64 GB DDR5 RDIMM kit for Supermicro H13SST-G

This 64 GB kit contains two 32 GB DDR5 registered ECC modules built for the Supermicro H13SST-G motherboard. It targets administrators who need to populate every DIMM slot with validated registered memory that runs at the board’s rated speed without manual tuning.

2Rx8 registered ECC at 1.1 V CL52

Each module is a 288-pin DDR5 RDIMM organised as 2Rx8, operating at DDR5 6400 (PC5-51200) with a CAS latency of 52 at 1.1 V. The registered buffer and on-die ECC let the memory controller drive a fully populated configuration while correcting single-bit errors before they reach the operating system.

Fits Supermicro H13SST-G 288-pin RDIMM slots

The kit matches the board’s required 288-pin registered form factor and population rules, freeing you from mixing unbuffered or SODIMM modules that the platform cannot recognise. Verify the motherboard manual for approved slot order and maximum supported capacity before installation.

Questions about this item

Will the 6400 MT/s speed run at that rate on the Supermicro H13SST-G?

The kit is specified at DDR5-6400 (PC5-51200) with CL52 timings. When installed in the H13SST-G, the memory controller will recognize the exact rank, voltage and timing profile, allowing the modules to operate at their rated 6400 MT/s speed.

Does the 288-pin RDIMM form factor match the board's DIMM slots?

Yes. The H13SST-G requires 288-pin Registered (RDIMM) DDR5 modules. This kit uses that exact form factor — not UDIMM or SODIMM — so it fits the board's DIMM slots and follows the motherboard's population rules.

What physical clearance do the 32 GB modules need inside the chassis?

Each 32 GB module is a standard-height 288-pin RDIMM without a heat spreader. They occupy one DIMM slot each and require only the normal vertical clearance for a registered DDR5 DIMM in a server chassis.
