What is the FSB reporting as? 400 or 800?
It's possible for windows to guess wrong on installing HT support, but the BIOS should have it as an option. Using something like Everest Home Ed, what is the motherboard identified as?
Is this the CPU that you had in your 5660 or did you have sager put I new one in?
If its is the one you had in your 5660 then more then likely its the 2.8Ghz p4 w/ 533 FSB and Intel started HT on the 3.06 GHz and the only 2.8 that has HT is the Prescott P4. but if you really want HT you can get Northwood or prescott CPUs real cheep off newegg.com just make sure you get the 478 pin P4 and NOT the LGA 775.
Just keeping mind if you buy a Prescott it will run a little hotter. Because the Prescott 478 pin CPUs did have a little of a heating issue so get some Artic silver 5 or 3 (preferably AS5)
