The A1SAM/A1SRM Series motherboard supp orts up to 64GB of D DR3 ECC

or Non-ECC Unbuf fered (UDIMM) 160 0/1333 MHz in x8 data width o nly, in 4

memory slots. Pop ulating these DIMM modules with a pai r of memory modules

of the same type and sa me size will result in better memory per formance.

Note: For memory optimization, use only DIMM modules that have been validated by Supermicro.

Memory Population Guidelines

When installing memory modules, the DIMM slots should be populated in the following

order: DIMMA1, DIMMB1, DIMMA2 and DIMMB2.

• Always use DDR3 DIMM modules of the same size, type and speed.

• The motherboard will support one DIMM module or three DIMM modules in-

stalled. However for best memory performance, install DIMM modules in pairs.

• 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.
