Memory Support
The A1SAM/A1SRM Series motherboard supports up to 64GB of DDR3 ECC
or Non-ECC Unbuffered (UDIMM) 1600/1333 MHz in x8 data width only, in 4
Default
memory slots. Populating these DIMM modules with a pair of memory modules
Off (Normal)
of the same type and same size will result in better memory performance.
Pins 2-3 (Disabled)
Note: For memory optimization, use only DIMM modules that have been validated by Supermicro.
Pins 1-2 (Enabled)
For the latest memory updates, please refer to our website a at http://www.supermicro.com/

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.
C Header
•
The motherboard will support one DIMM module or three DIMM modules in-
2
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.
