I'm trying to help a contact with a memory upgrade for an MSI 975X Platinum motherboard and he's bough a 2 x 2GB PC6400 upgrade kit but can't boot into Vista 32bit with both DIMMS installed. He's tested both separately and they work fine, just won't boot into Vista. He knows he's only going to be able to use 3.blah GB of it in 32 bit Vista but what could be preventing the boot with both DIMMs? This is with a Q6600 installed.
Cheers
