Can anyone tell me how to cancel hyperthreading on an i7 DFI Lan Party motherboard.
I can't find any mention of HT in bios
Thanks,
Jack

It should be in the BIOS. If it isn't it doesnt support it (The CPU thats on it). Not all high end CPU's do

I'm pretty sure it does. Task manager shows twelve processors.

Which I7 is it. Look on Google / the intel site for the CPU. It it says it doesnt support HT then the option wont be in the BIOS

All i7 CPUs have HTT. It should be in the BIOS, very unlikely DFI would make a BIOS that doesn't have that option.

Look in the manual for the option

It might be somewhere stupid - I found the option to turn on hardware enabled virtualisation extensions on my PC under "System Security" settings in the BIOS.

Why do you want to cancel it ?

Some believe it lowers power consumption and therefore heat, as HTT only offers some improvement in a small amount of apps its seen as worthless unless you specifically use one of those apps of course.

Personally I couldnt see a tangible thermal diff between on and off when testing so I just leave them on.

Lol it DOES, my i7's temps drop by 10 degrees when HTT is off.

I have wondered if its quality of cooling or overclocking related, do you overclock and what cooler?

I'm not sure exactly why it gets hotter with HT on. With HT on at 4GHz I need 1.33v. Cooled by a Prolimatech Megahalems with 2x 2000rpm fans, but now I'm getting slightly better temps with a Noctua NH-D14.

Weird I had no tangible diff running a few instances of Prime HTT on or off, noticed a few threads arguing over it. Guess if it has a effect for you turn it off, my temps are good so it wasn't a issue.
