Exact-match 64 GB DDR5-5600 RDIMM

This 64 GB DDR5-5600 module delivers PC5-44800 bandwidth at 1.1 V with CL46 timing. It uses a 2Rx4 registered ECC layout on a 288-pin RDIMM form factor. The memory is built for the Supermicro H14SSF motherboard and targets servers that require registered error-correcting modules.

Straightforward DIMM seating

The RDIMM installs like any standard 288-pin DDR5 module: align the key notch, press firmly until the retention clips click, and follow the motherboard manual for population order. Common issues arise when slots are filled in the wrong sequence or when mixed ranks prevent the controller from training at the rated speed.

Verify board limits before ordering

Check the Supermicro H14SSF manual for maximum capacity per slot, approved population rules, and any BIOS version requirements for 64 GB registered DIMMs. Systems that only support unbuffered UDIMMs or lower densities will not recognise this module. Buyers needing non-ECC or consumer UDIMM memory should choose a different product.

Questions about this item

How do I confirm the 64GB DDR5 5600 CL46 ECC RDIMM is running at its rated speed after installation?

Enter the BIOS or UEFI on the Supermicro H14SSF and verify the memory frequency shows 5600 MT/s with CL46 timings and 1.1V. The registered ECC design lets the board train at full speed when populated per the manual.

What ships with the MR44800-924K1 kit and what must I source separately?

The package contains one 64GB 288-pin DDR5 5600 2Rx4 1.1V CL46 ECC Registered RDIMM. No heat spreader, cables, tools or additional modules are included.

Which capacity or rank should I choose for the Supermicro H14SSF if I need a single 64GB registered ECC module?

This 64GB 2Rx4 DDR5 5600 CL46 1.1V RDIMM matches the board's registered DIMM requirement. Select it when your configuration calls for one 64GB registered ECC DIMM per slot.
