Memory Support

The A1SAM/A1SRM Series motherboard supports up to 64 GB of DDR3 ECC or
Non-ECC Unbuffered (UDIMM) 1600/1333 MHz in 4 memory slots. Populating
these DIMM modules with a pair of memory modules of the same type and same
size will result in better memory performance.
Note 1: Check the Supermicro website for recommended memory mod-
ules.
Note 2: Be sure to use memory modules of the same type, same speed,
and same frequency on the same motherboard. Mixing of memory modules
of different types and speeds is not allowed.
Exercise extreme care when installing or removing DIMM
