Capacity 64GB

  • 64 GB capacity expands server memory for demanding workloads
  • DDR5 4800 PC5-38400 CL40 delivers high-speed registered performance
  • ECC registered design detects and corrects data errors automatically
  • 1 V operation reduces power draw in compatible Cisco UCS systems
  • Single 2Rx4 288-pin module fits C220 M7 SFF, C240 M7 SFF, X210c M7, X410c M7

Target System Memory

This 64 GB DDR5 registered DIMM is built for Cisco UCS C220 M7 SFF, C240 M7 SFF, X210c M7 and X410c M7 servers. It provides ECC error correction and registered signalling for workloads that require data integrity and high capacity in a single module.

Compatibility Check

Verify that the server model matches the listed Cisco UCS systems and that the memory slots accept 288-pin registered ECC RDIMMs. The module cannot be mixed with unbuffered or load-reduced memory and will not work in standard desktop platforms.

Sustained Load Behaviour

Operating at 1.1 V with CL40 latency at 4800 MT/s, the module maintains JEDEC-spec timing during continuous operation. Registered buffering and ECC correction keep signal integrity stable across all 2Rx4 ranks under extended server workloads.
