    Core 2 Quad Q9300 will only run 1 core on Intel DQ45CB Board

    jwkoeberlein

      I just purchased a new Core 2 Quad Q9300 CPU for my dekstop which has an Intel DQ45CB motherboard in it. My issue is when I put in the new Core2Quad processor and I enabled the Core Multiplexing option in my Bios my pc will noot boot. I have the most recent Bios update for the DQ45CB(per the processor specs any Bios over 0059 should be fully compatible and im on 0129). If i disable the core multiplexing option, the pc boots fine but will only show the 2 boxes under Performance in Task manager for CPU Usage History so it will not run in "Quad" mode. Has anyone ran across this or have any ideas as to how I can get past this. My Core2Duo runs fine but I'd really like to utilize this new processor with that board! Any help or suggestions would be greatly appreciated.
