Memory Support

The X12STW-TF supports up to 128GB of DDR4 ECC UDIMM memory with speeds of up
to 3200MHz in four memory slots. Refer to the tables below for the recommended DIMM
population order and additional memory information. For validated memory, use our
Resources page. Check the Supermicro

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.
