Overclocking and undervolting of Intel Z2560 in Android

[Vipin_A_]

Dear friends, I am trying to overclock and undervolt the Intel Z2560 used in Zenfone5 smartphone. Can you help me find the relevant code to do it. Where is the dvfs code available for it?. Is it even possible to overclock and under volt this processor. Please help Warm regards Vipin

Hi Vipin,

I'm not aware of any existing method to do so. You can reduce the clock speed if you have root access but this is all what I know is working. 

If you want to do experiments we have a program called Mobile Development Kit (MDK). At the moment only two Dell devices are supported. For MDK supported devices you can unlock your boot loader and you get full sources to recompile the OS. 

Even if you have your own Kernel with the  required patches for dvfs I'm not sure if the firmware will support overclocking or undervolting. So it might be a lot of effort without any result. 

Thanks,
Alex

Thank you Alexander for your response. I am already rooted, but I can't reduce clock below 800mhz. Is it possible to enable it in kernel to reduce below the factory set limit of 800mhz. Bootloader is already unlocked and we have access to kernel source provided by the company. But unfortunately nowhere can we find codes to access CPU frequency. Will acpi settings help? Warm regards Vipin

Hi Vipin,

if you are working directly with an OEM and receiving unlocked devices and sources from them you should ask your questions to Intel through this OEM. The Intel Support team for this OEM knows the configuration of the device and firmware.

Unfortunately this forum might not really help you. 

Thanks,
Alex
