is there a way to disable hyperthreading on the hp dv6 quad core laptop?

‎04-16-2012 06:26 PM

I recently purchased the dv6 quad edition laptop with the intel i7-2670QM processor.  It already has 4 cores, and I have no need of the hyperthreading to divide them into 8, as I'm not even able to use all 8 if I wanted to.  I was hoping to be able to turn it off so as to increase the power of the individual cores.  I could be wrong, but it seems to me that if a core is cut in half and running at 100%, it's performance would be improved by having access to use the whole core for the single thread.   I've been looking around and it seems that a lot of people have similar issue, but I'm just wondering if there is anything that I can do with the BIOS in order to open up the ability to enable/disable hyperthreading.  It doesn't really make sense to me that it is disabled for hp in the first place...

If there is not a setting in the bios to disable processor hyperthreading then you cannot. No the bios cannot be modified to do it, sorry.

 

 

.

A similar question was asked on this forum, very smart people over there, and it can only be done in the bios, but there is a complex solution for disabling some of them for any given program, see answer by member Breakthrough.
