64 GB DDR4 ECC RDIMM for Gigabyte servers

This 64 GB DDR4 3200 PC4-25600 CL22 2Rx4 288-pin ECC Registered RDIMM is built for Gigabyte MZ32-AR0, MZ32-AR1, MZ71-CE0, MZ71-CE1 and MZ72-HB0 platforms. It targets administrators upgrading workstation or server memory capacity with a single JEDEC-compliant module.

Verify registered ECC support and slot availability

Confirm the host system accepts DDR4 288-pin ECC Registered DIMMs and cannot mix this module with unbuffered or load-reduced ECC types. Check that free DIMM slots exist and the platform firmware supports 64 GB per module at 3200 MHz or the listed backward-compatible speeds of 2133, 2400, 2666 and 2933 MHz.

Thermals and power in normal operation

The module runs at 1.2 V without a heat spreader, relying on chassis airflow for cooling. Registered buffering adds minimal latency while maintaining signal integrity under sustained server workloads. Power draw stays within standard DDR4 limits for 2Rx4 density during typical multitasking and virtualization tasks.

Questions about this item

Does the module come with a heat spreader or do I need to buy one separately?

The module ships without a heat spreader; no extra cooling hardware is included or required.

Should I choose the 64 GB CL22 2Rx4 module or a different capacity for my Gigabyte MZ32-AR0?

This single 64 GB DDR4 3200 CL22 2Rx4 registered ECC DIMM is the only variant listed for the MZ32-AR0 and matches the board's supported configuration.

Will the rated 3200 MHz speed actually run at 3200 MHz in a Gigabyte MZ71-CE1 server?

The module is rated DDR4 3200 CL22 and is backward compatible with 2933, 2666, 2400 and 2133 MHz; the final speed depends on the server's memory controller and BIOS settings.
