just picked this board up, popped it in and everything works with 1x 4gb gskill ripjaws ddr3 1333, but when i pop in a second stick I get a debug error of 55, which is obviously memory not installed. System boots fine with a single stick in A1/A2 but any additional stick i get error 55. I've reseated CPU, checked for bent pins and don't see any, each individual stick works in both A slots, anyone have any ideas? My memory isn't on the "supported" list and wondering if that could be an issue.
Incompatible memory configuration. You need a stick in A1 and B1, rather than A1 and A2. For best performance you need identical sticks in A1/B1 and A2/B2. Basically don't use an odd number of memory chips and install the pairs into the correct sockets.
Starting at the CPU socket, the slots from left to right are A1, A2, B1, B2. So, using 2 identical memory chips, you would populate like so...
e.g. 4GB (A1), empty (A2), 4GB (B1), empty (B2)
