Server memory module

This OWC DDR5 5600 ECC Registered RDIMM provides 128GB in a single 288-pin module. It is built for Gigabyte G363-SR0 and G493 series server platforms that require registered error-correcting memory. Standard desktop systems cannot use this module.

Capacity and headroom

A 128GB stick fills one slot at full rated speed of 5600 MT/s with CL46 latency at 1.1V. Workloads that fit within 128GB per channel run without swapping; larger datasets will require additional modules or higher-density parts not covered here.

Registered ECC requirement

The module is 4Rx4 registered ECC and will not operate in unbuffered or load-reduced slots. Buyers whose boards demand unbuffered or non-ECC DDR5 must choose a different product.

Questions about this item

Will this 128GB DDR5 5600 ECC Registered RDIMM work alongside my existing DDR5 ECC Registered modules in a Gigabyte G493-SB0?

Yes, provided the installed modules are also DDR5 5600 ECC Registered RDIMMs. This module is 4Rx4, CL46 at 1.1V and cannot be mixed with unbuffered or load-reduced ECC memory.

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

Check the system BIOS or a tool such as CPU-Z; it should report DDR5-5600 (PC5-44800) with CAS latency 46 and 1.1V on the SPD tab.

Does the package include only the 128GB 288-pin RDIMM or are any cables or brackets supplied?

The box contains the single 128GB DDR5 5600 CL46 4Rx4 288-pin 1.1V ECC Registered RDIMM. No cables, brackets or additional hardware are included.
