OWC 32GB DDR5 5600 ECC RDIMM

This OWC module delivers 32GB of DDR5 5600 memory with CL46 latency and 1.1V operation. It uses a 288-pin ECC registered DIMM form factor with 2Rx8 organisation. The part is validated for specific Gigabyte server and workstation platforms.

Suited for registered ECC server slots only

It fits Gigabyte H263-S62, H263-S63, H263-S64, MS03-6L0 and MS03-CE0 systems that require registered ECC DDR5. Builders using standard desktop boards, unbuffered ECC or load-reduced DIMMs cannot use this module.

Single 32GB rank provides substantial capacity

The 32GB density handles multi-threaded workloads and virtualisation buffers comfortably. Systems needing more than 32GB per slot or higher frequency than 5600 MT/s will require different modules.

Questions about this item

What motherboard and CPU combination must I already have to run this 5600 CL46 ECC RDIMM?

You need a Gigabyte H263-S62, H263-S63, H263-S64, MS03-6L0 or MS03-CE0 system that supports DDR5 ECC registered memory at 5600 MT/s and 1.1 V.

Can I keep my existing unbuffered ECC modules and add this 2Rx8 registered DIMM alongside them?

No — the manufacturer states this registered module cannot be mixed with unbuffered or load-reduced ECC memory.

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

Check the BIOS memory information or a tool such as CPU-Z; it should report DDR5-5600, CAS 46, 1.1 V and registered ECC operation.
