Exact-Match Server Upgrade

This NEMIX RAM kit delivers 768GB of DDR5 memory across 16 modules of 48GB each, built to the precise specifications the Supermicro H13SSF motherboard expects. Registered ECC RDIMM architecture with 2Rx8 organisation, 1.10V operation and CL40 timing ensures the memory controller recognises full capacity at the rated 4800MHz speed without manual tuning.

Registered ECC Stability

Each 288-pin RDIMM uses major-brand Samsung, Micron or Hynix ICs without a heat spreader, relying on the server chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller so all 16 slots can run fully populated, while on-die ECC corrects single-bit errors in flight to prevent silent data corruption and unexpected reboots in production workloads.

Population-Rule Dependent

The kit replaces or expands existing memory only when the motherboard manual confirms support for 16 x 48GB 2Rx8 Registered DIMMs at DDR5-4800; boards limited to fewer ranks, lower densities or UDIMM slots cannot use this configuration. Verify the approved DIMM population order and maximum supported capacity in your system documentation before purchase.

Questions about this item

What DDR5 speed and CAS latency does this 16x48GB kit run at on the Supermicro H13SSF?

The kit is rated for DDR5 4800 (PC5-38400) with CL40 latency, so the memory controller will recognise all 768GB at that speed and timing.

What physical slot type and form factor are required to install these 48GB modules?

Each module is a 288-pin Registered RDIMM; the board must provide DDR5 RDIMM slots, not UDIMM or SODIMM sockets.

In what order should the 16 RDIMMs be populated on the H13SSF to avoid a no-post condition?

Follow the motherboard manual's approved DIMM population sequence for 16 modules; skipping the prescribed slot order is the most common cause of a failed boot.
