I have a pair of these on my LANPARTY LT X48-T2R and I have a few problems.

System:
LANPARTY LT X48-T2R
F2-8500CL5D-4GBPK
Corsair 750W PSU
Xeon E3110

I've been trying to OC this chip to 4ghz stable and can't seem to get it to pass Orthos blend and most of the time it locks up during initial post or halfway through the loading of Vista.

Just for the hell of it i put my brothers 2x1 sticks of Corsair in the board and it's completely stable at all the same settings and passes with flying colors.

I have tried setting my RAM to 5-5-5-15 52, upped NB volts from 1.91 (default i think) to 1.40v, and have taken the RAM to 2.2v for one run just to see if that would work.

I have setup 9x multi, 445fsb, 5-5-5-15 52, RAM is showing at 1069 speed in the bios and failing miserably. It's also very odd that i can't boot at different strap speeds at all other than the AUTO that puts it at 1069. I'm not sure why that's happening.

Any help would be appreciated and if there is any info that i left out or should try please let me know.
