2-3 Memory Support
The A1SA2-2750/2550F motherboard supports up to 64GB of DDR3 ECC VLP
UDIMM 1600MHz in eight memory slots. Populating these DIMM modules with a
pair of memory modules of the same type and same size will result in interleaved
memory, which will improve memory performance.
Note
: Check the Supermicro website for recommended memory modules.
CAUTION
Exercise extreme care when installing or removing DIMM
modules to prevent any possible damage.
Memory Population Guidelines
Please follow the table below when populating the motherboard.
