HT on a p4 2.8?

[balto2k3]

I was reading somewhere that some ppl on the new were saying they got a p4 2.8 to run in hyperthreading via a bios upgrade... Has anyone heard anything about this?

Thanks

According to intels web site only the 3.06 supports HT. In order for HT to work u need both the processor and the mobo to support it. I have heard about bugs in some mobos that have HT support enabled as reading p4 2.4ghz as 2 seperate processors running at 2.4ghz each, mebe thats what they were refering to.

That is what I thought 🙁 Well I just ordered my p4 3.06 HT and a msi mobo... Plus a gig of ram.

Don't forget the Operating system.😉

I've only seen this with P4 3.06. Where did ya see this with a P4 2.4? Just curious. Not a bug, it's supposed to look that way.😕

Not possible. HT is hardware disabled on the P4 2.8.

WHAT?! not everyone uses win xp?! 😛

I read this somewhere in the forums. It was late dun really remember exactly what the problem was, but sumtin about wcpuid reporting 2 processors even tho the p4 he had didn't support HT.

I think that your confusing the p4 and the xeon processors. On all of the new xeon's 2.4ghz and up are HT enabled. Don't know if you can use a single xeon in a p4 motherboard.

buick beast- you can't use a single xeon in a p4 mobo, it uses a different socket
on a side note, the aero eng department here at iowa state has a nice new lab of dual ht xeon dell workstations w/ 2 gigs ram each and either128 or 256 meg graphics cards (can't remember which specific card), running redhat
almost makes me not mad we pay higher computer fees each semester than com sci students :|
