Server ECC RDIMM for Gigabyte R183

This 64GB DDR5 module is built for workstations and servers that require registered ECC memory. It fits the Gigabyte R183-S95, R183-S96, R183-S97, R183-SF0 and R183-SF1 platforms. It will not work in standard desktop computers and cannot be mixed with unbuffered or load-reduced DIMMs.

64GB capacity at DDR5 5600 speed

The single module delivers 64GB of registered memory running at PC5-44800 with CL46 latency and 1.1V operation. It provides ample headroom for virtualisation, large datasets and multi-user workloads. Capacity limits are set by the host system’s maximum supported memory per slot and total population rules.

Registered ECC with 2Rx4 organisation

The 2Rx4 rank configuration and registered buffer are the defining specifications that determine compatibility. Only systems designed for DDR5 registered ECC RDIMMs can accept this module. Buyers needing unbuffered ECC or standard desktop memory must select a different product type.

Questions about this item

Will this 64 GB DDR5 5600 ECC RDIMM run alongside the registered memory already installed in my Gigabyte R183-S96?

Yes — this module is a 2Rx4 DDR5-5600 ECC Registered DIMM, and the manufacturer highlights state it cannot be mixed with unbuffered or load-reduced ECC memory, so it must be paired with identical registered ECC modules.

How can I verify the module is operating at DDR5-5600 CL46 1.1 V after installation?

Check the BIOS or UEFI memory information screen; it should report 5600 MT/s, CAS latency 46 and 1.1 V for the installed DIMM.

Does the 64 GB DDR5 ECC RDIMM ship with a heat spreader or any extra accessories?

The specifications list no heat spreader and the box contains only the single 288-pin registered DIMM; no cables, brackets or additional components are included.
