Memory Support
The X12STL-F supports up to 128GB of ECC UDIMM memory with speeds of up to 3200MHz
in four memory slots. Speed support is up to 2666MHz when a Pentium processor is installed.
Speed support is up to 2933 MT/s for 2R2R configurations. Refer to the table below for the
recommended DIMM population order.
Note:
Memory speed support depends on the processors used in the system.
For validated memory, use our

Check the Supermicro website for
possible updates to memory support.
Memory Installation Sequence
Insert the DIMM modules in the following order: DIMMB2, then DIMMA2, DIMMB1, DIMMA1.
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.
