Sa2 memory

Context? Where did you see this?

I don't recognize this either.

my motherboard(gigabyte ex58-ud3r) manual says that for dimm slots 2 and 3(there are 4 dimms), sa2 memory must be used.

I own the same mb, and am wondering exactly the same question.

I currently have 3 Corsair 2GB DDR3 modules, and was thinking about filling up the 4 slots with a fourth when I came across with that line in the manual.
