64GB DDR4 3200 ECC Registered RDIMM

This single 64GB module uses 288-pin DDR4 technology rated at 3200 MT/s with CL22 latency and 1.2V operation. It is built as a 2Rx4 registered DIMM with ECC for error correction in server and workstation environments.

Suits Cisco UCS B200 M6 C125 M5 C220 M6 C240 M6

Designed for the listed Cisco UCS platforms that require registered ECC memory. It will not work in standard desktop computers and cannot be mixed with unbuffered or load-reduced ECC modules.

Check your Cisco UCS model and memory configuration

Verify the exact system model matches the supported list and confirm the motherboard accepts registered ECC RDIMMs. Ensure all installed DIMMs share the same capacity, speed and manufacturer for optimal stability.
