If Windows 32-bit supports 4GB of ram on a motherboard but Windows 64-bit does not - on the same motherboard - logic sez that the problem is NOT with the motherboard but with Windows 64-bit. Now do us a favor, Colin, don't come back and tell us that your Vista Ultimate 64 sees more than 4 GB of RAM cause one has nothing to do with the other

Not if, as this particular mobo does, the mobo has a timing flaw affecting only 64-bit systems. I bought it right after it first came out. The manufacturer corrected the problem in later revisions of the board but the first generation boards will bluescreen if booted with a 64-bit OS and 4GB or more is installed. I will eventually replace it, but I am giving the boards supporting the new quad-cores some more time to mature before doing anything about this one.
