My memory would not run at 1066. Prime would error out on blend. I'd like to get it to 1000, but the 266 strap won't boot. There's some more tweaking to do on the memory side.

My north bridge is HOT. I have the included ASUS fan on the regulators and 2 40mm fans directly on the north bridge. After an hour of OCCT it's 66C! It idles in the low 50s. Lower voltages lead to instability, so that's it for now. Once I get the ambition to tear everything apart I'll put a water block, or aftermarket cooler on it. My hottest core was 57C after the 8 hour prime95 run.
