Exact DDR5-4800 RDIMM for Supermicro H14SSL-N

This 64GB module delivers DDR5-4800 (PC5-38400) speed at 1.1V with CL40 latency in a 288-pin registered ECC form factor. The 2Rx4 rank structure matches the memory controller expectations so the server recognises the full capacity and runs at the rated frequency.

Registered ECC architecture limits

Registered buffering offloads the memory controller, allowing every slot to be populated at full capacity while ECC corrects single-bit errors on the fly. DDR5-4800 is the maximum JEDEC speed this module supports; it will not operate at higher data rates. Motherboard population order and maximum supported capacity per slot still govern how many modules you can install.

Verify manual before ordering

Consult the Supermicro H14SSL-N manual for approved DIMM population sequences, maximum total memory, and any BIOS version requirements. Systems that require unbuffered UDIMMs or SODIMMs cannot use this 288-pin RDIMM. Buyers needing non-ECC memory or a different voltage should select another part.

Questions about this item

Should I pick the 64GB 2Rx4 kit or a different capacity for my Supermicro H14SSL-N?

Choose the 64GB 2Rx4 kit when your board's memory-population rules call for a registered ECC RDIMM at 1.1V with CL40 timing; other capacities or ranks may not be recognised at full speed.

What does the 4800 MT/s rating deliver once installed in the server?

The module runs at DDR5-4800 (PC5-38400) with CL40 latency, giving the memory controller the exact data rate and timing it expects for full-capacity operation.

How does the 288-pin RDIMM interface limit performance in practice?

The registered 288-pin RDIMM interface buffers address and command signals, allowing every slot to be populated at 4800 MT/s without overloading the memory controller.
