Cisco UCS C220 M7 DDR5 Kit

This 128GB kit contains eight 16GB DDR5 RDIMM modules built for the Cisco UCS C220 M7 rack server. Each module runs at 4800 MT/s with a CL40 latency and operates at 1.1V. The registered ECC design adds error correction and signal buffering for stable server operation.

IT teams running Cisco UCS C220 M7 platforms

Administrators who need validated ECC registered memory for this specific Cisco server will find the kit matches the required 288-pin DDR5 form factor and 1Rx8 rank structure. Buyers with consumer motherboards, laptops, or non-Cisco servers cannot use these registered DIMMs because the platform must support registered ECC DDR5.

Eight modules fill multiple DIMM slots

Installation follows the server manual slot population rules for the Cisco UCS C220 M7. The modules have no heat spreaders, so airflow across the DIMM area must be sufficient. Misplacing modules across channels or mixing with unbuffered DIMMs will prevent the system from posting.

Questions about this item

Will these DDR5 4800 CL40 1.1V ECC RDIMM modules work in my Cisco UCS C220 M7 server?

Yes, this kit is built specifically for the Cisco UCS C220 M7 and matches the required DDR5 4800, CL40, 1.1V, 288-pin ECC registered specification.

Can I mix these 1Rx8 modules with different rank memory already installed in the Cisco UCS C220 M7?

Mixing ranks is not recommended; for best stability populate all eight slots with these matched 1Rx8 modules as a complete 128GB kit.

How do I verify the kit is running at DDR5 4800 CL40 1.1V after installation in the Cisco UCS C220 M7?

Enter the BIOS or use Cisco UCS Manager to confirm the memory shows 4800 MT/s, CL40 latency, 1.1V voltage and all eight 16GB modules detected.
