128GB DDR5 RDIMM kit for Supermicro H13SSL-N

This 128GB kit contains eight 16GB DDR5 registered DIMMs built to the exact specifications of the Supermicro H13SSL-N motherboard. Each module runs at 4800MT/s with CL40 latency at 1.1V. The 1Rx8 organisation matches the board's memory controller expectations so the full capacity is recognised immediately.

288-pin registered form factor with ECC

The modules use the 288-pin RDIMM form factor required by the H13SSL-N; they are not compatible with UDIMM or SODIMM slots. Registered buffering reduces electrical load on the memory controller, allowing all eight slots to be populated at rated speed. On-die ECC detects and corrects single-bit errors to prevent silent data corruption in production workloads.

Replaces partial or mismatched DDR5 populations

Install this kit when the server currently runs with fewer than eight DIMMs, mixed ranks, or modules that force the controller to down-clock. The matched 1Rx8 rank structure and validated voltage restore full-channel bandwidth and stability. Builders who need a different total capacity or a UDIMM platform cannot use this registered kit.

Questions about this item

What DDR5 speed and PC5 rating does this 128GB kit run at?

The kit operates at DDR5 4800 with a PC5-38400 rating, matching the Supermicro H13SSL-N memory controller specification.

What physical form factor and pin count do these modules use?

Each 16GB module is a 288-pin Registered RDIMM, the exact form factor the H13SSL-N board requires.

How are the eight RDIMMs installed, and what step is often missed?

Follow the motherboard manual for the approved DIMM population order; skipping the prescribed slot sequence is the common error.
