Exact-match DDR4 ECC kit for Supermicro boards

This 32 GB kit contains two 16 GB DDR4-2933 UDIMMs built to the PC4-23400 standard with CL21 timing and 1.20 V operation. It is designed for the Supermicro X12SAE and X12SCA-F motherboards, matching the rank, voltage and timing the memory controller expects so the system recognises the full capacity at rated speed. Builders who need a different form factor such as RDIMM or SODIMM cannot use this kit.

Unbuffered UDIMM build with ECC protection

The modules use a standard 288-pin unbuffered layout without a heat spreader, keeping height low for tight server chassis. On-die ECC detects and corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots in always-on workloads. The 1Rx8 organisation follows the board's population rules, so installation follows the manual's slot order without surprises.

1Rx8 rank configuration decides fit

Each DIMM is organised as a single-rank 1Rx8 device, a detail the memory controller checks during training. If your platform requires dual-rank modules or a different rank-per-channel limit, this kit will not post at full capacity or at its rated 2933 MT/s. Always verify the motherboard's qualified-vendor list and population guide before ordering.

Questions about this item

Does the DDR4-2933 (PC4-23400) interface cap the memory speed on a Supermicro X12SAE or X12SCA-F board?

The modules run at DDR4-2933 (PC4-23400) with CL21 timing at 1.20 V. The board’s memory controller will operate them at this rated speed when populated according to the manual.

What physical slot and form factor do these 288-pin UDIMMs require?

They need standard 288-pin DDR4 UDIMM slots. The kit is unbuffered ECC, not RDIMM or SODIMM, and has no heat spreader, so it fits the X12SAE and X12SCA-F DIMM sockets directly.

How do I install the 2×16 GB kit correctly, and which step is often missed?

Power off, open the chassis, align the notch on each 288-pin module with the slot key, press firmly until the retention clips click, then consult the motherboard manual for the approved population order — skipping that order is the common mistake.
