The multiplier is stuck at x21 on my i7 920 even when 0% or 1% of CPU activity is recorded by CPU-Z and PC wizard 2010. Turbo Boost Technology is enabled.

I wonder if this problem has something to do with Hyper Threading, which I have disabled on the Bios.

What about Speed Step?

A20M and C-State Tech are disabled. Speed Step, and all the rest in CPU Setting are enabled. CPU Ratio Setting is in AUTO.

[EDIT] SOLVED

I have enabled C-State Tech, then run routine OS checkings. The multiplier is varying accordingly now.

Thanks.
