Server Memory Upgrade

This is a single 128GB DDR5 5600 CL46 4Rx4 1.1V ECC Registered RDIMM module built to JEDEC standard. It uses a 288-pin form factor and carries the OWC part number 5R6D54R4128G for traceable identification.

Workstation and Server Builders

The module suits technicians upgrading or repairing the listed Supermicro X13 motherboards in workstations, NAS appliances, servers or network switches. It will not work in standard desktop computers and cannot be mixed with unbuffered or load-reduced ECC memory.

Registered ECC Requirement

The deciding specification is the registered ECC design, which the target motherboards require for operation. Installing unbuffered or non-ECC DIMMs instead will prevent the system from booting.
