NEMIX RAM 192GB (6x32GB) DDR5 4800 CL40 1.1V ECC RDIMM Cisco UCS C220 M7 memory upgrade

Cisco UCS C220 M7 DDR5 upgrade

This 192GB kit contains six 32GB DDR5 ECC registered DIMMs built for the Cisco UCS C220 M7 rack server. Each module runs at 4800MHz with a CAS latency of 40 at 1.1V. The registered design adds signal buffering for stable operation in multi-slot server configurations. It targets administrators expanding memory capacity in this specific platform.

PC5-38400 1Rx4 registered ECC specification

The modules conform to the PC5-38400 standard with a 1Rx4 organisation and 288-pin DDR5 RDIMM form factor. ECC and registered buffering are mandatory for the Cisco UCS C220 M7 memory subsystem; non-ECC or unbuffered DIMMs will not function. Buyers needing consumer desktop memory or unregistered modules should select a different product line.

1.1V operation without heat spreaders

The kit operates at the standard DDR5 server voltage of 1.1V and ships without heat spreaders, relying on the server's directed airflow for cooling. Power draw scales with the six-module population and 4800MHz data rate, so adequate chassis airflow is required. Systems lacking sufficient air movement or expecting passive cooling should not use this configuration.
