^ Where'd you look where it said how much cache you had? Do you have the latest BIOS?

Anyways, I tried what you suggested clark and downclocked my RAM to 1333mhz and 6-6-6-12 timings and so far so good.. I've tried this before but with 7-6-6-24 timings. My system was pretty stable but then one time my computer reboot. I didn't try much testing at 1333mhz though. I think that's horrible to have to downclock memory because this board can't handle 1600mhz ram when you have a powerful video card... I see this motherboard differently now. I'm probably staying away from Intel from now on. Shouldn't have to downclock on something when you upgrade a video card. Hopefully it's something that can be fixed in a BIOS update but I doubt it. Intel probably won't release another BIOS for this mobo.
