This 128 GB DDR5 registered DIMM runs at 6400 MHz with CL52 latency. The 2Rx4 organisation uses 32 Gbit density chips in a single module. It is built for workstations and servers that require registered memory.

Thermals and power in normal use

Registered DDR5 modules include an on-die power management IC that regulates voltage locally. Typical operation stays within standard DDR5 thermal limits without additional cooling. Power draw scales with the 6400 MHz data rate and 128 GB capacity.
