Did that work for you, hardboiled?
I'm building the same M3A78-EM / AMDx2 4850e based system, and I'm looking at all the issues surrounding RAM. (for extra info, I'll also be using a GeForce 8600GT)
Are there any solid RAM recommendations? All I find are people with a mound of trouble shooting to do.
Any best practices out there regarding RAM for this Mother Board?
