This is a Dell Dimension 8250 with a P4-3.06 HT processor, a gig of ram
, and a GeForce FX5900XT(128mb) video card. I recently came across an article that mentioned hyperthreading being enabled or disabled, and that if you are running programs that don't take advantage of hyperthreading, having it enabled in the BIOS
actually degrades performance.
I looked into my setup-as Dell calls it, and see that Hyperthreading is enabled. While there, I noticed this "Video DAC snoop" setting. Mine is disabled(I bought this computer second-hand on ebay). It came with an ATI Radeon 9700pro card. I got rid of it(problems in Far Cry and Doom3), and installed a GeForce FX5900XT.
Can anyone tell me if this Video DAC Snoop should be enabled or disabled?
Also, do you agree that enabling HT in the BIOS
is the wrong thing to do? I have yet to come across a program that works with, or uses HT.
