The Max CPUID Value Limit in the system BIOS must be disabled for proper processor identification. Once processor identification is complete, the option can be re-enabled if desired.
To disable the Max CPUID Value Limit option, enter the BIOS setup screen while booting the system. For Intel® Desktop Boards, follow these steps:
- Press F2 while booting
- Select the "Advanced" tab
- Select "Boot Configuration"
- Set "Max CPUID Value Limit:" to "Disabled"
For motherboards from other board manufacturers, contact your system manufacturer for technical support information.
