Hello.

I've just installed BIOS 1.12.1 and now I can't undervolt my CPU anymore. Before the BIOS update I was able to underclock the CPU to -0.150 mV (Core/Cache Voltage Offset via Intel XTU), which is the only way I found to keep the CPU from thermal throttling. Now, the Intel XTU core voltage offset slider is disabled, furthermore I'm not able to rollback to a previous BIOS version (1.11.1 or 1.9.1). I got this error message while running the BIOS update: "ME Firmware EndUpdate Failed Error: 0x000001F3".

Windows device manager shows no errors on the Intel Management Engine Interface.

ThrottleStop also has no effect anymore.

Now, my CPU is thermal throttling like crazy! This is unacceptable, please help.
