  • SpeedDDR5 4800 (PC5 38400)
  • ECCYes
  • Buffered/RegisteredRegistered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.10V
  • 1TB total capacity across eight 128GB modules
  • DDR5 4800 speed for high-throughput server workloads
  • ECC registered design detects and corrects data errors
  • 1V operating voltage reduces power draw per module
  • Validated for Cisco UCS C220 M7 rack servers

Capacity and Compatibility

This kit delivers 1TB of DDR5 memory across eight 128GB registered DIMMs. It is built specifically for the Cisco UCS C220 M7 rack server and operates at 4800MHz with CL40 latency. The modules run at 1.1V and include ECC error correction for data integrity.

Who This Suits

IT teams expanding memory in a Cisco UCS C220 M7 will find the 4Rx4 registered design matches the platform requirements. Administrators needing consumer DIMMs, non-ECC memory, or a different pin count should look at something else.

Sustained Load Behaviour

Each module uses major OEM DRAM from Samsung, Micron, or Hynix and is stress tested under load before shipping. The registered buffer and ECC circuitry maintain signal stability during continuous server workloads. The 1.1V operating voltage supports efficient long-duration operation.

Highlights

  • 1TB total capacity across eight 128GB modules
  • DDR5 4800 speed for high-throughput server workloads
  • ECC registered design detects and corrects data errors
  • 1V operating voltage reduces power draw per module
  • Validated for Cisco UCS C220 M7 rack servers

Questions about this item

Will this 8-module 1TB DDR5 4800 kit fill all memory slots in a Cisco UCS C220 M7 server?

The kit contains eight 128GB 288-pin DDR5 RDIMMs, matching the maximum DIMM count supported by the Cisco UCS C220 M7 platform.

Can I mix these 1.10V CL40 4Rx4 modules with lower-capacity RDIMMs already installed in the same server?

All installed DDR5 RDIMMs must share the same 1.10V operating voltage and registered ECC design; mixing different ranks or speeds may force the memory controller to run at the lowest common settings.

How do I confirm the server recognises the full 1TB at DDR5 4800 after installation?

Check the BIOS memory information screen or the Cisco IMC inventory; both should report 1TB total capacity, 4800 MT/s speed, ECC enabled, and all eight DIMMs present.
