  • 64 GB capacity in a 4 × 16 GB kit scales server memory for demanding workloads
  • DDR5 5600 speed with CL46 latency delivers rated throughput for the Supermicro H14SSL-N platform
  • Registered ECC architecture offloads the memory controller and corrects single-bit errors for enterprise stability
  • 1 V operation at 1Rx8 rank matches the board's exact voltage and population requirements
  • 288-pin RDIMM form factor ensures correct fitment in the motherboard's registered DIMM slots

Exact-match DDR5 upgrade kit

This 64 GB kit contains four 16 GB DDR5-5600 modules built to the CL46 1.10 V 1Rx8 Registered ECC specification the Supermicro H14SSL-N memory controller expects. It is for administrators who need to populate all available slots with validated RDIMMs so the server runs at full rated capacity without timing mismatches.

Straightforward RDIMM installation

Each 288-pin module keys into the board's DDR5 RDIMM slots in the population order shown in the Supermicro manual; the registered buffer reduces electrical load so all four slots run stably at 5600 MT/s. The usual issue is mixing ranks or voltages — this kit avoids that by supplying identical 1Rx8 1.10 V sticks — but skipping the manual's slot sequence can still leave capacity unrecognised.

Verify your H14SSL-N configuration

Confirm the motherboard revision supports 64 GB total and the approved DIMM population order before ordering. The board requires Registered ECC DDR5 RDIMMs — UDIMMs, SODIMMs or non-ECC modules will not work — and the BIOS must be at a version that enables full-speed operation for a four-module 1Rx8 layout.

Questions about this item

How can I verify the kit is running at DDR5-5600 CL46 after installation?

Check the BIOS or UEFI memory information screen; it should report 5600 MT/s, CL46 timings, 1.10 V and registered ECC mode for all four slots.

What ships with the kit and is anything else required?

The box contains four 16 GB DDR5 288-pin RDIMMs totalling 64 GB; no extra cables, brackets or cooling parts are included or needed.

Which capacity kit should I choose for a Supermicro H14SSL-N?

This 64 GB (4 × 16 GB) kit matches the board's 288-pin registered ECC DDR5-5600 specification; select it when you need 64 GB across four slots.
