768GB DDR5 4800 server kit

This 768GB kit contains twelve 64GB DDR5 4800 ECC registered DIMMs built for the Cisco UCS C220 M7 rack server. Each module runs at 1.1V with a CAS latency of CL40 and a 2Rx4 organisation. The registered design adds a buffer that stabilises the memory bus in high-density configurations.

Sustained load stability

All modules are stress tested under load before shipping to verify reliability during continuous operation. Error-correcting code detects and corrects single-bit errors on the fly, preventing data corruption in long-running workloads. Registered buffering reduces electrical load on the memory controller when every slot is populated.

Twelve-slot registered layout

The 288-pin DDR5 RDIMM form factor fits the server's twelve DIMM slots without a heat spreader, allowing tight spacing in the chassis. Major OEM chips from Samsung, Micron or Hynix are used depending on supply. No desktop or consumer board can accept this registered ECC configuration.

Questions about this item

How much power do the 1.1 V DDR5 4800 modules draw when the Cisco UCS C220 M7 runs continuously?

Each module operates at 1.1 V DDR5 standard voltage; total system draw depends on the server workload and the 12 x 64 GB population.

What must the Cisco UCS C220 M7 already have to accept this 12 x 64 GB registered ECC kit?

The server needs 12 free 288-pin DDR5 RDIMM slots and a BIOS that supports 2Rx4 registered ECC modules at 4800 MT/s.

Will these CL40 2Rx4 modules run alongside any older DDR5 DIMMs I might keep in the same chassis?

Mixing ranks or speeds is not recommended; the kit is validated as a matched 12 x 64 GB set for the Cisco UCS C220 M7.
