Is Hyper Threading being phased out?

It was enabled by default on the Intel D865 board I just used for a build.
 
Wouldn't XP Pro have to be patched already to enable four logical CPU's now, for a dual CPU HT enabled system?

We just had a new BIOS rollout and HT is disabled across the board by default on our Xeon workstations.

All of the Dells that have been ordered for clients also have it disabled.

I turn it ON.

What is all the fuss about? Turn it off or leave it on?

Any input would be appreciated.

Cheers!

They are probably turned off by default to be compatble to older OS like NT4 & win2k...

If you use Win2003 then yes by all means turn it on.

That is what I was htinking too... But I coulda sworn I used my older p4 rig with win2k at one point and HAD hyperthreadin enabled...

Q: Is it posisble to run win 2k with hyperhtreading?

NT based OS' previous to 5.1 (XP) will see each virtual CPU as a physical CPU. It's a double edged sword. Some apps work well, while others stumble and performance drops. It's also important to remember that (in the case of a dual Xeon) 2000 will not see all four virtual CPU's unless you're running Advanced Server or Datacenter Server. NT will require Enterprise Server. Of course I would hope you consider upgrading soon if you're still in the 4,x realm. 🙂

Cheers!
