ECC UDIMM kit for Supermicro X12SAE/X12SCA-F

This 16 GB kit uses two 8 GB DDR4-2933 ECC UDIMM modules built to the exact rank, voltage and timing the Supermicro X12SAE and X12SCA-F memory controller expects. The 288-pin unbuffered form factor matches the board slots and the CL21 1.2 V specification ensures the modules are recognised at full capacity and rated speed.

Ideal for ECC server builds.

Builders upgrading a Supermicro X12SAE or X12SCA-F platform gain single-bit error correction that prevents silent data corruption and unplanned reboots. The kit will not function in systems that require registered DIMMs, SODIMMs or non-ECC memory, and it cannot serve platforms limited to lower DDR4 speeds.

1Rx8 unbuffered ECC at CL21 1.2 V

The single-rank-by-eight organisation and unbuffered ECC design are the decisive specifications; if the motherboard manual calls for 1Rx8 UDIMM ECC at CL21 and 1.2 V, this kit meets that requirement exactly.

Questions about this item

How can I verify the kit runs at DDR4-2933 CL21 after installing it in my Supermicro X12SAE?

Enter the BIOS and confirm the memory frequency shows 2933 MT/s with CAS latency 21; the ECC UDIMM modules are spec-matched to the board so they should be recognised at full rated speed without manual tuning.

What does the ME23400-818K2 package contain and is anything else required?

The box includes two 8 GB 288-pin DDR4 ECC UDIMM modules for a total of 16 GB; no heat spreaders or extra cables are included and nothing else is needed for installation.

Should I choose the 1Rx8 16 GB kit or a different capacity for my X12SCA-F build?

This 16 GB (2 x 8 GB) 1Rx8 kit matches the motherboard's validated population rules; select it when your workload fits within 16 GB and you want the exact rank and voltage the board expects.
