Note: Check the Supermicro website for recommended memory modules.
Important: Exercise extreme care when installing or removing DIMM modules to prevent
any possible damage.
Attention: This system requires the installation of heat spreaders to the memory RAM.
Memory Support
The A2SDi-4C-HLN4F motherboard supports up to 256GB of ECC/non-ECC RDIMM or
512GB of ECC LRDIMM DDR4 memory with speeds of up to 2400MHz in four memory slots.
Populating these DIMM slots with memory modules of the same type and size will result in
interleaved memory, which will improve memory performance.
Note: Check the Supermicro website for recommended memory modules.
