CPU-Z is a freeware system profiler (system monitor) application for Microsoft Windows (for all versions from 95 on) that detects the central processing unit, RAM, motherboard chipset, and other hardware features of a modern personal computer, and presents the information in one window. CPU-Z is more in-depth in some areas than the features that Windows XP provides to identify various hardware components, and is thus needed to identify certain components without opening the case, especially the core revision and RAM clock rate. »

gatotray is a tiny CPU monitor displaying several stats graphically (usage, temperature, frequency) in small space, and tight on resources.

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 on supported CPU models via processors 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, realizing the "Performance on Demand" concept. Notice: RMClock is different than CPU RM, those are two very different pieces of software designed to do different things. »

SysInfo Detector : This program to gather information of your computer configuration. It allows you to detect your hardware devices, their type, model, and other information, even if the system has no drivers. This is possible not only thanks to collecting of the information from the Windows registry, but also thanks to interrogating the devices directly in hardware.

AMD64 CPU Assistant monitors the temperature of AMD64 CPU cores (AMD64 K8 processor on Socket 754/S1/940/F1207/939/AM2/ASB1/S1g1) using the on-die thermal sensor.It also shows info about CPU and memory (load, timings, voltage, technical details) and includes a task manager.

Processor Hardware Control is a project to allow CPU voltage/frequency changing from userspace.

With Notebook Hardware Control you can easily control the hardware components of your Notebook.
