Exact-match DDR5-4800 kit for Supermicro H13SSF

This 384 GB kit contains eight 48 GB DDR5 ECC Registered RDIMMs running at 4800 MT/s with CL40 timing at 1.1 V. It is built for administrators who need to fully populate the Supermicro H13SSF motherboard with memory the controller recognises at rated speed and capacity.

Registered ECC RDIMM build for full-slot stability

Each module uses a 288-pin RDIMM form factor with 2Rx8 organisation and no heat spreader. Registered buffering reduces electrical load on the memory controller so all eight slots can run populated, while on-die ECC corrects single-bit errors before they reach the operating system.

Replaces partial or slower DDR5 configurations

The kit upgrades systems running fewer modules, lower capacities, or mixed-rank DIMMs that force the controller to down-clock. The jump is worth it when the workload demands the full 384 GB at native DDR5-4800 throughput without population compromises.

Questions about this item

What speed and latency does this DDR5 RDIMM kit run at?

The kit operates at DDR5-4800 (PC5-38400) with CL40 latency at 1.1V, the exact timing the Supermicro H13SSF memory controller expects for full rated performance.

Which DIMM slots and form factor does the Supermicro H13SSF require for this 288-pin kit?

The board requires 288-pin Registered RDIMMs; the eight 48GB modules must be installed in the specific slot population order listed in the H13SSF manual to reach 384GB.

What is the correct installation sequence for all eight modules on the H13SSF?

Follow the motherboard manual's exact DIMM population order; the step most often missed is populating slots in the prescribed sequence rather than filling adjacent sockets first.
