A hardware optimization program that improves the machine by altering the chipset and the CPU. Found at www.powertweak.com, powertweak is an application that optimizes the chipset and the CPU. It acts like a driver for the CPU chipsets. It is used to both optimize the chipset, but it also unlocks several "hidden" features that can increase the speed of the system. It tweaks the internal registers of the chipset and processor that the BIOS for better communication performance between subsystems. Supported CPUs and chipsets can see a significant increase in I/O bandwidth, increasing the speed of the entire system. Currently the application supports most popular CPUs and chipsets, although you will need to check the website for your specific processor/chipset combo.
