Turbo malfuncion (GA-B150M-DS3H + BIOS F20)

[John Gabriel]

Hello, I have just updated BIOS on my motherboard (GA-B150M-DS3H) from version F4 to F20. Now even Intel Speed Shift technology works on my W10 14393.447 and Intel Core i5-6500, but the operating frequency range of CPU is limited just on 3200 – 3300 MHz’s.

I have discrete Radeon R7 360 so iGPU is turned off and previously it worked in turbo mode from 3300 – 3600 MHz, and even the benchmark (as the one integrated into the CPU-Z) gives significantly lower results!

I’m asking for any help, is there any solution? From F20, there is unfortunately no way back to older BIOS versions.... :-(

Thanks

Another option for BIOS downgrade here:

Renaming the desired bios file to bios.bin effectively uses boot block recovery which is a less discussed part of the chips default recovery option.
