Exact-match DDR5 kit for Supermicro H13DSH

This 768GB kit delivers six 128GB DDR5 RDIMM modules rated at 6400 MT/s with CL52 latency and 1.1V operation. The 2Rx4 registered ECC design matches the memory controller requirements so the system recognises full capacity and runs at rated speed.

Registered ECC architecture for full-slot stability

Registered buffering offloads the memory controller, allowing every slot to stay populated at full capacity while ECC corrects single-bit errors on the fly. This combination prevents silent data corruption and unplanned reboots in production workloads.

288-pin RDIMM form factor with no heat spreader

The modules use the 288-pin RDIMM layout required by the H13DSH motherboard and omit a heat spreader for dense slot spacing. Builders must consult the system manual for approved DIMM population order and supported capacity limits before installation.

Questions about this item

Will the 128 GB DDR5 RDIMM modules need replacement if I populate all six slots on the Supermicro H13DSH?

No scheduled replacement is required; the registered ECC design runs fully populated at the rated 6400 speed and 1.1 V for the server's service life.

What limit appears first when the kit runs continuously at DDR5 6400 CL52?

The memory controller's maximum supported capacity and population rules for the H13DSH are the first constraints; the modules themselves operate within their 1.1 V, CL52 specification.

How much heat and power does the 768 GB kit draw when the server runs all day?

Each 128 GB RDIMM operates at 1.1 V without a heat spreader; total power scales with the six modules at the standard DDR5 voltage, and registered buffering keeps per-slot load low.
