Q6600 overclock - applied to only 2 cores?

[Barno]

I've just overclocked my Q6600 G0 to 3.4ghz. In cpu-z the processor speed is shown as 3.4ghz but in open hardware monitor only cores 1 and 2 display the overclocked speed while 3 and 4 are shown to be running at stock speeds. Has anyone else encountered this before? Is it a bug or are 2 of the cores not taking the overclock?

My motherboard is an Asus P5KR. Speedstep and C1E are turned off.

Cheers.

Well cpu-z says that all cores are functioning and that the speed is 3.4, as does windows 7. Although neither of those tools break the speed down into individual cores.

Fixed it - fiddled about with the bios and disabled a few settings. All 4 cores @ 3.4ghz now
