NEMIX RAM 256GB (2x128GB) DDR5-4800 ECC RDIMM CL40 2Rx4 Supermicro X14SDV-20C-SP3F memory upgrade

Server Memory Kit

This 256GB kit contains two 128GB DDR5 RDIMM modules built for the Supermicro X14SDV-20C-SP3F motherboard. Registered ECC architecture and a 2Rx4 organisation let the memory controller address full capacity across every populated slot. The modules run at 4800MHz with CL40 timing at 1.1V, matching the board's native specification. It is intended for administrators who need maximum registered capacity on this specific platform.

Sustained Operation

Registered buffering reduces electrical load on the memory controller so all slots remain stable when fully populated under continuous workloads. ECC circuitry detects and corrects single-bit errors in real time, preventing silent data corruption during long-running compute or database tasks. The 1.1V operating voltage keeps power draw consistent across extended duty cycles. No heat spreader is fitted, so chassis airflow must handle thermal dissipation.

Installation Notes

The 288-pin RDIMM form factor fits only registered DIMM slots; UDIMM or SODIMM sockets will not accept these modules. Population order follows the motherboard manual's approved sequence, which varies by CPU configuration and must be verified before installation. Mixing ranks or capacities can prevent the system from recognising the full 256GB. Buyers who need a different capacity or unbuffered memory should select another kit.
