Server memory upgrade

This 64GB DDR4 3200 ECC registered RDIMM is built for Gigabyte H262 and R292 server platforms. It targets administrators who need error-correcting, registered memory to maintain data integrity in multi-socket workloads. The single-module design lets you populate one slot at a time. Buyers using standard desktop boards or unbuffered memory cannot use this module.

Build integration

The 288-pin DIMM installs directly into the registered DIMM slots of the listed Gigabyte systems without adapters. JEDEC-standard 1.2V operation keeps the module within the platform power envelope. Backward compatibility with 2133, 2400, 2666 and 2933MHz buses allows mixed-speed populations if the firmware permits. It cannot be mixed with unbuffered or load-reduced DIMMs.

Thermals and power

Operating at the standard 1.2V DDR4 voltage, the module draws minimal power per slot. No heat spreader is fitted, so airflow across the PCB relies on the server chassis fans. Registered buffering adds slight latency at CL22 but reduces electrical load on the memory controller. Acoustic output is governed entirely by the system cooling solution.

Questions about this item

Will the single 64GB 2Rx4 RDIMM fill a channel on the Gigabyte H262-Z6A without exceeding the registered-DIMM limit per channel?

The module is a single 64GB 2Rx4 registered DIMM; the Gigabyte H262-Z6A supports registered ECC RDIMMs, so one module occupies one slot and stays within the platform's per-channel registered-DIMM capacity.

Does the lack of a heat spreader on this 1.2V DDR4-3200 CL22 module raise temperatures during continuous server workloads?

The module runs at the standard 1.2V JEDEC voltage for DDR4-3200 and is designed for server and workstation airflow; registered ECC RDIMMs without spreaders are commonly used in dense chassis where directed airflow keeps temperatures in spec.

Must the Gigabyte H262-Z6A already be populated with registered ECC memory, or can this 64GB RDIMM be the first module installed?

This 64GB DDR4-3200 ECC registered RDIMM can be installed as the first and only module in a compatible Gigabyte H262-Z6A, H262-Z6B, H262-ZL0, H262-ZL2 or R292-4S0 system; it does not require existing registered memory to function.
