GCPUID

GCPUID is a minimal software solution that displays information about your CPU, relying on a very user friendly and easy to browse interface.

All features are grouped in the main window, so you can easily check out CPU, feature flags, cache, system and PCI devices information just by clicking on the available buttons.

The CPU screen shows not only general processor details, such as vendor, processor and instructions, but also bus speed and CPUID information. Plus, if you use a multi-core processor you can access details for every single core.

The feature flags and the cache windows come with quite self-explanatory names, so it's pretty easy to use them all, without even asking for assistance.

While the system tab shows the operating system, version, build and system memory, the “Power Management” window available under the “Extras” menu is much more important.

While it shows the current, maximum and minimum multipliers, it also lets you set a new multiplier. Plus, it displays current, maximum and minimum voltage, with a separate option to set a new voltage. Obviously, pay attention to these options, as they may cause serious damage to your computer.

GCPUID works fine on all Windows versions, but administrator privileges are required when launching it on Windows 7.

Overall, GCPUID does what it says and doesn't hamper system performance at all. Truth is, it is not addressed to beginners, but a more detailed help manual would come in handy, especially since it boasts options that could damage the system.
