Server Memory Upgrade

This 128GB DDR4 ECC RDIMM is built for Gigabyte G292-Z46 and G482-Z51 through G482-Z54 servers. It provides registered error-correcting memory for workloads that require data integrity. The module will not work in standard desktop computers or with unbuffered or load-reduced DIMMs.

Capacity and Speed Limits

A single module delivers 128GB at 3200MHz with CL22 latency and 1.2V operation. It is backward compatible with 2133MHz, 2400MHz, 2666MHz and 2933MHz bus speeds. Systems needing more total memory must populate additional slots; this unit alone does not scale beyond its stated capacity.

Registered ECC Requirement

The module uses an 8Rx4 registered ECC design on a 288-pin DDR4 form factor. Compatibility is limited to the listed Gigabyte server models; it cannot be mixed with unbuffered or load-reduced memory types. Verify your platform requires registered ECC RDIMMs before ordering.

Questions about this item

Will this 128GB 8Rx4 ECC RDIMM work alongside my existing DDR4 2666MHz modules in a Gigabyte G482-Z52 server?

Yes, the module is backward compatible with 2133MHz, 2400MHz, 2666MHz and 2933MHz speeds, so it will run at the speed of your slowest installed DIMMs.

How can I confirm the 128GB DDR4 3200 ECC registered module is operating correctly after installing it in my G292-Z46?

Check the BIOS or UEFI memory information screen; it should report 128GB capacity, 3200MHz speed (or the downclocked speed), CL22 latency, 1.2V voltage and ECC Registered status.

Does the single 128GB 288-pin RDIMM ship with a heat spreader or any installation tools?

The module has no heat spreader and no tools are included; only the bare DIMM is supplied.
