  • 256 GB total capacity from four 64 GB modules for dense server workloads
  • DDR5 4800 speed with CL40 latency delivers rated bandwidth for the platform
  • 1 V registered ECC RDIMM architecture reduces controller load and corrects single-bit errors
  • 2Rx4 288-pin form factor matches Supermicro H13SST-G population rules exactly
  • Lifetime replacement warranty with US-based technical support included

Capacity and configuration

This 256GB kit contains four 64GB DDR5 RDIMMs rated at 4800MHz with CL40 timings and 1.1V operation. It is built for the Supermicro H13SST-G motherboard and uses registered ECC modules with a 2Rx4 organisation.

Upgrade path and fit

The kit replaces smaller or slower DDR5 RDIMM sets when the board requires fully populated slots at registered speeds. The jump is worth it when your workload needs the full 256GB capacity and the memory controller demands exact rank, voltage and timing alignment.

Workload headroom

Registered ECC architecture keeps every slot stable at full population while correcting single-bit errors before they affect production. Capacity runs out when the application footprint exceeds 256GB or when the platform requires a higher data rate than 4800MHz.

Questions about this item

Will these 288-pin RDIMMs fit the Supermicro H13SST-G memory slots?

Yes, the 288-pin DDR5 RDIMM form factor matches the slots on the H13SST-G motherboard.

What is the correct population order for the four 64 GB modules on this board?

Consult the Supermicro H13SST-G manual for the approved DIMM population sequence; the kit must be installed in the exact order the board specifies.

Do these modules have a heat spreader that could need cleaning or replacement later?

No, the modules are supplied without a heat spreader, so there is no spreader to maintain or replace.
