Just finished building my new computer. Two sticks of 8GB corsair 3200 RAM, originally placed in the recommended positions according to the manual - A1 and C1 slots.

Userbenchmark and other tests like memtest86 showed a way below par performance. Just barely over 24GB/s (multi-core transfer rate from userbenchmark). Wasn't expecting any difference but I tried different combinations anyway out of desperation, and much to my surprise I discovered when placed in A1 and B1 instead, the speed goes back to a much more respectable 39GB/s multi-core.

Nothing else has changed. And yes I am using the XMP profile (or D.O.C.P. as the BIOS says) in both cases. So just posting this as a PSA I guess (or please let me know if my RAM placement will have adverse effects).

Cheers
