No Hyper Threading with Prescott 3.0

Hi,

I have a few problems with a system im putting together.

Asus P4C800 Deluxe motherboard.
Prescott 3.0
Gforce 4 TI 4200 8xAGP
Windows XP Pro.

If i enable Hyper Threading in the BIOS, the system hangs in the windows startup, or just after windows have loaded. It then reboots and throttle back to 1.5 Ghz, under which it runs fine with HT. Im however not entirely pleased by this ;-)
When i pay good money for 3.0 Ghz with Hyper Threading, thats what i want.
I have installed all the latest drivers, but still no luck.
I have also disconnected CD-RW, HD #2 and the floppy, to see if i had insufficient power (run antec 380 W PSU), this had no effect, so i take it my supply is amble.
Anyone out there with a good idea ?

P.S. It better be more than "a good idea" as i have tried most already :-)

How do you return things BACK ??

I was only joking ! I dont need to return the processor, there is nothing wrong with it. Its something in my setup which stops the HT.
I need to find out what !

Just seemed the right thing to reply to a guy, who came up with #2 to solve my problem. I will have the same problem with HT in Northwood.

I think thats why he is here ideas.

"When you enable hyperthreading with DC memory in XP-Pro you should see 2 CPU's running at 1.5ghz. 2 X 1.5 = 3ghz.
Probably nothing wrong at all."

Dont know where you read that, but if you are running your system like that, you are down ½ speed.
HT should show up are TWO processors of the actual speed. In my case 3.0 Ghz.
Now and again im able to run it like that, but only for awhile, then it shuts down, go 50% and reboots.

Hi,

Yes i have the latest BIOS. I will try to get a bigger PSU and have a go with it. But 380 W really should be ok.
