running Windows 7 64-bit Home Premium.
My 920 uses hyperthreading, and since I don't have any applications that use more than four cores, it was recommended to me that I disable hyperthreading for a slight performance boost in CPU-intensive games such as ArmA 2 and Bad Company 2.
My question is: can I turn hyperthreading off without having any sort of negative repercussions? I obviously installed Windows with it on, is there any chance of creating problems by turning it off?
HT mght decrease performance in some games but the decrease is minimal. I play my games with it on with no issues. While turning HT off may increase performance, at this point it wont hurt it. So no turning HT off will not hurt anything, and it may or may not increase performance.
Yeah, I had researched whether it would actually help my performance or not, and for most games it's quite minimal, but for games like ArmA 2 I've heard that the increase might be a bit more significant.
What I really need to know is whether disabling hyperthreading will cause any problems, whether with the OS, or anything.
Thank you all for your answers, I really appreciate your help.
ElMo, that's quite an amazing rig you've got there, although I can't help but think you should've gone with quad-fire, especially with Catalyst 10.7+ offering extremely improved quad-fire support.
Gamerk, that's what I've been doing for about a year now, but recently I've noticed some ArmA 2 players strongly recommending others to disable hyperthreading, and that's a game I've had some performance issues with.
Hey, as long as there's no harm involved, I'm game for trying, so I'm off to the BIOS to disable it right now! Thanks again.
