hyper threading won't disable

Andy_pandy · 15 May 2013 at 23:10

For some reason, my ASUS P8Z77-V motherboard will not disable hyper-threading. I went to into BIOS and went into advanced and disabled hyper-threading. I exited the BIOS and clicked " Save & Reset". When my PC booted into Windows 7 it still showing 8 cores. I checked the BIOS and it says Hyper-threading disabled.

I have updated my BIOS and updated my Windows

This is my current PC spec:

Intel i7 3770K
ASUS P8z77-v
AMD 9750
8GB Corsair XMS 3
650 XFX PSU

I have the same motherboard and it does have problems with settings getting stuck, the latest bios (1908 I think) seems to be a little bit better in this respect.

Changing BCLK or running the OC Tuner in bios usually forces a 'hard' reboot (pc powers down completely then starts rather than just rebooting). Failing that it's clear cmos with jumper I'm afraid

This is strange could the bios be corrupt?? On all my ASUS boards it disables fine as I use it disabled for the majority of benchmarks.

I've had issues with iGPU, CPU multiplier, voltages and hyperthreading on/off values sticking with this particular motherboard

Full power off start?

Would have to read the settings directly off the chip then.
