Targeted Server Memory Upgrade

This 64GB DDR5 5600 ECC Registered RDIMM is built for Supermicro X13 series motherboards including the X13SET-PT, X13SEVR-SP13F, X13SEW-F and X13SEW-TF. It serves workstations, NAS systems, servers and network switches that require registered error-correcting memory. The module will not work in standard desktop computers.

Straightforward DIMM Installation

Insert the 288-pin module into an available DDR5 RDIMM slot and secure the retention clips; no heat spreader is present so clearance is minimal. The most common issue is mixing this registered 2Rx4 DIMM with unbuffered or load-reduced ECC memory, which the manufacturer explicitly warns against.

Verify Platform Compatibility First

Confirm your motherboard is one of the four listed Supermicro models and that the system BIOS supports DDR5 5600 registered DIMMs. Check that existing memory uses the same registered ECC type and 1.1V operating voltage to avoid mismatched ranks or voltage conflicts.

Questions about this item

How can I confirm the 64GB DDR5 5600 module is running at CL46 1.1V after installation?

Enter the system BIOS or UEFI and check the memory information screen; it should report 5600 MT/s, CAS latency 46 and 1.1 V for the installed DIMM.

What comes in the box and what must be sourced separately for the OWC 64GB DDR5 ECC RDIMM?

The package contains one 64GB 288-pin DDR5 5600 CL46 2Rx4 1.1V ECC registered DIMM; no cables, tools or additional modules are included.

Which capacity and rank should I choose for a Supermicro X13SET-PT that needs a single 64GB registered ECC module?

Select the 64GB 2Rx4 DDR5 5600 CL46 1.1V registered ECC RDIMM — it matches the motherboard's qualified memory list exactly.
