Supermicro H13SST-G DDR5 upgrade

This 32 GB kit contains two 16 GB DDR5-4800 RDIMMs built to the exact rank, voltage and timing the Supermicro H13SST-G motherboard expects. Registered ECC architecture lets the memory controller drive every slot at full capacity while correcting single-bit errors on the fly. It is intended for administrators who need a drop-in, spec-matched memory expansion for this specific server platform.

DDR5-4800 RDIMM constraints

The modules operate at 4800 MT/s with CL40 latency at 1.10 V and use the 288-pin Registered form factor this board requires. Registered buffering offloads the controller so fully populated channels remain stable, but the kit will not fit UDIMM or SODIMM slots and cannot run on platforms limited to lower DDR5 speeds or different pinouts.

32 GB registered ECC headroom

Two 1Rx8 modules deliver 32 GB of error-correcting capacity, suitable for virtualization hosts, database nodes or compute workloads that benefit from registered stability. The fixed two-module kit cannot be expanded beyond 32 GB without adding further qualified RDIMMs, and the CL40 timing is set by the platform rather than user tuning. Buyers needing higher density per DIMM or non-ECC operation should look elsewhere.

Questions about this item

Should I choose the 2×16 GB kit or a single 32 GB module for the Supermicro H13SST-G?

The kit provides two 16 GB RDIMMs, letting you populate two channels for dual-channel bandwidth and full registered-ECC stability.

What does the DDR5-4800 CL40 rating mean once installed in the H13SST-G?

The modules run at 4800 MT/s with CAS latency 40 at 1.1 V, delivering the exact speed and timing the board's memory controller expects for full-capacity operation.

Does the 288-pin RDIMM interface limit how many modules I can install?

Registered RDIMMs offload the memory controller, so every supported slot on the H13SST-G can be fully populated at the rated 4800 MT/s without signal degradation.
