my m17x r4 does not allow to change tdp<!-- google_ad_section_end -->

 

<!-- google_ad_section_start -->hello i am in the dark TT.

 

i am trying to oc my 3820qm and i've done it. But i want to keep the turbo mode more than 56sec(long power timewindow).

 

i have done everything to solve this on my m17x r4.

 

i've changed bios from a05 stock and a05 unlocked to a11 unlocked and a13 stock, and even installed every version of xtu and TS.

 

The problem is it screen looks like tdp is changed in the bios, xtu and TS.

 

However cpu never uses more than 55w and then after like 56sec it throttles down to 45w(that is 3.4ghz)

 

i have disabled msr lock, changed short/long limit to 75(and even higher) and changed timewindow to 56sec(and higher too). But nothing seems to help me.

 

People say they can run r4 at max turbo clock all day and i also have seen one of those screenshot.

 

For me, it works as if msr lock isn't unlocked.

 

Is there any way I can solve this? or is it just non-XM CPU's capability or even m17x's capability?

 

Hello godfafa . How did you disable the MSR lock? I am trying my best to edit the RAPL power limits using the MSR reg 0x610 (MSR_PKG_POWER_LIMIT). I am using a Haswell processor. I have tried using the wrmsr command with root privileges. I also tried using the intel power_governor tool but that too did not work.I have also tried using the /sys/class/powercap/intel-rapl files to change the power limits but it throws error when i commit the changes. Lastly, I tried to change the lock bit (Bit 63) using the intel_rapl module. I used the rapl_write_raw_data function to try and edit the lock bit but that too didn't work. It does not throw any error so I am quite stuck. I wish to regulate the powerlimits freely in user mode. Please guide me. Thanks!
