64GB DDR4 3200 ECC Registered RDIMM

This 64GB module uses DDR4 3200MHz PC4-25600 registered memory with ECC and a 2Rx4 dual-rank layout. It operates at 1.20V with CL22 latency and fits 288-pin RDIMM slots. The Micron chipset and Supermicro certification target server and workstation platforms that require registered ECC memory.

Suited for servers needing registered ECC modules

Systems that accept only unbuffered UDIMM memory cannot use this registered RDIMM. Buyers whose motherboards limit capacity per slot below 64GB or require a different speed grade should verify specifications before ordering.

Supermicro certification and lifetime warranty

The Supermicro certification confirms compatibility with validated Supermicro platforms. A-Tech supplies a lifetime warranty and United States based technical support for the module.

Questions about this item

What motherboard slot and DDR generation are required for this 288-pin DDR4 3200 module?

The module fits a DDR4 288-pin RDIMM slot and runs at 3200 MHz with 1.20 V power.

Will this 2Rx4 ECC registered DIMM work with my existing CL22 DDR4 3200 sticks?

It shares the same 3200 speed and CL22 latency, but the motherboard must support registered ECC and mixed-rank operation.

How can I confirm the 64 GB module is running at PC4-25600 after installation?

Check the BIOS or OS memory report for 3200 MT/s, CL22 timings, 1.20 V and ECC registered status.
