I have this motherboard:
which I have been running with (2 x 4GB) of RAM. It’s got 4 slots so I decided to add another 8 GB of exact same type (except for version):
So any combination of 2 of these 4 modules in any paired set of slots (grey or black color) will let me POST as usual, but IF I put all four in, no matter the order or pairing, it won’t. Sigh…
Any reason this shouldn’t be working? Any thoughts re: troubleshooting?
