  • 64 GB capacity lets Supermicro H13DSH servers run larger workloads in a single module
  • DDR5 5600 speed (PC5-44800) delivers rated bandwidth without down-clocking
  • Registered ECC design corrects single-bit errors and keeps every slot stable at full population
  • 2Rx4 rank and 1.10 V match the board's memory-controller expectations exactly
  • 288-pin RDIMM form factor fits the H13DSH DIMM slots — no UDIMM or SODIMM confusion

Exact-match DDR5 RDIMM for Supermicro H13DSH

This 64 GB DDR5 5600 registered ECC module uses a 2Rx4 organization at 1.10 V with CL46 timing. It is built to the precise rank, voltage and latency the H13DSH memory controller expects so the system recognizes the full capacity and runs at the rated speed. The 288-pin RDIMM form factor matches the board's requirement and is not a UDIMM or SODIMM.

Capacity and headroom

A single 64 GB DIMM provides a large step up for memory-intensive workloads such as virtualization, databases or scientific computing. Registered buffering offloads the controller so every populated slot can operate at full capacity, while ECC corrects single-bit errors on the fly to prevent silent data corruption. The module runs out of headroom when the application's working set exceeds the installed capacity or when the platform's maximum supported memory per socket is reached.

DDR5 5600 interface limits

The DDR5 5600 (PC5-44800) interface sets the maximum transfer rate and the timing envelope the module operates within. CL46 latency and 1.10 V are fixed by the JEDEC standard for this speed grade, so tighter timings or higher frequencies are not available without platform support for overclocking. Population rules, maximum capacity per channel and supported ranks are defined by the motherboard firmware and must be verified in the system manual before installation.

Questions about this item

Will this 64GB DDR5-5600 2Rx4 RDIMM run at its rated speed alongside my existing DDR5 modules in the Supermicro H13DSH?

The module is an exact-match upgrade specified at DDR5 5600 (PC5-44800), CL46, 1.1V, 2Rx4 registered ECC. When populated according to the motherboard manual's DIMM order, the memory controller will recognize it at full capacity and rated speed.

How can I verify the memory is operating at DDR5 5600 with CL46 and ECC active after installation?

Enter the BIOS or use a hardware-information tool such as dmidecode or CPU-Z; confirm the reported speed shows 5600 MT/s, CAS latency 46, voltage 1.1V, and that ECC status reads enabled for the 64GB registered DIMM.

Does the package include only the 64GB DDR5 RDIMM, or are any brackets, cables or additional licences supplied?

The package content lists the 64GB DDR5 5600MHz PC5-44800 2Rx4 1.1V CL46 288-pin ECC RDIMM kit only; no heat spreader, mounting hardware, cables or software licences are included.
