Windows 10: Processor throttling under load

Good Afternoon,


Since installing the 20h2 update my CPU i7-8700k throttles down too 0.78ghz under load. This happens gradually, but is not linked to the temperature as the chip us only hitting 31oC and is water-cooled, I've never had this issue before.

My CPU is OC'd to 5.0ghz across all cores and I have tried to force the chip not to clock down by changing the AVX offset to 0 in the BIOS.


Is there anything I can do to get around the issue or do I need to roll back my windows version?


Many thanks,


Chris

Processor upgrade

The process is just as bobkn described.

To avoid problems with the flash, do the following:

• Download the 3 files you need, and save them to an easy to find location - Desktop, etc. You will need BIOS version F32, BIOS version F50, and the EC FW update utility.
• You will need a blank USB thumb drive (nothing on it). The thumb drive needs to be formatted FAT32 (the standard for most thumb drives), not NTFS.
• Step one is to flash to BIOS F32, so copy the F32 BIOS file to the thumb drive. Only the file, not the entire folder if it comes zipped up.
• Perform the Flash as directed in the instructions.
• When the flash is done, don't forget to do the last step: "Load Optimized Defaults" .
• Then Install the EC FW update utility. Always best to restart the PC after the installation.
• Then delete the F32 BIOS from the flash drive and copy over the F50 Bios to it.
• Then install the F50 BIOS.

And then you are ready to upgrade the processor.

Note: always a good idea, after installing the processor and entering BIOS to check it out, to Load Optimized Defaults again, then Save & Exit.
Make any BIOS customizations after you have tested the system and Windows and all is good.

 

MSFS 2020 Throttle

I have the throttle quadrant and it all works fine except the throttle range is from 50% to full throttle only. It will not reduce past halfway.

The game controller calibration works correctly and it works correctly with FSX and X-PLANE.

Any suggestions?

 

Windows 10 thermal throttling

After updating to windows 10 my laptop (Asus n550jv, i7 4700hq) behave very strangly. At the beginning everything works well and under load all 4 cores of processor can work on full load , temprature about 90 C. But after some time, maybe 1-2 hours strange
thing happenes. Processos 100% throttles even when temprature is 66 C. Anyway to fix this ?
