64 GB DDR4 3200 ECC RDIMM for Gigabyte servers

This 64 GB DDR4 3200 ECC registered RDIMM is built for Gigabyte R262-ZA1, R262-ZA2, R271-Z00, R272-P30 and R272-P31 systems. It delivers error-correcting registered memory required by workstation and server platforms. The module will not work in standard desktop computers and must not be mixed with unbuffered or load-reduced DIMMs.

Sustained throughput at 3200 MT/s with CL22

At its rated 3200 MT/s speed and CL22 latency the module maintains steady data rates during long compute jobs. It also runs at 2133, 2400, 2666 or 2933 MT/s when the platform requires a lower frequency. The registered buffer helps keep signal integrity stable across all supported speeds.

Low-voltage operation without a heat spreader

The DIMM runs at 1.2 V and has no integrated heat spreader, relying on chassis airflow for cooling. Power draw stays modest during typical server workloads, and the lack of a spreader keeps the module height low for dense configurations. Acoustic output is determined by the system fans rather than the memory itself.

Questions about this item

How much power does the 1.2V 64GB DDR4 3200 ECC RDIMM draw when running continuously in a server?

The module operates at 1.2 volts, the standard DDR4 voltage, so power draw stays within JEDEC limits for registered DIMMs.

What motherboard slot and chipset support is required to install this 288-pin registered ECC module?

It fits a 288-pin DDR4 RDIMM slot and is validated for Gigabyte R262-ZA1, R262-ZA2, R271-Z00, R272-P30 and R272-P31 platforms.

Will this CL22 3200MHz registered DIMM run stably alongside existing 2133MHz or 2400MHz ECC memory?

Yes, backward compatibility is specified for 2133, 2400, 2666 and 2933 MHz speeds; the system will clock all modules to the lowest common speed.
