Processor is not identified correctly by the operating system or an application

Important Note: Disassembling, assembling, upgrading and troubleshooting computers should be performed only by a computer professional since the electronic devices may cause serious damage to the installer, the system and its components if it is done improperly. Before attempt to disassemble or assemble laptop computers, carefully review the documentation specific for the laptop computer and its related components. Make sure that you will not be voiding the warranty of the system by opening the laptop computer or replacing any of the components in the laptop computer. Lastly, make sure to follow Electrostatic Discharge (ESD) procedures.

  • You should make sure that the laptop computer supports the processor that you are installing including type of processor, speed and voltage.
  • Check if there are any jumpers or dip switches that need to be configured on the laptop computer including those that indicate the speed of the processor.
  • Check the CMOS setup program for processors settings.
  • Update to the newest BIOS version.
  • Run the Intel® Processor Frequency ID Utility to verify the processor.
  • Since many programs detect the processor so that they can better utilize their features, the software may have been written before the processor existed. Therefore, check with the software manufacturer for a patch.

    Note: If an application cannot identify a processor, the software will not run with the processor or it will assume it is an older processor without many of the features that the processor offers resulting in slower performance.
