It is the screenshot of my CPU clock when running Folding@home v7.2.9.
What is Folding@home?
It is a program running on home computer, working on a the protein folding project. All the computer participated work on one project, and share the work load.
More details to Stanford University project site.
The CPU is AMD A8-3870K. It has integrated DX11-class Radeon HD 6550D GPU core. CPU is 4 cores. Default 3000MHz core speed.
Actually, before I run Folding@home on this desktop, I seldom see the clock or CPU frequencies reaching 3000MHz. Most of time it is only 780MHz.
