CrystalCPUID is a CPU-diagnostics program. It helps to determine the types and properties of the processor(s) used in the system, as well as the actual clock rate. In case of certain CPU types it also offers some setting options. These all fall under the tuning category – manufacturers do not support this, so you can use this function only at your own risk.
Most important features:
- AMD64/EM64T support
- Intel SpeedStep Control (At your own risk!)
- Modifying AMD K6/K7/K8 multiplier and voltage (At your own risk!)
