Exact DDR5 768 GB Kit for Supermicro H13SSL-N

This 768 GB kit contains six 128 GB DDR5 RDIMMs built to the precise rank, voltage and timing the H13SSL-N memory controller expects. It is intended for administrators who need the full registered ECC capacity this board supports.

Registered ECC 2Rx4 at 1.10 V and CL40

The modules run at DDR5 4800 (PC5-38400) with a 2Rx4 organisation, 1.10 V operating voltage and CL40 latency. Registered buffering and ECC are mandatory for this platform; UDIMM or non-ECC parts will not work.

Straightforward DIMM installation with manual checks

The 288-pin RDIMMs seat like any server memory, but the board’s population rules and maximum supported capacity must be verified in the Supermicro manual before installation. Skipping that step is the most common cause of unrecognised modules.

Questions about this item

Will this 4800 MHz kit actually run at 4800 MHz in my Supermicro H13SSL-N?

Yes, the kit is spec-matched to the H13SSL-N so the memory controller recognises the 2Rx4 registered ECC modules at their rated DDR5-4800 speed and CL40 timings.

What does PC5-38400 mean for this DDR5 memory?

PC5-38400 is the JEDEC designation for DDR5-4800 modules, confirming the data-rate and voltage the motherboard expects.

Will these 288-pin RDIMMs fit my Supermicro H13SSL-N motherboard?

Yes, the H13SSL-N requires 288-pin registered RDIMMs and this 6-module kit matches that exact form factor and pin-out.
