RMClock utility (formerly known as AMD64CLK) is a simple utility designed for realtime CPU frequency monitoring and realtime adjustment of the CPU multiplier (FID) and voltage level (VID) of the upported CPUs via processor's power management model specific registers (MSRs). An AMD64 (AMD K8) family CPU supporting processor performance states transitions (known as AMD PowerNow!? or AMD Cool'n'Quiet? technology) is required. The presence of this feature is automatically detected at the program startup. New features in this version include:

Added CPU clock, load level and FID/VID monitoring graphs with text file logging feature. Added CPU load level determination on Intel Pentium II/III/M/4 family CPUs. Added throttled CPU clock determination for any forms of CPU clock throttling. Added support for multi-processor (SMP/HT) systems (for both monitoring and FID/VID management features). Added support for "mobile" and "server" (DBS) Enhanced Intel SpeedStep technology on Intel Pentium M and Xeon (Nocona) CPUs. Added CPU-specific power management related settings for AMD K7, AMD K8 and Intel Pentium M/Pentium 4/Xeon family CPUs (for advanced users only!). Added Minimal FID/VID determination and display (where available). Added CPU power management features presence and status display. Improved CPU/OS load measurement with load-averaging feature. Improved FID/VID control logic with CPU load level "noise filtering" (spike removal) feature.
