    Hey Guys,

    I'm building a server (Athlon 900 in an HP K7M board) with a ton of IDE storage.

    I found some silk-screens on the mainboard for HARDWARE overclocking (NO BIOS OPTIONS)

    [​IMG]

    I have so many questions...where to start...

    OK, the board has no headers in the areas designated by the picture. It DOES have through hole solder pads. I am good enuf with an iron to put some headers in there....
    The question is - Do you think the traces have been cut to prevent overclocking?

    The DSW(1) and DSW(2) appear to be right next to that silkscreen (with a resistor in the middle).
    Is the rightmost solder pads DSW(2)?

    I measure 0 volts on all (apparent) DSW pads, as well as the left lead on the two resistors.
    The right side of the resistors measures 1.721V. Whats the signifcance?
    How should I jumper the DSW to get a higher FSB?
    Should I put headers in the solder pads and use PC jumpers?
    I don't know if it will do anything as all solder pads measure 0V.
    Also the silkscreen says ON and OFF. With default as both ON. I was thinking I might have to cut a trace or jumper the 1.721V side of the resistor into on of the headers. Thoughts?

    As for CPU voltage, that shouldn't be too difficult. The 4 pad headers are there, and some measure to 5V (ON) and some measure to 0V (OFF). The question here is:
    Do you think its hard-wired (or traces been cut) to prevent using the CPU voltage adjustments? The silkscreen says the jumpers are at 3-4, 3-4, 3-4, but there are NO headers and NO jumpers (or solder bridges).

    Any insight gets +1 :)

    thanks

    OK I figured out the VID's, there are 0 Ohms jumpers I can remove to set the Vcore.

    The DSW is confusing me. The empty header labeled DSW1, the solder points where the pins go are shorted together (0 Ohm). They don't appear to have traces either. It looks like the ports are simply tied to the ground plane in the PCB.

    Any ideas? Raising CPU voltage does not good unless I can up the FSB :wtf:

    help please :laugh:

    Thanks

    Well, the motherboard will not allow overclocking. The FSB is set in the hex part of the bios to 100 and cannot be changed...

    Pulled the cover to the Althlon 900 and found the cpu is rated for 950 :confused:

    Found some pin mod guides and such. bumped the multi up a half step by moving around some resistors and BAM boots at 950 mhz W00t

    No thanks to you guys :wtf:

    :roll:j/k
