Compatible Memory for SuperMicro X12STL-IF

This 16GB DDR4 3200 ECC UDIMM module is built for the SuperMicro X12STL-IF motherboard. It delivers 16GB of error-correcting memory at 3200MHz with CL22 latency and 1.2V operation. The single-rank 2Rx8 design uses major OEM chips from Samsung, Micron or Hynix for server-grade reliability.

Suited for ECC Workstations Not for Non-ECC Systems

This module suits administrators upgrading SuperMicro workstations or servers that require unbuffered ECC memory. It fits 288-pin DDR4 slots and runs at standard 1.20V without a heat spreader. Buyers whose boards lack ECC support or need registered DIMMs should look at something else.

Deciding Spec ECC Unbuffered UDIMM

The single specification that decides compatibility is the ECC unbuffered UDIMM format. Only motherboards that accept 288-pin DDR4 ECC unbuffered modules can use this part. Verify your system documentation for ECC UDIMM support before purchase.

Questions about this item

What real-world speed will the DDR4 3200 module run at in the SuperMicro X12STL-IF?

The module is rated for DDR4 3200 (PC4-25600). Actual operating speed depends on the motherboard's memory controller and BIOS settings; it will run at the highest speed the platform supports up to 3200 MT/s.

How does the ECC unbuffered design affect compatibility with the X12STL-IF?

This is a 288-pin DDR4 ECC UDIMM (unbuffered). The X12STL-IF must support unbuffered ECC UDIMMs; registered or load-reduced modules are not compatible with this UDIMM slot type.

Will the 2Rx8 16 GB stick fit the X12STL-IF DIMM slots without a heat spreader?

Yes. It is a standard-height 288-pin UDIMM with no heat spreader, so it fits the X12STL-IF DIMM slots. The board's slot spacing and latch mechanism accept this form factor.
