Server-grade ECC RDIMM

This single 64GB DDR4 3200 ECC registered DIMM is built for Gigabyte R182-Z90, R182-Z91, R182-Z92, R182-Z93 and R262-ZA0 servers and workstations. It delivers 288-pin registered operation with CL22 latency at 1.2V for error-correcting workloads.

Thermals and power draw

The module runs at standard JEDEC 1.2V without a heat spreader, relying on chassis airflow for cooling in typical server configurations. Registered buffering adds minimal electrical load while maintaining signal integrity at 3200MHz across supported platforms.

Compatibility constraints

This RDIMM will not work in standard desktop computers and cannot be mixed with unbuffered or load-reduced ECC memory. It backs down to 2133MHz, 2400MHz, 2666MHz or 2933MHz when installed in slower systems.

Questions about this item

How do I install this 288-pin DDR4 ECC RDIMM in a Gigabyte R182-Z90 server, and what step is often missed?

Power down, open the chassis, align the notch on the module with the slot key, press firmly until both retention clips click, then verify in BIOS that ECC Registered mode is enabled — skipping the BIOS check is the common oversight.

What maintenance or replacement will this 64GB 2Rx4 module need over its service life?

No scheduled maintenance is required; the module has no heat spreader or moving parts, so replacement is only necessary if a memory test reports correctable ECC errors that exceed the platform threshold.

What limit appears first when this CL22 1.2V RDIMM runs sustained workloads in a Gigabyte R262-ZA0?

The CAS latency of 22 cycles at 3200 MT/s sets the timing ceiling; sustained throughput is bounded by that latency before thermal or voltage limits are reached.
