OWC 32 GB DDR5 4800 ECC RDIMM

This 32 GB DDR5 module runs at 4800 MT/s with CL40 latency and 1.1 V operation. It is an ECC Registered DIMM built for workstations, servers and compatible Gigabyte platforms. The single 2Rx8 rank design fits a standard 288-pin slot. It will not work in standard desktop computers or alongside unbuffered memory.

Capacity and headroom for registered workloads

The 32 GB capacity suits virtualization hosts, database nodes and NAS appliances that need error correction. Registered buffering reduces electrical load on the memory controller, allowing larger populations per channel. Systems limited to lower densities or unbuffered DIMMs cannot use this module.

JEDEC compliance and warranty-safe upgrade

JEDEC-standard construction ensures the module meets OEM specifications without requiring BIOS tuning. ROHS compliance confirms restricted-substance adherence. The design targets Gigabyte H273-Z82, MZ33-AR0, MZ33-CP0, MZ73-LM0 and MZ73-LM1 platforms for validated compatibility.

Questions about this item

Will this 4800 CL40 DDR5 ECC Registered RDIMM run with my existing DDR5 ECC Registered modules in a Gigabyte H273-Z82?

Yes, if the installed modules are also DDR5 ECC Registered RDIMMs at 4800 MT/s and 1.1 V; you cannot mix registered with unbuffered or load-reduced DIMMs.

How do I confirm the 32 GB module is detected at 4800 MT/s with ECC active after installation?

Check the BIOS memory information screen — it should show 32 GB, DDR5-4800, CL40, 1.1 V and ECC enabled.

Does the box contain only the single 288-pin 2Rx8 RDIMM or are extra brackets or cables included?

Only the 32 GB DDR5 4800 CL40 2Rx8 288-pin 1.1 V ECC Registered RDIMM is supplied; no brackets, cables or additional parts are included.
