System-specific DDR5 ECC kit

This 64 GB kit contains four 16 GB DDR5-4800 registered ECC RDIMMs built to the exact rank, voltage and timing the Supermicro H14DST-F expects. Each module runs at 1.1 V with CL40 latency and a 1Rx8 organisation. The registered design lets every slot operate fully populated at rated speed.

Verify board population rules

Server memory support varies by model, so consult the H14DST-F manual for approved capacities, DIMM population order and installation steps before ordering. The board requires 288-pin registered RDIMMs — not unbuffered UDIMMs or SODIMMs. Confirm your chassis can accommodate four modules in the prescribed slots.

Lifetime replacement and US support

The kit ships as a matched set of four RDIMMs with no heat spreaders. A lifetime replacement warranty and free US-based technical support are included, so any defective module can be exchanged and configuration questions answered directly. No additional software or accessories are bundled.
