RMClock Utility
RMClock (formerly known as AMD64CLK) is a simple GUI utility designed for realtime CPU frequency monitoring and realtime 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 (reported by CPU itself) and adjusts the CPU frequency and/or voltage level as required
