64GB DDR4 ECC Registered RDIMM

This 64GB DDR4 3200 ECC Registered RDIMM is built for servers and workstations that require error-correcting registered memory. It fits Gigabyte MP72-HB0, MU72-SU0, MU92-TU1, MZ01-CE0 and MZ01-CE1 systems. Standard desktop computers cannot use this module type.

Replaces slower DDR4 or adds capacity

The module runs at 3200MHz with CL22 latency and 1.2V voltage. It is backward compatible with 2133MHz, 2400MHz, 2666MHz and 2933MHz DDR4 slots. The upgrade is worth it when your workload needs ECC integrity and the registered signal buffering this 2Rx4 design provides.

Verify registered ECC support and slot count

Confirm your system specifically supports DDR4 ECC Registered RDIMMs and cannot mix them with unbuffered or load-reduced DIMMs. Check available 288-pin slots and maximum per-slot capacity before ordering. This single 64GB stick requires a compatible registered memory controller.

Questions about this item

Does the 288-pin DDR4 RDIMM fit the DIMM slots on a Gigabyte MP72-HB0?

Yes, the module is a 288-pin DDR4 ECC Registered DIMM validated for the MP72-HB0, MU72-SU0, MU92-TU1, MZ01-CE0 and MZ01-CE1 platforms.

What is the correct installation sequence for this 2Rx4 registered module?

Power off the server, open the chassis, align the notch on the 288-pin edge connector with the slot key, press firmly until both retention clips lock, then populate additional slots per the platform's population guide.

When should the 64 GB DDR4 3200 module be replaced?

Replace the module if the system firmware reports uncorrectable ECC errors or if a larger capacity is required for the workload.
