Exact-match DDR5 upgrade for Supermicro H13DSH

This 256GB kit contains four 64GB DDR5-5600 RDIMMs built to the precise rank, voltage, and timing the H13DSH memory controller expects. The modules are 2Rx4 registered ECC running at 1.1V with CL46 latency so the board recognises full capacity at rated speed without manual tuning.

Registered ECC architecture offloads the controller

Registered buffering lets every slot run fully populated at full capacity while ECC corrects single-bit errors on the fly. The 288-pin RDIMM form factor matches the board's physical and electrical requirements exactly, preventing the compatibility issues that UDIMM or SODIMM modules would cause.

Handles large virtualisation and database workloads

Four ranks per channel give the platform maximum density for memory-intensive tasks such as virtualisation hosts or in-memory databases. The kit reaches its limit when the motherboard's maximum supported capacity or population rules are exceeded; consult the system manual for those boundaries before installation.

Questions about this item

Will the 2Rx4 ECC RDIMM modules need any firmware updates or scheduled replacement?

The DDR5 5600 CL46 1.10V registered DIMMs have no moving parts and require no firmware updates; they are rated for continuous server operation and only need replacement if a hardware fault occurs.

What limits sustained throughput on the 256GB kit running at DDR5 5600 PC5-44800?

Sustained throughput is capped by the DDR5 5600 MT/s data rate and CL46 latency of each 64GB 2Rx4 module when all four slots are populated on the Supermicro H13DSH.

How much heat and power does the 4x64GB 1.1V registered kit produce under 24/7 load?

Each 64GB 2Rx4 RDIMM runs at 1.10V without a heat spreader; the registered buffer reduces controller load, so total power draw and thermal output stay within standard DDR5 server limits.
