Disable P4 Hyprerthreading?
Disable P4 Hyprerthreading?
(OP)
I keep hearing rumors about needing to disable the Hyperthreadng functionality in the newer P4s when using SW. I searched here and the SW Knowledge Base, but couldn't find anything concrete aobut having to disable this. We are looking to build a few new systems and if anyone could shed some reliable light on this subject, that would be great.

OK, sorry for the ribbing. My AMD systems are very stable, but sometimes you have to do what the boss asks for.
I'm afraid my post isn't otherwise useful. You might check Tek-Tips.com--I've gotten good help there before.
By the way, I love your sig file. Thanks for the clarification in another thread when I referred to it. (Kinda makes my point of Intel's foul-up regarding 64-bit chip architecture development.)

A) Processor must be P4 3.06 GHz or higher, or Intel Xeon (Xeon processors do not have to be >3GHz)
B) Need special motherboard
C) HT must be enabled in BIOS
D) OS to be Windows XP SP1 or higher
So maybe that is why you are not seeing any "problems".
