QPI frequency

Updated: 11/13/2018 by Computer Hope

Short for QuickPath Interconnect, the QPI frequency or QPI Clock is a technology designed to replace the FSB (Front-Side Bus) on a computer motherboard. Intel developed it to compete with HyperTransport. The basic QPI connects one or more processors to one or more I/O (input/output) hubs, allowing all the components in the computer to communicate with each other over the network. The initial release of QPI frequency can transfer 25.6 GB/s with a theoretical bandwidth of 1600 MHz.

Computer users interested in overclocking their computer may see an option like the example picture below in the CMOS setup that enables them to adjust their QPI frequency. We recommend leaving this setting at Auto or the default settings. Adjusting this setting to make the computer faster makes no noticeable difference.
