A pretty decent MB for 2011 V1/2 single core WS built. Has 8 dimm slots. Can use udimm, rdimm, and LRdimm. One of the few single cpu 2011 v1/v2 board that allows for lrdimm.
can also run i7 sandy and ivy -E cpu, but only with udimm.
The one major disadvantage of any supermicro X9 board is the very spotty S3 sleep support. On this particular MB, S3 sleep is highly variable. YMMV. For example, I have two 2660v2, one will have s3 sleep fine with this board, the other 2660v2 won't. both these cpu run perfect and sleep perfect with other 2011 MB.
