32GB DDR4 ECC RDIMM for Gigabyte Servers

This 32GB DDR4 3200 ECC Registered DIMM is built for Gigabyte G492-Z52, H242-Z10, H242-Z11, H252-3C0 and H252-Z10 servers and workstations. It operates at 1.2V with CL22 latency and a 2Rx4 organisation. The module is not compatible with standard desktop computers or unbuffered memory configurations.

Sustained Operation with ECC and Registered Buffer

The registered buffer reduces electrical load on the memory controller during continuous workloads, while ECC corrects single-bit errors to maintain data integrity over long periods. JEDEC-standard DDR4 3200 operation at 1.2V keeps power draw stable. Backward compatibility with 2133, 2400, 2666 and 2933MHz speeds allows the module to run reliably at lower frequencies if the system requires it.

Verify Registered ECC Support and Slot Availability

Confirm that your Gigabyte server platform accepts 288-pin DDR4 ECC Registered DIMMs and does not require Load Reduced or unbuffered modules. Ensure free DIMM slots exist for the desired capacity and that the system BIOS supports 32GB single-rank density per module. Mixing this registered module with unbuffered or Load Reduced memory will prevent boot.

Questions about this item

How much heat and power does the 1.2V ECC RDIMM draw when the server runs all day?

The module operates at 1.2V with no heat spreader, so it relies on the chassis airflow to stay cool during continuous operation.

What must the system already have to accept this 288-pin DDR4 3200 registered DIMM?

A Gigabyte G492-Z52, H242-Z10, H242-Z11, H252-3C0 or H252-Z10 platform with DDR4 RDIMM slots and a CPU memory controller that supports ECC registered memory.

Will this 32GB 2Rx4 CL22 stick work alongside my existing 2133MHz or 2400MHz DDR4 ECC RDIMMs?

Yes, it is backward compatible with 2133MHz, 2400MHz, 2666MHz and 2933MHz ECC registered DIMMs, though all modules will run at the speed of the slowest installed kit.
