Cisco UCS C240 M7 memory kit
This 256GB kit contains two 128GB DDR5 4800 ECC RDIMM modules built for the Cisco UCS C240 M7 rack server. Registered buffering and on-die ECC protect data integrity in mission-critical workloads. The 4Rx4 organisation maximises density per DIMM slot. It is not for systems that require unbuffered UDIMMs or lower-density 2Rx8 modules.
Sustained load behaviour
Modules run at 1.1V with CL40 latency and PC5-38400 bandwidth under continuous server workloads. Samsung, Micron or Hynix DRAM is stress-tested at rated speed before shipping. Registered design reduces electrical load on the memory controller during extended operation. Buyers who need higher frequencies or lower latencies for specialised HPC tuning should look elsewhere.
Installation notes
The 288-pin DDR5 RDIMMs insert vertically into the server's DIMM slots following Cisco's population guide. No heat spreader is fitted, so airflow clearance matches the chassis design. Mis-seating a module or mixing ranks across channels is the most common cause of POST failures. Technicians without access to the Cisco UCS C240 M7 memory configuration guide should not attempt the upgrade.

Spørgsmål om denne vare
How much power does the 1.1 V DDR5 4800 kit draw under sustained load?
Each 128 GB module runs at 1.10 V DDR5 4800; total draw depends on the server's memory controller and workload, not on a fixed module rating.
What must the Cisco UCS C240 M7 already have to accept this 256 GB RDIMM kit?
The chassis needs free 288-pin DDR5 RDIMM slots that support 4Rx4 registered ECC modules at 4800 MT/s.
Will these CL40 4Rx4 modules run alongside different-rank DDR5 RDIMMs already installed?
The server's memory controller sets a common speed and timing; mixed-rank populations are supported if the platform's qualified-vendor list allows them.
