Server-grade DDR5 ECC module

This 128GB DDR5 4800 CL40 4Rx4 registered DIMM delivers error-correcting memory for Gigabyte G293-Z42, G293-Z43, G363-ZR0, G493-ZB0 and G493-ZB1 servers. It operates at 1.1V and meets JEDEC PC5-38400 specifications for workstation and NAS workloads. The single-module design adds maximum capacity per slot without mixing buffer types.

Direct slot installation only

Align the 288-pin key with the registered DIMM socket and press until the ejector clips engage; no heat spreader means clearance is minimal. The module will not function in unbuffered or load-reduced slots, and mixing it with non-registered memory causes boot failure. Verify the platform requires 4Rx4 registered ECC before fitting.

Suits Gigabyte server refreshes

IT teams extending G293 or G493 fleets gain 128GB per slot at native DDR5 4800 speeds. Builders needing unbuffered desktop memory, consumer overclocking profiles or load-reduced ECC should select a different module type. The registered design and 4Rx4 organisation limit use to compatible server mainboards only.

Questions sur cet article

How can I confirm the 128GB DDR5 4800 module is running at CL40 1.1V after installation?

Enter the server BIOS or use a hardware monitoring tool to verify the memory speed reads 4800 MT/s, CAS latency 40 and voltage 1.1V for the installed DIMM.

What ships with the OWC 4R8D54R4128G module and what must be sourced separately?

The box contains a single 128GB 288-pin DDR5 ECC Registered RDIMM; no heat spreader or additional hardware is included, so any required cooling or extra DIMMs must be purchased separately.

Which Gigabyte server models are validated for this 4Rx4 128GB DDR5 4800 RDIMM?

The module is qualified for Gigabyte G293-Z42, G293-Z43, G363-ZR0, G493-ZB0 and G493-ZB1 systems.
