Question about overclocking a Quad core cpu

Could you disable two of the quad cores in the bios and overclock it with the same heat output and power usage as a duo core cpu ???? :confused:

Some boards allow you to do this, I think the EVGA 680i has the option to disable all but Core 0 in the BIOS and I think the Bad Axe has something similar.

why would you do this? :confused:

I don't know whether this why the OP asked.

But perhaps he would be able to clock the Q6600 like an E6600, for use in games (with 2 cores disabled ofc)

Then use the full 4 cores for programs that utilize all cores, at a lower clock.

This might not be possible, I don't know. So don't flame if it isn't please :p

Yes to what you said....

Plus i be able to save on the electric bill by only running one or two cores went 4 not needed...

Benchmarking.

Only Jokester would have thought of this one ;)
 
All multi-core CPU overclocks are held back by the weakest core so being able to disable each core individually is very useful in finding out how fast it could go if it didn't have one slow core.

Then you actually want to turn on Speedstep as it does exactly that.

But don't speedstep just turn the core speeds down ???

I didn't think speedstep disables any of the cpu cores....

Yeah Intel Speedtep lowers the multiplier which in effect lowers the clock speed of the CPU... but once its under load the multiplier goes higher again :)

I think disabling some the cores would use less electric...(maybe :confused: )

I don't see why it wouldn't but wouldn't it be better if you used SpeedStep? as that would allow you to use all four cores whenever you needed? And saves you visiting the BIOS every time you wanted to enable them.
