NEMIX RAM 32GB (2x16GB) DDR4 2933MHz ECC UDIMM CL21 1.2V 288-pin 1Rx8 memory upgrade

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.
