Upgrading Processor

  1. There's nothing wrong with my PC. Working just fine eventhough I have been using it for more than 5 years now. I just want to upgrade the processor. Currently, I'm using AMD Athlon Thunderbird where FSB is 100. On the BIOS, shows FSB 100 selected. My MOBO support both FSB 100 and FSB 133.

    Few days ago, I got myself an AMD AthlonXP 1900+(Palomino). I've checked and it's supported by my MOBO. Except, the FSB is 133.

    When I installed the new CPU onto my MOBO :
    1. Monitor is blank
    2. Cannot access BIOS
    3. D-LED shows first 3 LED turn green and the last one is red

    My questions are :
    1. Proper steps on how to install new CPU that has different FSB from the previous CPU.
    2. Does BIOS auto-detect processor FSB
    3. What will happen to the CPU if different FSB configured on the BIOS.
    4. Any idea what when wrong beside "what you got there is a non-functional CPU"

    As an old hand with Socket A, I would ask you for the details of your motherboard. I suspect it does not support your intended CPU. BTW, I still have a working Athlon XP1800+ setup.

    Thanx for the info but I have the user manual when I bought the mobo but it doesn't help much. The questions remain...

    did you perform a bios update before putting in the new processor? You may need a bios update.
