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 [email protected] 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,

Re: q9550 only runs one core- help!

i went ahead and installed processor in another system with same model motherboard and the quad runs as it should- great! oc'd to 3.825 (450x8.5), passed one round of inteburn already. runs a little hot idle- 39-41, and really hot loaded- 74 max.
this system has an unlapped true with a 40 cfm fan. not gonna change anything for now, but will put in faster fan as soon as i get it. Since i may have somehow damaged the original mb when changing processors, im not gonna lap the true in 2nd system- at least until i get brave again!

thanks for all the helpful advise! someday i might even learn enough to be of help to others...
