Capacity and Form Factor

This kit delivers 512 GB of DDR5 server memory across eight 64 GB registered DIMMs. The 288-pin RDIMM modules use a 2Rx4 organization and operate at 1.1 V, matching the electrical and physical requirements of the Supermicro H13DSH motherboard.

DDR5-5600 Interface Limits

The PC5-44800 standard sets the maximum data rate at 5600 MT/s with a CAS latency of CL46. Registered buffering and ECC are mandatory for this platform, so unbuffered or non-ECC modules will not function. Full-slot population is supported only when every DIMM meets these exact timing and voltage specifications.

Workload Headroom

Eight ranks per channel provide the density needed for large virtualization clusters, in-memory databases, and high-throughput compute nodes. The registered architecture keeps signal integrity stable at full capacity, while ECC corrects single-bit errors on the fly. Systems requiring more than 512 GB or a different DIMM rank configuration will need a motherboard that supports higher densities.

Questions about this item

Should I choose this 512GB kit or a smaller capacity for my Supermicro H13DSH?

This kit provides eight 64GB modules for a total of 512GB. Select it when your workload needs maximum memory per socket and the board's population rules allow all slots to be filled with 2Rx4 registered DIMMs.

What does the 5600MHz rating mean once the modules are installed in the server?

The memory controller will run the kit at DDR5-5600 (PC5-44800) with CL46 latency at 1.1V, delivering the rated throughput as long as the motherboard firmware recognises the 2Rx4 registered configuration.

How does the 288-pin RDIMM interface affect compatibility and performance limits?

The 288-pin registered DIMM form factor is required by the H13DSH; the registered buffer lets all eight slots operate at full 5600MHz speed while ECC corrects single-bit errors, preventing the bandwidth drop seen with unbuffered modules in fully populated servers.
