Cisco UCS C240 M7 DDR5 Kit

This 128GB kit contains two 64GB DDR5 4800 RDIMM modules built for the Cisco UCS C240 M7 rack server. Registered ECC design and 2Rx4 organisation target enterprise workloads that require data integrity and high capacity per slot.

DDR5 4800 Registered ECC Limits

The modules run at 4800 MT/s with CL40 latency and 1.1V operation under the PC5-38400 standard. Registered buffering adds a clock cycle for signal stability, so maximum throughput depends on the server memory controller and populated channel count.

Major OEM Chips 288-Pin Build

Samsung, Micron or Hynix ICs populate each stick without a heat spreader, relying on chassis airflow for cooling. The 288-pin RDIMM form factor fits only DDR5 RDIMM slots; desktop UDIMM or SO-DIMM boards will not accept these modules.

Questions about this item

Should I buy this 128GB kit or look for a different capacity for my Cisco UCS C240 M7?

This kit provides 128GB total using two 64GB modules, filling two slots with 2Rx4 registered ECC DDR5 rated at 4800 MT/s and CL40.

What does the 4800 speed rating actually deliver once installed in the server?

The modules run at DDR5 4800 (PC5 38400) with a CAS latency of 40 at 1.10V, giving the maximum standard throughput the Cisco UCS C240 M7 memory controller supports for this configuration.

Does the 288-pin RDIMM interface limit how fast the memory can run in this system?

The 288-pin DDR5 RDIMM form factor carries the registered ECC signals required by the server; the platform caps operation at 4800 MT/s, so the interface does not impose any lower ceiling.
