  • 288-pin RDIMM form factor fits the Supermicro H14SST-G DIMM slots exactly

Exact DDR5-4800 ECC RDIMM kit for Supermicro

This 384GB kit contains six 64GB registered DDR5 modules rated at 4800 MT/s with CL40 latency and 1.1V operation. It is built for administrators upgrading a Supermicro H14SST-G motherboard that requires 288-pin RDIMM population.

384GB across six slots with registered buffering

The 2Rx4 registered design lets the memory controller drive all six slots at full capacity without signal degradation. ECC corrects single-bit errors on the fly, protecting workloads that cannot tolerate silent corruption. Headroom ends when the board's maximum supported capacity or slot count is reached.

288-pin RDIMM form factor decides fit

Only motherboards that accept DDR5 288-pin registered DIMMs with 2Rx4 organisation and 1.1V signalling can use this kit. Systems requiring UDIMM, SODIMM, or a different voltage will not recognise the modules.

Questions about this item

Will this 6x64GB DDR5 4800 CL40 kit work with the DDR5 RDIMMs already installed in my Supermicro H14SST-G?

The kit is a 384GB 6x64GB DDR5 4800 CL40 1.1V 2Rx4 ECC Registered RDIMM set; match speed, voltage, rank and ECC type exactly to your existing modules and follow the motherboard manual for population order.

How can I confirm the 384GB kit is running at DDR5 4800 CL40 after installation?

Check the BIOS memory information or OS tooling for DDR5 4800 (PC5-38400) speed, CL40 latency, 1.10V voltage, 2Rx4 registered ECC status and full 384GB capacity across all six slots.

What comes in the box and do I need any extra parts for the H14SST-G?

The package contains the 384GB 6x64GB DDR5 4800 CL40 288-pin ECC RDIMM kit only; no cables, brackets or additional hardware are included, and the motherboard accepts the 288-pin RDIMM form factor directly.
