Just ordered a 2.4C and was wondering if i have to install Windows again to get HT support

Do this: IN ORDER

1) Goto device manager and upgrade the driver of your "computer> ACPI uniprocessor PC"

Change it to "ACPI multiprocessor PC"

Power down. Install the chip. Power on and go into bios immediately. Make sure HT is enabled. If so, boot windows normally. Windows will find all your hardware again and it wil be fine.

u can turn ht on and off with only a slight difference in performance.
u dont have to do anything but change the bios
i found that a fresh install after ht changed the performance very little

ps i am assuming u are using xp pro

[sapiens74]

Yeah its XP Pro.


I saw the option to upgrade the multiprocessor, so Ill give that a a shot when the Chip comes in

when i got this a year ago last feb it came with ht off (before xp sp1)
i turned it on and ran some sandra tests
then i reinstalled xp and the numbers changed very little

i went to intel to read about ht and the white papers said not much is needed to run ht. the system will use the logical proc to precache for the physical one

try it both ways and me know if there is a dif between the xeons and the regular p4's. i would like to know
