Exact-fit DDR4-2933 kit for Supermicro boards

This NEMIX RAM kit provides 32 GB across four 8 GB UDIMMs rated at DDR4-2933 (PC4-23400). Each module is non-ECC, unbuffered, 1Rx8 and runs at 1.2 V with CL21 timings. The 288-pin form factor matches the slot layout required by the Supermicro X12SAE and X12SCA-F motherboards.

Verify slot count and population rules first

Check that your board has four DDR4 UDIMM slots and confirm the approved population order in the motherboard manual. Ensure the system BIOS is current and that the platform supports 1Rx8 non-ECC modules at the rated speed and voltage before installation.

Ideal for owners of the named Supermicro boards

This kit suits anyone upgrading a Supermicro X12SAE or X12SCA-F system to the full 32 GB capacity with matched modules. Builders who need ECC, registered DIMMs, a different speed grade or a smaller capacity kit should look at other memory options.

Questions about this item

What comes inside the MD23400-818K4 kit and is anything else required for installation?

The kit contains four 8 GB DDR4-2933 UDIMM modules for a total of 32 GB. No extra parts are needed; the DIMMs plug directly into the motherboard's 288-pin slots.

Why is this specific 32 GB (4×8 GB) CL21 kit the right choice for the Supermicro X12SAE or X12SCA-F?

It matches the board's required DDR4-2933 speed, 1.2 V voltage, 1Rx8 rank structure and unbuffered non-ECC design, ensuring full-speed recognition without compatibility issues.

What does the DDR4-2933 (PC4-23400) rating mean once the modules are installed in the system?

The memory will run at 2933 MT/s with a CAS latency of 21 cycles at 1.2 V, delivering the rated bandwidth and timing the motherboard's memory controller expects.
