OWC 128GB DDR5 ECC Registered RDIMM

This 128GB DDR5 5600 ECC Registered RDIMM is built for Gigabyte R263-S30, R263-S33, R263-S34, R263-SG0 and R283-S90 servers. It suits administrators who need maximum capacity per slot in registered memory configurations. It will not work in standard desktop computers or systems that require unbuffered or load-reduced DIMMs.

288-pin DDR5 module installs in compatible server

The module uses the standard 288-pin DDR5 form factor and operates at 1.1V with CL46 latency. Installation follows normal server DIMM procedures: align the notch, press firmly until the retention clips engage, and verify population rules in the system manual. Mixing this registered ECC module with unbuffered or load-reduced memory will prevent the system from posting.

128GB single-module capacity drives density

A single 4Rx4 128GB DIMM delivers the highest per-slot density available for these platforms, reducing the total number of modules needed to reach large memory footprints. Buyers who need smaller increments or plan to populate every slot with lower-capacity DIMMs should choose a different module size.

Questions about this item

How can I verify the module is running at 5600 MT/s with CL46 after installation?

Enter the system BIOS or UEFI and confirm the memory frequency shows 5600 MT/s and the CAS latency reads 46.

What comes in the box and is anything else required for installation?

The box contains a single 128 GB DDR5 ECC Registered RDIMM. No extra parts are needed; install it into a compatible 288-pin slot.

Which capacity should I choose for a Gigabyte R263-S30 server?

This module provides 128 GB in one DIMM. Add additional modules of the same specification to reach the total memory your workload requires.
