I have built a new system using the Asus Sabertooth X79\nmotherboard and got a 16Gig of Corsair Dominator GT DDR3 2133 ram to\nuse in the sytem. When got the system ready to power up and explored\nmy Bios I found in the Tool menu that my D1 slot was Abnormal instead\nof OK like the other 3 sticks. When I installed my Windows 7 64-Bit,\nI found in System Properties that I only had 12 Gig of total Physical\nmemory installed instead of the 15 Gig of my set. As a test I swapped\nsticks D1 and C1 and posted it again into the Bios and the same D1\nslot was still Abnormal so the ram was good and the D1 slot was bad on\nthe motherboad. Is it possible to populate the ram insead into the\nA2, B2, C2, and D2 to avoid the bad D1 slot, the ram would be\nrecognised by the Bios and all show up. The motherboard manual shows\nthose slots are used for going to all 8 slots populated instead of\njust using 4 sticks. Would I damage the board further by mounting the\nram in number 2 slots? I hate to have to RMA the motherboad over one\nbad slot; I have Corsair HD80 closed watercooling set up and it would\nbe a major hassle to rip everythiing including my processor out and\nkill my sysem until get a replacement motherboard.
