RightMark CPU Clock Utility (RMClock) is a small GUI application designed for real-time CPU frequency, throttling and load level monitoring and on-the-fly adjustment of the CPU performance level of the supported CPUs via processor's power management model-specific registers (MSRs). In automatic management mode it continuously monitors the CPU usage level and dynamically adjusts the CPU frequency, throttle and/or voltage level as needed. Features * Real-time CPU clock and CPU/OS load level determination and monitoring (with optional logging). * Detection of virtually any form of CPU clock throttling. * Dynamic on-demand CPU performance state (P-state) transitions via real-time adjustment of the CPU multiplier (FID) and requested voltage level (VID). * Dynamic on-demand CPU clock modulation via real-time transitions between CPU clock throttling levels. * Advanced CPU-specific power management settings for AMD K7, AMD K8 and Intel Pentium M/Pentium 4/Xeon CPU families. * Support for multi-processor (SMP/HT/multicore) systems. Supported CPU Current release of RMClock utility implements the CPU frequency, CPU load and throttling level determination on the following processor models: * AMD K7 (Athlon/XP/MP, Duron, Sempron) and K8 (Athlon 64/FX, Opteron 64, Sempron) family CPUs. * Intel Pentium II/Celeron, Pentium III/Celeron, Pentium M/Celeron M, Pentium 4/Celeron (Northwood and Prescott cores), Pentium 4 Extreme Edition (Gallatin and Prescott cores), Xeon (Prestonia, Nocona, Cranford and Irwindale cores), Pentium D and Pentium Extreme Edition (Smithfield core). Dynamic P-state transitions are supported on: * AMD Athlon 64/FX, mobile Athlon 64 featuring AMD Cool`n'Quiet technology. * Mobile or Low-Power Desktop AMD Athlon XP featuring AMD PowerNow! technology. * Intel Pentium M featuring Enhanced Intel SpeedStep (EIST) technology. * Intel Pentium 4 600 series (Prescott N0 core) and Intel Xeon (Nocona, Cranford and Irwindale cores), Intel Pentium D (Smithfield core) featuring Enhanced Intel SpeedStep (DBS) technology. Dynamic on-demand clock modulation adjustment is supported on: * Intel Pentium M/Celeron M, Intel Pentium 4/Celeron (all cores), Intel Xeon (all cores), Intel Pentium D/Pentium Extreme Edition featuring On-Demand Clock Modulation (ODCM). RMClock utility will run on unsupported CPU models, however, in this case, most of its functionality will be unavailable.
