Purpose-Built Server Memory Kit

This 512GB kit contains four 128GB DDR5 RDIMM modules built for the Supermicro H13SSH-E motherboard. It targets administrators who need the full registered-ECC capacity that board supports for virtualisation, database or compute workloads.

Registered DDR5 Constraints

The modules run at DDR5-4800 with CL40 timing at 1.1V and use a 2Rx4 organisation. Registered buffering and ECC are mandatory on this platform; UDIMM or non-ECC parts will not function, and mixing ranks or voltages can prevent the system from posting.

Pre-Installation Verification

Confirm the H13SSH-E manual for approved DIMM population order and maximum capacity per channel before ordering. The board requires 288-pin RDIMMs; SODIMM or 288-pin UDIMM form factors are physically incompatible and will not seat.

Questions about this item

Should I pick the 512GB 4x128GB kit or a smaller capacity for my Supermicro H13SSH-E?

The 512GB 4x128GB kit fills all four DIMM slots with 2Rx4 registered ECC modules at DDR5-4800 CL40 1.10V, matching the board's population rules for full-capacity operation.

What does DDR5-4800 CL40 mean for real-world throughput in this server?

The modules run at 4800 MT/s with 40-cycle CAS latency at 1.10V, delivering the rated PC5-38400 bandwidth when the memory controller drives all four ranks at spec.

How does the 288-pin RDIMM interface limit speed or capacity on this motherboard?

The 288-pin registered DIMM format is required by the H13SSH-E; it enables full 512GB capacity across four slots at DDR5-4800, while unbuffered or SODIMM modules would not be recognised.
