NEMIX RAM 8GB DDR4 2933MHz PC4-23400 1Rx8 CL21 288-PIN ECC Unbuffered UDIMM memory upgrade

Exact-match 8 GB DDR4 ECC UDIMM

This 8 GB DDR4-2933 module delivers PC4-23400 bandwidth at 1.2 V with CL21 latency. It uses a 1Rx8 unbuffered ECC layout on a 288-pin UDIMM so the memory controller recognises the rated speed and capacity immediately. The stick targets Supermicro X12SCZ-F and X12SCZ-TLN4F motherboards that require this precise rank, voltage and timing combination. Builders needing error-correcting memory for data-integrity workloads will find the spec match they need.

Verify motherboard population rules

Consult the Supermicro manual for supported capacities, approved DIMM population order and installation steps before ordering. The board accepts only 288-pin unbuffered ECC UDIMMs — not RDIMMs or SODIMMs — so confirm your slots follow the vendor-approved sequence. Systems that demand registered or load-reduced modules will not work with this unbuffered design. Buyers who need larger capacities per slot or a registered form factor cannot use this kit.

Thermals noise and power draw

Operating at 1.2 V without a heat spreader, the module runs cool and silent under normal loads. The low-voltage DDR4 design keeps power draw modest while ECC correction runs transparently in the background. No active cooling is required on the DIMM itself. Systems that rely on high-airflow chassis fans will see no additional acoustic contribution from this memory.
