Server-grade ECC registered DDR4

This 32 GB DDR4 3200 module is an ECC registered RDIMM built for Gigabyte MP72-HB0 MU72-SU0 MU92-TU1 MZ01-CE0 and MZ01-CE1 platforms. It targets administrators who need error-correcting memory for server, workstation or NAS workloads. Standard desktop boards cannot use this registered design and it must not be mixed with unbuffered or load-reduced DIMMs. The single 2Rx4 stick delivers 32 GB in one slot.

288-pin registered form factor

The module uses a 288-pin DDR4 interface at 1.2 V with CL22 timing and no heat spreader. Registered buffering places a register between the DRAM and the memory controller, reducing electrical load on the platform and allowing higher capacities per channel. Backward compatibility covers 2133 2400 2666 and 2933 MHz systems so the same DIMM can populate older slots. JEDEC and RoHS compliance ensures the stick meets industry electrical and environmental standards.

Verify registered ECC support

Before ordering confirm that your Gigabyte system lists ECC registered RDIMM support in its qualified vendor list. The platform must accept 2Rx4 organisation and 1.2 V operation at DDR4 3200 or a lower supported speed. Mixing this stick with unbuffered or load-reduced modules will prevent boot or cause instability. No desktop consumer motherboard can operate with this registered memory type.

Questions about this item

What DDR4 standard does the PC4-25600 3200MHz module follow, and what speed does it cap at in practice?

The module follows the JEDEC DDR4 PC4-25600 standard and runs at 3200MHz; it will down-clock to 2133MHz, 2400MHz, 2666MHz or 2933MHz if the platform requires a lower speed.

What physical slot and form factor does this 288-pin ECC Registered RDIMM need to fit?

It requires a standard 288-pin DDR4 DIMM slot in a server, workstation or NAS chassis; the registered design and 2Rx4 organisation mean it will not fit or function in unbuffered desktop boards.

How is the single 32GB RDIMM installed, and what step do people often get wrong?

Power down the system, open the chassis, align the notch on the 288-pin edge connector with the slot key, press firmly until both retention clips click, then verify the firmware recognises the full 32GB at 3200MHz; the common mistake is mixing this registered ECC module with unbuffered or load-reduced DIMMs, which prevents boot.
