64GB DDR4 RDIMM for Servers

This 64GB DDR4 3200MHz CL22 ECC Registered DIMM is built for Supermicro platforms that require registered memory. The single-module design delivers high density in one 288-pin slot. It targets administrators who need maximum capacity per channel for virtualization or database workloads.

Upgrade from Smaller DDR4 Modules

Replacing lower-capacity RDIMMs with this 64GB module doubles or quadruples memory per slot. The jump is worth it when the motherboard supports 2Rx4 registered DIMMs at 3200MHz and the workload demands more simultaneous threads. Systems limited to lower speeds or unbuffered memory cannot use this module.

Fits Supermicro Certified Platforms

The module operates at standard 1.20V DDR4 voltage and requires a server board qualified for Supermicro MEM-DR464MC-ER32 certification. It frees additional DIMM slots for future expansion while delivering 64GB in a single registered stick. Builds needing unbuffered UDIMMs or non-ECC memory are not compatible.

Questions about this item

Does the 288-pin RDIMM form factor fit my Supermicro server DIMM slots?

Yes — this is a standard 288-pin DDR4 RDIMM that matches Supermicro server memory slots.

What is the correct orientation step when seating the 2Rx4 registered module?

Align the single key notch on the module with the slot ridge, press straight down until both side clips click, then verify the register LED is lit.

When should the 1.2 V ECC registered DIMM be replaced?

Replace it if the system logs uncorrectable ECC errors, fails memory diagnostics, or becomes unstable under sustained load.
