Ahh, thanks for the heads up. I suppose I'll have to go DDR3 if I want to get super-duper high FSBs?

I've taken it down to 400x8/1066 mem for now, while I'm out of town for a few days. Also dropped the voltage a bit, so it seems alright. I'll continue tweaking on Tuesday, after I pop in the new radiator.

I was going to get the much cheaper DS3R, but I'm glad I got the DFI. Still can't get over the name gigabut.
