To Hyper-thread or not to hyper thread? that is the question!

No. Turning it on allows for the CPU to handle multiple threads. The reason you would want to turn it off is it can actually slow some apps and is not supported by operating systems before XP.

Edit: I listed the 3.06 w/ 533 FSB because it supports HT.

Some programs may have problems with HT. So you can turn it off in the bios if you need to.

This can be true but most programs I have tested andi have tested a lot of them show no effects to modest effects to tremndous performance increase....

Unless you are running a non supportive OS or that one important app that as some issues with it, it would be crazy not to run with it turned on....

Often times an app may not be optimised for it but results could still be improved performance...How you ask?? because the OS can take advantage of the HT and run background apps or some other program you may be running in the background (watching a DVD, burning a DVD, or downloading on the interent) with little or no hit in performance of the main app you are running....

Check out my HT testing in the cpu forum...I have a review coming on a Barton 3200+ machine doing those same things and it really shows the sometimes forgotten or overlooked advantage Intel cpus have over their counterparts...
