RightMark CPU Clock Utility (RMClock) is a GUI application designed for realtime CPU frequency/load monitoring and on-the-fly adjustment of the CPU multiplier (FID) and voltage level (VID) of the supported CPUs via processor's power management model specific registers (MSRs). In auto-management mode it continuously monitors the CPU usage level and dynamically adjusts the CPU frequency and/or voltage level as needed.
- Realtime CPU clock and CPU/OS load level monitoring (with logging).
- Detection of virtually any form of CPU clock throttling.
- Dynamic CPU performance state transitions (realtime adjustment of CPU multiplier, FID, and voltage level, VID) "on demand" on supported CPU models.
- Advanced CPU-specific power management settings for AMD K7/K8 and Intel Pentium M/Pentium 4/Xeon CPU families.
Support for multi-processor (SMP/HT) systems.
