64GB DDR4 3200MHz ECC RDIMM

This 64GB DDR4 module runs at 3200MHz with CL22 latency and 1.20V operation. It uses a 2Rx4 registered ECC design built on Samsung chipset and carries Supermicro certification for validated compatibility. The 288-pin RDIMM form factor fits server and workstation platforms that require registered memory.

For servers needing registered ECC capacity

This module suits administrators expanding memory in Supermicro-qualified systems that support DDR4 3200 registered DIMMs. Builders whose platforms only accept unbuffered UDIMMs or require a different voltage should look at other memory types.

Sustained load stability with registered ECC

The registered buffer reduces electrical loading on the memory controller during continuous operation, while ECC corrects single-bit errors in real time. Samsung 2Rx4 organisation delivers consistent throughput at 3200MHz under prolonged workloads without the signal integrity strain seen on unbuffered alternatives.

Questions about this item

Will this 64GB DDR4 3200MHz RDIMM work in a motherboard that only has 288-pin DDR4 slots?

Yes, this module uses the standard 288-pin DDR4 RDIMM form factor and requires a motherboard with DDR4 RDIMM slots that support ECC registered memory.

How does this 3200MHz CL22 module behave when installed alongside slower DDR4 RDIMMs in the same server?

The system will run all installed modules at the speed of the slowest module; this 3200MHz stick will downclock automatically to match the lower frequency.

How can I confirm this Supermicro certified module is running at 3200MHz with ECC active after installation?

Check the BIOS memory information or use a tool like dmidecode to verify the configured speed shows 3200MHz and the ECC status reports as enabled or active.
