OWC 32GB DDR5 4800 ECC RDIMM

This OWC module is a 32GB DDR5 4800 CL40 ECC Registered RDIMM built to JEDEC and RoHS standards. It operates at 1.1V with a 2Rx8 rank configuration on a 288-pin form factor. The part number is 4R8D52R832GB and the product is new.

Suited for Gigabyte R163 and R183 servers

The memory is validated for Gigabyte R163-Z30, R163-Z32, R163-Z35, R183-Z90 and R183-Z91 systems. It fits workstations, NAS units, servers and network switches that require registered ECC DDR5. Builders needing unbuffered or load-reduced DIMMs should look elsewhere because this module cannot be mixed with those types.

Single-module upgrade with lifetime support

The package contains one 32GB RDIMM and no additional accessories or software. OWC backs the module with a limited lifetime warranty and an advanced replacement program plus free technical support. The warranty-safe design meets or exceeds OEM specifications for compliant installations.

Questions about this item

What motherboard socket or chipset is required for this 288-pin DDR5 4800 ECC Registered RDIMM to function?

It is validated for Gigabyte R163-Z30, R163-Z32, R163-Z35, R183-Z90 and R183-Z91 systems that accept DDR5 ECC Registered memory.

Can this 32 GB 2Rx8 module be installed alongside existing unbuffered or load-reduced ECC DIMMs in the same server?

No — the manufacturer states it cannot be mixed with unbuffered or ECC load-reduced memory; all slots must use registered ECC modules.

How can I confirm the module is running at the rated PC5-38400 4800 MT/s CL40 after installation?

Check the BIOS or UEFI memory information screen; it should report DDR5 4800 speed and CAS latency 40 for the installed DIMM.
