Server Memory Kit

This 256GB kit contains four 64GB DDR5 RDIMM modules built for the Supermicro H13SSL-N motherboard. It delivers registered ECC memory that the platform recognises at full capacity and rated speed.

Registered ECC RDIMM

The registered (buffered) architecture with ECC is the single specification that determines fit; the board requires 288-pin RDIMM modules and will not accept UDIMM or SODIMM alternatives.

256GB Capacity Headroom

Four 64GB 2Rx4 modules populate the supported slots at DDR5-6400 CL52 1.1V, providing the maximum density this kit offers. Workloads exceeding 256GB or needing a different rank configuration will require a separate memory solution.

Questions about this item

How does the DDR5-6400 speed translate to actual bandwidth inside a Supermicro H13SSL-N server?

The PC5-51200 rating means each 64 GB module delivers up to 51 200 MB/s of peak transfer rate, so a fully populated four-DIMM kit can move roughly 200 GB/s combined when the memory controller runs all channels at the rated 6400 MT/s.

What does the 288-pin RDIMM form factor guarantee for this Supermicro board?

The 288-pin Registered DIMM is the exact physical and electrical interface the H13SSL-N requires; it will not accept UDIMM or SODIMM modules, and the registered design lets the board run all slots fully populated at the rated 6400 MT/s.

Will the 64 GB dual-rank modules fit the standard DIMM slots on the H13SSL-N without clearance issues?

Yes, each module uses the standard 288-pin RDIMM height and has no heat spreader, so it fits the regular server DIMM sockets and leaves room for normal CPU cooler airflow.
