Capacity and purpose

This kit provides 128 GB of DDR5 registered ECC memory in eight 16 GB modules. It is built for the Cisco UCS X410c M7 compute node and suited for virtualisation hosts or database servers that need maximum capacity per channel.

DDR5 4800 registered limits

The modules run at 4800 MT/s with CL40 latency at 1.10 V. Registered buffering adds one cycle of command delay and the single-rank 1Rx8 organisation caps density per DIMM, so very large configurations may not reach the platform’s theoretical maximum bandwidth.

Installation notes

Insert the 288-pin RDIMMs into the node’s memory slots following the population order in the Cisco service guide. The most common issue is mixing registered and unbuffered DIMMs or populating slots in the wrong sequence, which prevents the system from posting.

Questions about this item

Should I pick the 8x16GB kit or a different capacity for my Cisco UCS X410c M7?

The kit supplies 128GB total across eight 16GB modules, matching the node's eight memory slots for full population and maximum bandwidth.

What does the 4800 speed rating mean once installed in the Cisco UCS X410c M7?

The modules run at DDR5 4800 MT/s (PC5-38400) with CL40 latency, delivering the rated throughput the compute node's memory controller supports.

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

The 288-pin DDR5 RDIMM form factor carries the 4800 MT/s signal; the Cisco UCS X410c M7 memory controller caps operation at that speed.
