Server ECC Memory Upgrade

This OWC module is a 32GB DDR4 3200 PC4-25600 CL22 2Rx4 288-pin ECC Registered RDIMM. It is built for Gigabyte R272-Z34, R281-Z91, R281-Z92, R281-Z94 and R282-2O0 servers or workstations. The part number is 3R2D42R432GB and it operates at 1.2V.

Registered DIMM Constraints

ECC Registered memory runs on server and workstation platforms only. It will not work in standard desktop computers and cannot be mixed with unbuffered or ECC load-reduced modules. The module is backward compatible with 2133MHz, 2400MHz, 2666MHz and 2933MHz speeds.

Platform Verification Required

Confirm your system is one of the listed Gigabyte models before ordering. Verify the motherboard accepts 288-pin DDR4 Registered ECC RDIMMs and that you are not combining this stick with unbuffered or load-reduced memory. Check available DIMM slots for a single 32GB module.

Questions about this item

Is the 32GB 2Rx4 module the only capacity offered for these Gigabyte servers?

This listing is for a single 32GB DDR4 3200 PC4-25600 CL22 2Rx4 288-pin ECC Registered RDIMM. The supplier title confirms compatibility with Gigabyte R272-Z34, R281-Z91, R281-Z92, R281-Z94 and R282-2O0 systems.

Will the CL22 latency at 3200MHz actually run at that speed in a Gigabyte R281-Z92?

The module is rated DDR4 3200 (PC4-25600) with CAS latency 22 at 1.2V. It is backward compatible with 2133MHz, 2400MHz, 2666MHz and 2933MHz speeds, so the final frequency depends on the server's memory controller.

Does the ECC Registered RDIMM interface limit the maximum throughput to PC4-25600?

Yes, the module conforms to the JEDEC DDR4 PC4-25600 standard, which caps the data rate at 3200MT/s. The registered buffer adds one cycle of latency but does not change that peak bandwidth figure.
