I have built a new system using the Asus Sabertooth X79 motherboard and got a 16Gig of Corsair Dominator GT DDR3 2133 ram to use in the sytem. When got the system ready to power up and explored my Bios I found in the Tool menu that my D1 slot was Abnormal instead of OK like the other 3 sticks. When I installed my Windows 7 64-Bit, I found in System Properties that I only had 12 Gig of total Physical memory installed instead of the 15 Gig of my set. As a test I swapped sticks D1 and C1 and posted it again into the Bios and the same D1 slot was still Abnormal so the ram was good and the D1 slot was bad on the motherboad. Is it possible to populate the ram insead into the A2, B2, C2, and D2 to avoid the bad D1 slot, the ram would be recognised by the Bios and all show up. The motherboard manual shows those slots are used for going to all 8 slots populated instead of just using 4 sticks. Would I damage the board further by mounting the ram in number 2 slots? I hate to have to RMA the motherboad over one bad slot; I have Corsair HD80 closed watercooling set up and it would be a major hassle to rip everythiing including my processor out and kill my sysem until get a replacement motherboard.
