Exact-fit server memory kit

This 576GB kit contains twelve 48GB DDR5 RDIMM modules built for the Supermicro H13SSL-N motherboard. It targets administrators who need the full 12-slot population recognised at rated speed without manual tuning. The registered ECC design matches the board's memory controller requirements precisely.

Registered ECC stability at full population

Registered buffering offloads the memory controller so all twelve slots operate at DDR5 6400 with CL52 timing and 1.1V. ECC corrects single-bit errors on the fly to prevent silent data corruption. The 288-pin RDIMM form factor fits only boards wired for registered DIMMs, not UDIMM or SODIMM layouts.

Upgrade from partial or lower-capacity

This kit replaces smaller matched sets or mixed-capacity populations that limit total addressable memory. The jump is worth it when workloads demand the full 576GB at native DDR5 6400 throughput. Buyers who need a different capacity, a UDIMM form factor, or non-ECC modules should look elsewhere.

Questions about this item

What DDR5 speed and data rate does this 576GB kit run at?

The modules operate at DDR5 6400 with a PC5 51200 data rate, matching the Supermicro H13SSL-N memory controller specification.

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

Each module is a 288-pin DDR5 RDIMM, the registered DIMM form factor required by the H13SSL-N motherboard.

How should the twelve 48GB RDIMMs be populated in the H13SSL-N?

Follow the motherboard manual for the approved DIMM population order; the kit is spec-matched to the board's memory-population rules.
