OWC 64GB DDR5 5600 ECC RDIMM

This 64GB DDR5 5600 module is an ECC Registered RDIMM built for workstations and servers. It fits the Gigabyte G593-SD0, G593-SD1, G593-SD2, G593-SX1 and H223-S10 platforms. The part number is 5R6D52R464GB.

Registered ECC limits

Registered ECC memory cannot be mixed with unbuffered or load-reduced DIMMs in the same system. It will not operate in standard desktop computers that require unbuffered non-ECC modules. JEDEC compliance ensures correct electrical signalling.

2Rx4 organisation

The module uses a 2Rx4 rank configuration at CL46 latency and 1.1V. This organisation must match the platform's memory controller requirements for the DIMM to initialise and run at the rated DDR5 5600 speed.

Questions about this item

Should I pick the 64 GB module or combine smaller DIMMs to reach the same total?

This is a single 64 GB DDR5 5600 CL46 2Rx4 registered ECC DIMM; add identical modules only if your Gigabyte G593 or H223 server has free 288-pin slots and the platform supports the total capacity.

What does the 5600 MT/s rating deliver inside a Gigabyte G593 or H223 server?

The module runs at the JEDEC-standard DDR5 5600 speed with CL46 latency at 1.1 V, giving the rated bandwidth when the system memory controller operates at that frequency.

Will the 288-pin DDR5 registered ECC interface work in a standard desktop motherboard?

No — this is a registered ECC RDIMM for workstation and server platforms such as the listed Gigabyte models; it is not compatible with unbuffered desktop memory controllers.
