txmx,
One other thing Asus boards are notorious for is under reporting CPU temp. At the moment, I'm at 100% cpu utilization (folding) and Asus probe reports CPU temp of a nice cool 34 degrees C (93 F). However, my Corsair Hydrocool thermistor reports the top of the waterblock is 33 degrees C (91 F) and my Thermaltake thermistor reports the bottom of the waterblock is 40 degrees C (104 F). There is no way the CPU is running cooler then the waterblock. Add at least 10 degrees C to whatever the Asus bios or probe reports.
Gunslinger,
In my previous post I was refering to the ram you already own. Any system capable of dual chanel DDR will be faster with two sticks of ram @ 1:1.
