Cisco UCS C240 M7 memory kit

This 256GB kit contains eight 32GB DDR5 RDIMM modules built for the Cisco UCS C240 M7 rack server. Each module is registered and ECC-enabled to maintain data integrity under continuous enterprise workloads. The kit arrives new and ready for installation in compatible memory slots.

DDR5 4800 registered ECC limits

Registered DDR5 at 4800 MT/s with CL40 latency operates at the JEDEC base speed for this generation. The registered buffer adds one clock cycle of address-command delay, which stabilises large populations but caps peak throughput compared to unbuffered alternatives. ECC overhead consumes a portion of raw bandwidth for error correction.

256GB capacity and headroom

Eight ranks of 1Rx4 DRAM deliver 256GB total capacity, allowing large virtualisation clusters or in-memory databases to scale within a single chassis. The 1.1V operating voltage reduces power draw per gigabyte, yet the fixed eight-module population leaves no free slots for further expansion without replacing the kit.

Preguntas sobre este artículo

Should I pick the 256GB kit or a smaller capacity for my Cisco UCS C240 M7?

This kit provides 256GB across eight 32GB modules, filling eight DIMM slots for maximum supported capacity in the Cisco UCS C240 M7.

What does the 4800 speed rating deliver in this server?

The modules run at DDR5 4800 (PC5-38400) with CL40 latency, giving the rated bandwidth and timing the Cisco platform expects for stable operation.

Is the 288-pin RDIMM interface the right fit for my Cisco UCS C240 M7?

Yes, these are 288-pin DDR5 RDIMM registered ECC modules at 1.1V, matching the Cisco UCS C240 M7 memory slot and voltage requirements.
