128 GB DDR5-4800 ECC RDIMM kit

This 128 GB kit contains two 64 GB DDR5-4800 registered ECC modules built for the Supermicro H13DSG-OM motherboard. Each DIMM runs at 1.1 V with CL40 latency and a 2Rx4 organisation, matching the board's registered memory requirement.

Registered DDR5 interface limits

Registered DDR5 RDIMMs buffer address and command signals so the memory controller can drive a fully populated channel at the rated 4800 MT/s. Unbuffered UDIMMs or SODIMMs will not function in this platform and the 288-pin keying prevents accidental insertion of the wrong module type.

Verify population rules first

Server memory support varies by model and BIOS revision; consult the Supermicro H13DSG-OM manual for approved capacities per slot, required DIMM installation order, and any firmware updates needed before installing this kit.

Questions about this item

Should I choose the 2 x 64 GB kit or a single 128 GB module for my Supermicro H13DSG-OM?

The kit provides two 64 GB RDIMMs that populate two slots and satisfy the board's registered DIMM population rules for full 128 GB capacity.

What does the 4800 MT/s rating mean once the memory is installed in the server?

The modules run at DDR5 4800 with CL40 latency and 1.10 V, delivering the exact speed and timing the motherboard's memory controller expects for stable operation.

How does the 288-pin RDIMM interface limit what I can install?

The 288-pin registered form factor is required by the H13DSG-OM; UDIMM or SODIMM modules will not fit or function in this server board.
