Has the w540/w541 bios throttling bug been fixed ?

#1 Post by hhhd1 » Tue Apr 16, 2019 7:50 pm

the w540 and w541 both had throttling bug due to bios, has any of them been fixed?

it is where the cpu gets stuck on 800mhz for ~2 minutes due to temperature, and it sticks there until the temps are down to 60c, unlike normal intel processors that throttle allot more reasonably by default.

https://www.notebookcheck.net/Lenovo-Th ... 450.0.html

"We can, however, see a drastic clock reduction of the processor to 800 MHz under maximum load (FurMark and Prime95 simultaneous) for the CPU and Nvidia GPU after 6 minutes. After that there is a continuous fluctuation between 800 MHz and 3,400 MHz, which corresponds with the CPU temperature. You will have to live with 800 MHz for 1-2 minutes as soon as HWinfo shows 99 °C."

I doubt it.

The W540/W541's BIOS change log doesn't even seem to mention any sort of throttling in it, so it is very unlikely that it has been fixed.
