Hyperthreading?

[Eklips]

DOes hyper threading work ..if i upgrade my win2000 with service packs...and if i enable hyperthreading i can use windows media player and play a game at the same time? When using HT in w2000...on startup does it recognize duel processor?

Hyperthreading does work. However it won't work with Windows 2000. You need Windows XP or Linux.

It work on Win 2K but a bit slower that win XP.

I dont like french test

It work well on Win 2K on HPC and stuff but on game and such ther a small effect - or +.

Do you know of any sites that have done a side-by-side comparison? I was under the assumption that Win2k did not support HT at all. My apologies to eklips for the misinformation.

Hmm, at its core Win2000 should support HT. How I understand it is that Win2000 supports dual CPU's, hence HT. Enabling HT in BIOS should sorta "trick" Win2000 into thinking you really have 2 CPU's. If you check CPU Usage under Win2000 with 1 CPU running with HT it will show 2 CPU's running, hence the Bios trick.

Now XP probably is better optimized for SMP or Dual CPU's in general, therefore a HT CPU probably does run better in XP.

Windows 2000 and Windows xp both support SMP, and hyperthreading. However Win 2000 has licensing retrictions problems. If you enable hyperthreading on a dual xeon, your computer will not work under win 2000. win 2000 will recognize the cpu as 4, which is violating licensing restrictions of only 2 cpu per OS.
