Binary patched kernels for Pipo models

[JayDee]

Pipo m9 wifi patched kernels ?

For rileyrom 2.2/2.3

[giouncino]

I use the kernel cpu1704 gpu600 ddr792 low voltages, the stability chart is very good on antutu and I get 19800 score on HD MODE. I also launched GFXbench, this is the result (I don't know how to interpret them).


Everything seems good, however, it happened 1 or 2 times that Google play crashed. Same for others applications downloaded on the black market ( so I don't know if it s because applications on the black market are unstable or not...).

Furthermore, the used of the "Browser" makes my tablet freeze with Hard Reset needed (2 times and I only tried twice, chrome works well). I flashed both this kernel and the RilleyROM 1.3 for the first time today. Do you know where does these problems come from?

EDIT: Sorry for this big pic, I don't know how to reduce it...

I think you could have reached the RAM frequency limit, try to install the kernel with ram clocked at 720Mhz (it is called "target" on page 3 of this thread or the one inserted in the following post), and check if you are still having problems.
It is also based on low voltages so you can save a lot of battery.
The difference in performance between 720Mhz and 792Mhz for the RAM is negligible.

1704/600/720 generated by the script gouncino package 1.1 low voltage

I'm pretty sure that most of you having problems with 1704/600/792 LOW VOLTAGE kernel, they are due to the RAM clock. 792Mhz is quite high and many tablets are not working well with such a high frequency.

Because of that here in attachment you can find the kernel 1704/600/720 generated by the same script gouncino package 1.1 low voltage but with the RAM set to 720Mhz.
kernel_cpu1704h_gpu600h_ddr720_low_voltages.zip

Try this, I think that this will be stable for almost everyone.
PIPO2000 and the others: this should have a GPU with lower voltages with respect to the kernel called "target" (present on page 3). I suggest you all to try this firmware. I think you could save at least 30% of battery wrt the stock kernel AND almost the same performance wrt the 1704/600/792 LOW VOLTAGE kernel.

As usual, any feedback is really appreciated!

Hi giouncino
thanks for this support, it's really very appreciated

Btw, neither of those 2 can boot on my tablet...

but it's not a problem I use the previous at DDR720 and runs smoothly.

Battery drain is still 10/15 % lower than stock kernel, to me.

PPS: Vellamo benchmark passed with no problem and with results 1198 HTML5 and 542 Metal. However I'm restricted now with access to some web pages (company proxy) so test might be not full and I have nothing to compare. Does anyone know results for Google Nexus 10 and Galaxy Note 2?

with the 1704/600/720 kernel i got 1770 and 572 in vellamo..

still none of the +50mv kernels did work properly, either causes a freeze of the first pipo logo, or crashes in use.. even the 1604/600/720 +50mv does not work at all, while the 1704/600/720low voltage is working fine... for me, it is the best kernel, high speed with excellent battery saving...

good job, g!!

Thank you to you all using my kernel. It is very interesting to see such different behaviours...
Probably there is something wrong somewhere on my kernel with +50mV. As soon as I can I'll check if there is something wrong in the scripts...
I'm very happy of the battery saving that modified kernels can assure.

[herrjemineh]

me too..

my cpu is starting with 1800 but not stable, crashes in every application...
ram with 792 not possible, same with gpu at 798

funny, how different hardware they must have used..

edit:

can someone explain to me, how one can modify that script? i have an idea which parameter to change, but i have no idea to change the script...

Also the one on my post #170 is not working for you?

Pipo m9 pro 3G

Is there any patched kernels for Pipo M9 Pro 3G.
Could not find anything spesific
Many thanks

pipo m9 wifi 1704/600/792 LOW VOLTAGE

hi gourcine just to say that your 1704/600/792 LOW VOLTAGE works fine on my tablet thanks!! ^^ and for the bench i do 21500 on antutu so there is not huge improvements in comparison with the 696kernel from dnkn but it seems a little smoother on games !!

For rileyrom 2.2/2.3

Didn't work for my m9 wifi, all 3 freeze at boot image.

It's very simple, you need to change the values in the tables at the beginning of the file (the values following "CPU_1704h" , "GPU_600h" and "RAM_792")

This evening I'll try to rise a little bit ONLY the RAM voltage. I suppose that for you the problem is still there!
Because with respect to the kernel "target" this one has lower ram voltage and lower GPU voltages.
I suppose that GPU voltage is not the problem!

Thanks, I appreciate your support but don 't want boring you. It 's time for me to learn how to use the Pearl script and jfhAnderson tool.
Can you suggest me some "how to" ?

Thank you!
