What is C1E and how do i get it

Hello,
i just upgraded from a 2.8 celeron to 3.0 pentium R cpu. running xpsp3.
when the system boots it halts and shows " cpu overclock error and indicates that it supports C1E Bios"
my motherboard is P4M890-M7 SE
i normally just restore everything to defaults and disable boot floppy.
is there any other setting i need to adjust?

More about what
  1. Are you using the latest BIOS version for your motherboard?

    Did you use the JCMOS1: Clear CMOS Header to restore the BIOS Settings to the default safe settings?

    What is your Phoenix - AwardBIOS CMOS Setup Utility --> Advanced BIOS Features --> CPU Feature --> C1E Function setting set to [Auto] (default) or [Disabled]?

    What is the make and model of your memory modules? Are the memory modules running at the correct speed, timings and voltage.
  2. Sounds to me like the BIOS does not recognize your CPU, does it display the name of the CPU accurately at the start of POST?

    quite correct.it doesn't show cpu info post bootup.
    i have checked system property and even run dxdiag
    its still void.

    is it possible that the previous celeron 2.8 was better than the current cpu intel R 3.0?
  6. Is your CPU one of the ten 3.0 GHz Pentium 4/D CPUs listed in the BIOSTAR P4M890-M7 SE Ver. 7.x CPU Support List?

    That would confirm that your BIOS revision is too old for the CPU you have installed and support for it is not built in yet, or if you have the latest BIOS available already, the board simply may not support your new CPU. I would check for a BIOS update first though.
