64GB DDR5 RDIMM kit for Supermicro H13SST-G

This 64GB kit contains four 16GB DDR5 4800 RDIMMs rated at CL40 and 1.10V. Registered ECC architecture with 1Rx8 organisation matches the Supermicro H13SST-G memory controller for full-capacity recognition at rated speed.

Suited for servers needing registered ECC memory

This kit suits administrators upgrading a Supermicro H13SST-G with validated registered ECC modules. Builders requiring UDIMM, SODIMM or non-ECC memory should look elsewhere, as the board demands 288-pin RDIMMs.

Straightforward 288-pin RDIMM installation

Install by following the motherboard manual for approved population order and capacity limits. Common issues arise when slots are filled out of sequence or when mixed-rank modules prevent the system from posting at full speed.

Questions about this item

What motherboard slot and memory type must my Supermicro H13SST-G have to accept these 288-pin DDR5 RDIMMs?

The kit uses 288-pin DDR5 RDIMM modules, so the board needs DDR5 RDIMM slots — standard for the H13SST-G — and the memory controller must support registered ECC operation.

If I keep existing DDR5 RDIMMs in other slots, will this 1Rx8 CL40 kit run at 4800 MHz alongside them?

The motherboard will clock all populated slots to the lowest common speed and timing; mixing ranks or latencies may force a lower frequency than 4800 MHz.

How can I confirm the full 64 GB kit is detected and running at DDR5-4800 CL40 with ECC active?

Check the BIOS memory summary or OS tools such as dmidecode for 64 GB total, 4800 MT/s data rate, CL40 latency, and ECC status reported as enabled.
