Server memory upgrade

This 32GB DDR4 ECC registered DIMM is built for Gigabyte G482-Z53, G482-Z54, G492-H80, G492-HA0 and G492-Z51 servers and workstations. It delivers error-correcting, registered performance at 3200MHz for 24/7 infrastructure workloads. The module is not compatible with standard desktop computers.

Compatibility check

Verify that your system requires 288-pin DDR4 ECC registered memory and supports 2Rx4 organisation at 1.2V. The module will not work with unbuffered or load-reduced ECC DIMMs, so existing memory must match this specification. Confirm the motherboard accepts PC4-25600 speed or one of the listed backward-compatible speeds.

Build integration

Install the module into an available RDIMM slot to add 32GB of registered capacity without mixing memory types. JEDEC and RoHS compliance ensures a warranty-safe upgrade for extending server life or populating a new build. The single-DIMM design leaves remaining slots free for future expansion.

Questions about this item

Does the module arrive as a single 32GB stick or a kit?

It is a single 32GB DDR4 3200 ECC Registered RDIMM. No extra cables or brackets are required; just an available 288-pin slot in a compatible server or workstation.

Should I pick this 32GB 3200 CL22 2Rx4 1.2V module or a different capacity?

This part number 3R2D42R432GB delivers 32GB at DDR4 3200 with CL22 latency and 2Rx4 organisation. Choose it when your Gigabyte G482-Z53, G482-Z54, G492-H80, G492-HA0 or G492-Z51 needs a registered ECC DIMM of this exact spec.

Will the rated 3200MHz speed actually run at 3200MHz in my Gigabyte G482-Z53?

The module is JEDEC-standard PC4-25600 CL22 at 1.2V. It will operate at 3200MHz if the platform supports that speed; otherwise it downclocks automatically to 2933, 2666, 2400 or 2133MHz while keeping ECC registered operation.
