Cisco UCS C240 M7 2TB DDR5 Kit

This 2TB memory kit contains sixteen 128GB DDR5 4800 RDIMM modules built for the Cisco UCS C240 M7 rack server. Each module operates at 1.1V with CL40 latency and 4Rx4 registered ECC architecture. The kit delivers 2TB of registered server memory in a single validated package. It installs directly into the 288-pin DDR5 slots of the target platform.

IT Teams Scaling Cisco UCS C240 M7 Capacity

Infrastructure teams expanding memory on a Cisco UCS C240 M7 will find the exact module count and specification the system requires. The 16-module kit fills all slots for maximum density in one purchase. Buyers needing smaller increments or non-ECC memory for other platforms should look at different configurations. This kit is tailored to a single server model and is not a general-purpose upgrade.

4Rx4 Registered ECC Determines Compatibility

The 4Rx4 registered ECC organisation is the specification that decides whether this kit works in the Cisco UCS C240 M7. The server memory controller requires this rank structure and error-correction mode for stable operation. A different rank count or unbuffered design will not function in this platform. Verify the system documentation calls for 4Rx4 registered ECC before ordering.

Questions about this item

How do I install the 288-pin DDR5 RDIMMs in the Cisco UCS C240 M7 and what step is often missed?

Power down the server, open the chassis, align each module with the slot key, press firmly until the ejector tabs click, then verify all 16 modules are recognised in BIOS before closing the case.

What maintenance or replacement will the 4Rx4 ECC registered modules need over time?

The modules have no moving parts or heat spreaders; only firmware updates or a failed DIMM would require action, and ECC corrects single-bit errors automatically.

What limit appears first when the 2 TB kit runs sustained workloads at 4800 MT/s and CL40?

The registered buffer and 1.1 V operation keep signal integrity stable, so the first bottleneck is typically the CPU memory controller's maximum supported capacity or channel count.
