The PCG marking on the processor and processor box is used by Intel and third party board and component vendors as a common method to describe processor power requirements. PCG does not promise compatibility, but is an indication of processor electrical requirements. In addition to PCG requirements, processors have board support requirements such as chipset, BIOS, and pin considerations that can determine processor-board compatibility. Intel recommends that you contact your motherboard manufacturer to obtain a supported processor list when selecting a processor for your motherboard.
