Exact-match DDR5 kit for Supermicro H13SST-GC

This 128GB kit delivers two 64GB DDR5-4800 Registered ECC RDIMMs built to the precise rank, voltage and timing the board expects. The modules install as a matched pair so the server recognises full capacity at rated speed without manual tuning.

Registered ECC architecture for full-slot stability

Registered buffering offloads the memory controller, allowing every populated slot to run at 128GB while on-die ECC corrects single-bit errors before they reach production workloads. The 288-pin RDIMM form factor fits only boards wired for registered memory — not UDIMM or SODIMM slots.

Replaces smaller or slower DDR5 kits in this

Upgrading from lower-capacity or higher-latency DDR5 RDIMMs removes a memory bottleneck for virtualisation density and in-memory databases. The jump is worth it when your workload saturates the current DIMM count or requires ECC integrity at the full 128GB ceiling.

Questions about this item

What speed does the DDR5-4800 interface run at on the Supermicro H13SST-GC?

The kit is rated at DDR5 4800 (PC5-38400) and will operate at that speed when the motherboard's memory controller is configured for the rated frequency.

What physical slot and form factor do these modules require?

Each module is a 288-pin DDR5 RDIMM, so the board must provide standard 288-pin DDR5 DIMM slots; UDIMM or SODIMM slots will not accept them.

How should the two 64 GB RDIMMs be installed, and what step is often missed?

Populate the slots in the exact order listed in the Supermicro H13SST-GC manual; the step most often missed is following that specific population sequence for dual-rank registered DIMMs.
