    Don't Upgrade - Overclock!

    Upgrading your PC with a new CPU isn’t always necessary - if you can overclock the processor to meet the specification of your choice of replacement processor, you might opt to stick with the one you already have.

    If you’re planning on overclocking your processor, you need to make sure you have the right tools for the job. Downloading just any freeware overclocking utility isn’t necessarily going to give you the best results – the one you choose might be designed specifically for one motherboard, processor brand or even be outdated.

    Below is a selection of top overclocking freeware that you might want to try.

    CPU-Z 1.53

    CPU-Z is a vital system management and overclocking freeware tool One of my favourite tools, CPU-Z is a vital addition to the arsenal of any overclocker, regardless of whether they use Windows-based tweaking or make their changes to the system clock in the BIOS.

    CPU-Z won’t overclock your PC, but provides a range of information that you can use to identify how overclocking will affect your system, by collecting vital information about your PC system such as your processor type, memory type and motherboard specs. While other overclocking tools might supply some of this information, they rarely include it all.
