  1. Hello all i'm new to the forum and would like to say hello to all
    I need help with two problems
    The first is this: The post reporter continualy repeats over and over again cpu failure and theres nothing wrong with the cpu.I have disabled it in bios but she won't stop also iv'e tried to delete it in winbond but it continues
    Can anyone tell me how to get rid of it?

    Question two the system was set to 200 fsb with a multiple of 11 but the bios has reverted to 100fsb if i change it to what it was ie 200 it won't boot The board has been working flawlessly for over two years.The only thing i changed is i removed one stick of ram to put in another board could that be the cause

    cpu amd 2500 barton

    twinmos 512mb pc 3200 ram
    If you need more info just ask

    How is the post reporter telling? Beeps? How many and short/long?

    Swap the ram you took out with the ram you left in - I'd bet on a bad module.

    From what I can discern the stock setting for that cpu in bios is 166 with a multiplier of 11. People running the unlocked versions higher than 166 also had to adjust core voltages.

    I may be wrong - I am not an overclocker (not even an overachiever).

    the a7n8x deluxe rev 2.00 has 200 mhz fsb support x 2 the board has been set this way from new and i have never changed core voltages

    LOL - I was researching the -E version; in any case, pull the cmos battery or use the cmos jumper to reset it and try again.

    The site:

    has a post by 'Paul' that includes, in part, "

    "No CPU installed" message is from a hard wired signal.

    "System failed CPU test" and "System failed memory test"
    use the timer inside the Winbond chip. The rest of the
    messages in the table, can only be triggered by the
    system processor writing the appropriate event code
    into the Winbond chip.

    If the BIOS setting is disabled, it is easy to see that
    everything except the three cases above will be disabled.
    What I don't see, is how the "No CPU installed" message
    can be stopped, as the signal just comes from the CPU
    socket and goes to the Winbond chip."
