NEMIX RAM 288GB 6x48GB DDR5 6400 CL52 1.1V ECC RDIMM Supermicro H14SST-GE memory upgrade

Exact-match DDR5-6400 kit for Supermicro H14SST-GE

This 288GB kit contains six 48GB Registered ECC RDIMMs built to the board's required 2Rx8 rank structure and 1.1V operating voltage. Each module runs at DDR5-6400 (PC5-51200) with CL52 latency so the memory controller recognises the full capacity at rated speed. The 288-pin RDIMM form factor matches the slots on the H14SST-GE motherboard.

Sustained-load stability from registered ECC

Registered buffering reduces electrical load on the memory controller, allowing all six slots to stay fully populated at full frequency without signal degradation. On-die ECC detects and corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots during continuous server workloads. The 1.1V default voltage keeps power draw consistent across long-running tasks.

2Rx8 rank layout is the decisive compatibility

The H14SST-GE memory population rules require this exact dual-rank x8 organisation; a different rank configuration will either not be recognised or will force the controller to down-clock the kit. Buyers whose boards call for 1Rx8 or 2Rx4 modules cannot use this kit. Verify the motherboard manual for approved DIMM population order before ordering.
