Q9550 only runs one core- help!

[kahuna321]

Checked all drivers, bios, etc- even intel validator, only one core running.

Setup:
Gigabyte GA E45P UD3R
Mushkin DDR2-1066 8 gigs
Vista 64
Asus 4870x2 Trifan
Creative Titanium Pro
Killer NIC
True lapped with Sythe S flex F
NZXT Tempestw/ 250CFM intake & 230CFM exhaust
WD Caviar Black 640 2 platter 32mb x2 in Raid 0)

This setup runs rock solid stable at 1800 FSB with E8500@4.275G- orthos and intel burn test for 10 hours ea+, and vantage scores of 12,890 cpu/gpu

Am I missing a bios setting, or do I need to flash the bios to later revision- or do I have a bad processor?

Thanks a bunch,

Running slow in Seattle

What does it run when not OC'd

 

[blackpanther26]

did you enable multi core support in BIOS?

 

[kahuna321]

runs one core both at stock speeds and clocked

checked bios at least a dozen times and can't find a setting for cores

thanks alot for the help

i have loaded several different applications and watched performance monitor

yes, it is set for one graph per core

thanks

Have you tried CPU-Z... If that says 1 core then I am thinking you have a duff chip somehow
