference in linpack with or without overclock. Am I doing something wrong?

that kind of OC seems to be not really effective. A guy from the pulse mini section found a better way - you find a quickly built TEST version here in this topic.

I've been looking through this thread but can't seem to find it :lol:

Edit: Found it, but I don't know how to compile kernels. A flashable zip maybe?

Edited September 26, 2010 by Fusion0306

[Guest flip360]

just flash it through fastboot

it is in page 10, name is new-boot.img. you can flash with fastboot.

[Guest Fusion0306]

Flash what? The boot.img from the pulse mini forum?? B)

Oh, ok, thank you :lol:

Newbie question: how do I use fastboot? Do I use: flash <partition> [ <filename> ] with boot_eclair.img, or I use flashall (not likely). If first option, what will be the <partition> name?

Thanks!

Edit: OK, got it! Sorry for the thread disturbance. You have a nice flight B)

So how's your results on Eclair(mine is on flb mod 1.3)? I don't understand, I flashed boot_eclair.img (from pg. 10 here), using SetCPU with 760MHZ max, using swap file with swapper2 and also enabled JIT in build.prop (don't know if this really matters if < Froyo?!?) and I still can't get better results:

Linpack: 2.19

SetCPU Long Bench: 11735

Anyone got this better?

[Guest hadley]

Yes I have results in the 8000s with the boot_eclair.img using flb mod 1.6b.

By the way if SetCPU gives you a choice of 760MHz, then your kernel has the wrong (cosmetic only) overclocking modification.

If you have properly installed the boot_eclair.img then SetCPU will only go up to 528MHz. But your pulse will be running faster.

I should mention that with this overclocking kernel and SetCPU on 528MHz, Google Navigation crashes (reboots the phone) within a few minutes.

On the stock FLB Mod 1.6b, I can run Google Navigation often for an hour or even two before it reboots.

Does SetCPU have some feature to associate a CPU frequency with a particular app? That way I could always lower the frequency when using google navigation.

You were right! I didn't flashed it properly! Now I've got 8500 and 2.9. Yuhuuu!

Thanks!

[Guest Simon O]

Thanks guys. I've updated the github with the new overclocking changes and I've removed min/max until BB can figure out why it's not building with it enabled.

[Guest Simon O]

I think the next step now would be to use this information to add additional speeds to the kernel which display correctly. I'll take a look at the code and see if I can work out how to do it.

[Guest lilim_ac]

yes.. now my linpack score 4.8 and my quadrant score 295

You propably could add a couple an extra 528000 line and change nothing except the 528000 number then change this line:

if(hunt_s->a11clk_khz>=528000) {

to this:

if(hunt_s->a11clk_khz>=710400) {

If you want to you could propably add some more steps between 528 and 710.4. Just combining the cosmetic overlocking with some code behind the scenes doing some real overclocking. :lol:

I plan to try something like that on my U8100 today although I'll stop at 691200 as that seems to be my upper limit.

In my case that means it'll look like this:

/* 7x01/7x25 turbo with GSM capable modem */

static struct clkctl_acpu_speed pll0_245_pll1_960_pll2_1056[] = {

		{ 0, 19200, ACPU_PLL_TCXO, 0, 0, 19200, 0, 0, 30720 },

		{ 0, 120000, ACPU_PLL_1, 1, 7,  60000, 1, 3,  61440 },

		{ 1, 122880, ACPU_PLL_0, 4, 1,  61440, 1, 3,  61440 },

		{ 0, 176000, ACPU_PLL_2, 2, 5,  88000, 1, 3,  61440 },

		{ 1, 245760, ACPU_PLL_0, 4, 0,  81920, 2, 4,  61440 },

		{ 1, 320000, ACPU_PLL_1, 1, 2, 107000, 2, 5, 120000 },

		{ 0, 352000, ACPU_PLL_2, 2, 2,  88000, 3, 5, 120000 },

		{ 1, 480000, ACPU_PLL_1, 1, 1, 120000, 3, 6, 120000 },

		{ 1, 528000, ACPU_PLL_2, 2, 1, 132000, 3, 7, 122880 },

		{ 1, 691200, ACPU_PLL_2, 2, 1, 132000, 3, 7, 122880 },  

		{ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, {0, 0, 0}, {0, 0, 0} }

};[/code]


Not sure if you use the same clock array as the U8100 but you could either add in all as you've done before or add different numbers and figure out which one is the one used.

which version of google navigation do you have installed? did you try the newest one too?
