Single-module 128 GB DDR5 ECC RDIMM

This OWC module delivers 128 GB of DDR5 5600 memory in one 288-pin registered DIMM. It runs at 1.1 V with CL46 latency and 4Rx4 organisation. ECC and registered buffering make it suitable for workstation and server platforms that require error correction.

Check Gigabyte model and memory type before ordering

The module is validated for Gigabyte MS33-AR0, MS33-AR1, MS33-CP0, MS73-HB0 and MS73-HB2 systems. Your board must support DDR5 ECC registered RDIMMs; unbuffered or load-reduced DIMMs cannot be mixed with this part. Confirm the memory slots accept 288-pin registered modules.

Suits servers and workstations needing

Ideal for administrators expanding memory in compatible Gigabyte servers or workstations. Not for standard desktop PCs that only accept unbuffered non-ECC memory. Buyers who need unbuffered DIMMs or lower-capacity modules should look at other memory types.
