Server-grade DDR5 RDIMM for Gigabyte R183-Z9x

This OWC module is a 64 GB DDR5 4800 CL40 ECC registered DIMM built for workstation and server platforms. It targets administrators upgrading or repairing Gigabyte R183-Z92 through R183-Z96 systems. The single 288-pin stick operates at 1.1 V and uses a 2Rx4 organisation. It is not compatible with standard desktop motherboards or with unbuffered or load-reduced memory types.

Registered ECC with 2Rx4 organisation

The registered buffer and on-die ECC are the defining specifications that decide fitment. These features allow the memory controller to address the 64 GB capacity reliably in multi-DIMM server configurations. Mixing this module with unbuffered or load-reduced DIMMs will prevent the system from posting. Buyers must confirm their platform requires registered ECC DDR5 before purchasing.

Steady throughput under sustained server loads

JEDEC-standard DDR5 4800 timing at CL40 delivers consistent bandwidth during long-running workloads such as virtualisation, database serving or NAS duties. The 1.1 V operating voltage helps maintain thermal stability across fully populated channels. Without a heat spreader, adequate chassis airflow is required to sustain rated performance over extended periods.

Questions about this item

What does the 4800 MT/s rating mean once the module is installed in a compatible Gigabyte server?

The module will run at 4800 MT/s, delivering PC5-38400 bandwidth with CL40 latency at the standard 1.1 V DDR5 voltage.

How does the 288-pin RDIMM form factor and registered ECC design affect what systems can use it?

It fits only DDR5 RDIMM slots that support registered ECC; it cannot be used in unbuffered desktop boards or mixed with load-reduced DIMMs.

What physical clearance is needed for this 288-pin DDR5 RDIMM in a Gigabyte R183-Z92 through R183-Z96 chassis?

The module has no heat spreader, so it occupies a standard low-profile DIMM height and requires only the normal DDR5 RDIMM slot spacing.
