64GB DDR5-6400 RDIMM for Supermicro H13SSW

This 64GB DDR5 6400MHz PC5-51200 module is built for the Supermicro H13SSW motherboard. It uses a 288-pin Registered ECC RDIMM form factor with CL52 latency and 1.1V operation. The 2Rx4 rank configuration matches the board's memory controller expectations so the full capacity is recognised at rated speed. It is intended for server administrators who need exact-fit registered ECC memory for this platform.

Installation and common issues

The module installs like any 288-pin RDIMM: align the notch, press evenly until the retention clips lock, and follow the motherboard manual's population order. Because it is a Registered DIMM it will not work in slots wired for UDIMM or SODIMM. Problems usually arise when the DIMM sequence does not match the manual, when mixed ranks prevent full-speed operation, or when the BIOS has not been updated to support the full memory map.

Pre-order checks for your server

Verify that your H13SSW revision supports 64GB per slot and the total capacity you plan to install. Confirm the approved DIMM population sequence for 2Rx4 Registered modules in the system manual. Ensure the BIOS version listed for DDR5-6400 support is installed or can be updated before the modules arrive. Registered ECC RDIMMs are required; unbuffered or non-ECC memory is not compatible with this board.

Questions about this item

How can I confirm the 64GB DDR5 6400 CL52 module is running at its rated speed after installation?

Enter the system BIOS or UEFI and verify the memory frequency shows 6400 MT/s with CL52 timings at 1.10 V; the Supermicro H13SSW should also report the full 64 GB capacity per DIMM during POST.

What ships in the box and are any extra parts required for the Supermicro H13SSW?

The package contains one 64 GB 288-pin DDR5 6400 CL52 2Rx4 1.10 V ECC Registered RDIMM; no additional cables, brackets or cooling accessories are needed for installation on the H13SSW motherboard.

Which capacity or rank option should I choose for a fully populated H13SSW?

This listing provides a single 64 GB 2Rx4 Registered ECC RDIMM; select the quantity that matches your board's supported DIMM population rules and maximum capacity per slot as detailed in the Supermicro H13SSW manual.
