Hi all, In testing my old X99 Deluxe (not version II) I ordered a Deluxe II as a potential solution. However, it only seems to see half the RAM that I've plugged in and I'm not sure what I'm doing wrong to make it see the rest. RAM is known to be working (tested in other PCs and it sees it all just fine) and moving them between slots makes them show up again (E.G., from B1 to A1). DIMMs A1, A2, D1, D2 all show RAM but if I place any RAM in B1, B2, C1, C2 it doesn't show as per attached screen shots. SPD information shows partial information, just not the size or the speed. Does anyone have any ideas?
