OWC 64 GB DDR4 3200 ECC RDIMM

This 64 GB DDR4 3200 ECC Registered RDIMM is built for Gigabyte G482 and G492 servers and workstations. It delivers error-correcting registered memory for workloads that demand data integrity and uptime. The single-module design fits 288-pin DDR4 slots in the listed platforms. It is not compatible with standard desktop PCs or unbuffered and load-reduced memory types.

Capacity and headroom

The 64 GB module provides substantial capacity for virtualization, large datasets and multi-user services. Running at PC4-25600 with CL22 latency, it handles heavy concurrent tasks before hitting limits. Backward compatibility with 2133, 2400, 2666 and 2933 MHz systems allows deployment in older slots without replacement. Mixing with unbuffered or load-reduced DIMMs is not supported.

Thermals noise and power

Operating at 1.2 V, the module draws minimal power and runs without a heat spreader in typical server airflow. Passive cooling keeps noise at zero while maintaining JEDEC thermal limits. The registered buffer reduces electrical load on the memory controller for stable long-term operation.

Questions about this item

Will this 64GB DDR4 3200 ECC registered RDIMM run alongside my existing 2133MHz or 2400MHz modules in a Gigabyte G482-Z53 server?

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

How can I verify the 64GB DDR4 3200 CL22 2Rx4 module is detected correctly after installing it in my G492-H80?

Check the system BIOS or UEFI during POST; it should report a single 64GB registered ECC DIMM running at 3200MT/s with CL22 timings at 1.2V.

Does the 3R2D42R464GB kit include only the memory module or are any cables or brackets supplied?

Only the 288-pin DDR4 ECC registered RDIMM is included; no cables, brackets or additional hardware are provided.
