Capacity and form factor

This 384GB kit contains six 64GB DDR5 modules in the 288-pin RDIMM form factor. Each module operates at 4800 MT/s with a CAS latency of CL40 and runs at 1.1V. The memory is registered and provides ECC protection for data integrity.

Server administrators and unsupported platforms

IT teams managing Cisco UCS X410c M7 compute nodes can deploy this kit to reach the full 384GB capacity across six slots. Systems that require unbuffered UDIMM modules, non-ECC memory, or a different pin count cannot use these registered DIMMs. Builders needing lower capacities or consumer desktop memory should select a different product.

Registered ECC RDIMM requirement

The single specification that decides fitment is the registered ECC RDIMM interface. Only motherboards and server platforms designed for 288-pin DDR5 RDIMMs with 2Rx4 organisation will accept this kit. Verify that the target system explicitly supports registered ECC DDR5 before purchase.

Questions about this item

Should I choose the 6×64 GB kit or a different capacity for the Cisco UCS X410c M7?

The kit provides 384 GB total across six 64 GB modules, matching the node's six-channel architecture for full bandwidth.

What does the 4800 MT/s rating deliver inside the Cisco UCS X410c M7?

The modules run at DDR5 4800 with CL40 latency at 1.1 V, giving the compute node its maximum supported memory throughput.

How does the 288-pin DDR5 RDIMM interface limit performance in this server?

The registered 288-pin DDR5 interface caps the kit at 4800 MT/s and CL40, which is the platform's native ceiling for 2Rx4 ECC modules.
