NEMIX RAM 32GB (4x8GB) DDR4 2933MHz CL21 ECC UDIMM memory upgrade

Exact-match DDR4 ECC kit for Supermicro X12 boards

This 32 GB kit contains four 8 GB unbuffered ECC UDIMMs rated at DDR4-2933 (PC4-23400) with CL21 timings and 1.20 V operation. The modules use a 1Rx8 organisation and 288-pin layout that matches the memory-controller expectations of the Supermicro X12SAE and X12SCA-F motherboards. Builders who need registered DIMMs or SO-DIMMs should look elsewhere because this kit is strictly unbuffered UDIMM.

ECC protection and verified fitment

On-die error-correcting code detects and corrects single-bit errors in real time, preventing silent data corruption and unexpected reboots during critical workloads. The kit is validated for the exact DIMM population rules of the target Supermicro boards, so the system recognises the full 32 GB at the rated 2933 MT/s without manual tuning. No heat spreaders are included, leaving clearance for dense server chassis.

1Rx8 rank organisation decides compatibility

The single-rank 1Rx8 density per module is the specification that determines whether the motherboard can populate all four slots at the rated speed. Systems requiring dual-rank modules or a different rank-per-channel limit will not support this configuration at full capacity. Consult the board manual for approved population order before purchasing.
