OWC 32GB DDR5 5600 ECC RDIMM

This is a single 32GB DDR5 5600 PC5-44800 CL46 2Rx8 288-pin 1.1V ECC Registered RDIMM module from OWC. It is built for workstation and server platforms that require registered memory with error correction. The part number is 5R6D52R832GB.

Suited for Gigabyte MS33 and MS73 systems

This module fits Gigabyte MS33-AR0, MS33-AR1, MS33-CP0, MS73-HB0 and MS73-HB2 platforms. It is not compatible with standard desktop computers. It cannot be mixed with unbuffered or load-reduced ECC memory. Buyers needing non-ECC or unbuffered DIMMs should look elsewhere.

32GB capacity for registered DDR5 workloads

The 32GB density provides headroom for virtualisation, database and NAS workloads on supported Gigabyte hardware. JEDEC-standard timings and 1.1V operation keep power draw predictable. Capacity limits are set by the motherboard's maximum supported memory and slot count.
