The 1usmus Custom Power Plan represents a specialized power management solution created specifically for AMD’s Ryzen 3000 series processors based on the “Zen 2” architecture. This utility was developed and released by the creator behind the DRAM Ryzen calculator tool, who is recognized in the Guru3D community as Yuri “1usmus” Bubliy.
This custom power profile has undergone testing with AMD’s high-end processors, particularly the Ryzen 9 3900X and 3950X models. The primary purpose of this power plan is to address and optimize CPU clock speed behavior issues. It demonstrates particularly effective performance with the 3900X processor, enabling it to achieve peak boost frequencies while maintaining lower operating temperatures during idle states or when processing tasks on single cores.
