Supermicro H13DSG-OM DDR5 upgrade

This 256GB kit contains four 64GB DDR5 4800 Registered ECC RDIMMs built to the exact rank, voltage and timing the Supermicro H13DSG-OM motherboard expects. It targets administrators who need the full 256GB capacity recognised at rated speed without manual tuning.

DDR5 4800 RDIMM interface limits

The modules run at 4800 MT/s with CL40 latency at 1.1V, the baseline DDR5 server data rate. Registered buffering allows every slot to be populated while keeping the memory controller load manageable, but the standard caps frequency at this level unless the platform explicitly supports higher JEDEC bins.

256GB capacity and headroom

Four dual-rank 64GB DIMMs fill the board's supported slots and deliver 256GB of ECC-protected memory for virtualisation, databases or large in-memory workloads. Expanding beyond this kit requires a motherboard with additional DIMM sockets or higher-density modules that the platform must expressly qualify.

Questions about this item

Should I choose the 4x64GB kit or a different capacity for my Supermicro H13DSG-OM?

This kit provides 256GB total across four 64GB modules, matching the board's 288-pin RDIMM slots and registered ECC requirements for full-capacity recognition.

What does the DDR5-4800 CL40 rating deliver once installed in the server?

The modules run at 4800 MT/s with CL40 latency at 1.1V, giving the memory controller the exact timing and voltage it expects for stable operation at rated speed.

How does the registered ECC interface affect performance limits on this motherboard?

Registered buffering reduces electrical load on the controller so all four slots can run fully populated at 4800 MT/s, while ECC corrects single-bit errors to prevent silent data corruption.
