Memory Support
The X12SPA-TF supports up to 1TB of ECC RDIMM, 4TB of 3DS RDIMM, 2TB of LRDIMM,
or 4TB of 3DS LRDIMM with speeds of up to 3200MHz (2DPC) in 16 DDR4 (288-pin) SMD
DIMM slots.
Note: Memory speed support depends on the processors used in the system.
For validated memory, use our
possible updates to memory support.
Memory Installation Sequence
Memory for this motherboard is populated using the "Fill First" method. The DIMM slots
with blue release tabs are considered the first DIMM of their channel, and those with white
release tabs are the second of the channel. When installing memory modules, be sure to
populate the memory slots with the blue release tabs first and then populate those with the
white release tabs.
General Memory Population Requirements
1. Be sure to use the memory modules of the same type and speed on the motherboard.
Mixing of memory modules of different types and speeds is not allowed.
2. Using unbalanced memory topology such as populating two DIMMs in one channel while
populating one DIMM in another channel will result in the reduced memory performance.
3. Populating memory slots with a pair of DIMM modules of the same type and size will
result in interleaved memory, which will improve memory performance.
