Cisco UCS C240 M7 memory kit

This 768GB kit contains twelve 64GB DDR5 RDIMMs built for the Cisco UCS C240 M7 rack server. ECC and registered buffering protect data integrity in enterprise workloads. The modules run at 4800 MT/s with a CAS latency of CL40.

DDR5 4800 registered DIMM limits

Registered DDR5 at 4800 MT/s tops out at the JEDEC standard voltage of 1.1V and the CL40 timing specified here. The 2Rx4 organisation and 288-pin interface fix the electrical load per channel. No higher speed or lower latency is guaranteed without platform qualification.

Twelve-module RDIMM kit for dense server configs

Twelve 288-pin RDIMMs fill all memory channels on the target platform for maximum capacity. The lack of heat spreaders keeps module height low for tight chassis spacing. ECC registration adds reliability for continuous operation in dense rack deployments.
