  1. I have...

    Win XP Pro DX 9.0c (not SP1)
    Asus K8V SE Deluxe
    MSI FX 5900ZT 128MB
    Corsair Value Select 2x256mm DIMS @ DDR 400mhz CAS 3.0ns
    In my BIOS when I go to my "JumperFree" (wtf?) options menue, it allows me to adjust the voltage to my hardwares and also allows me to change my CPU's speed and FSB.

    I'f i'm not mistaken, my CPU has an FSB of 800mhz yet I can only set it to a maximum of 300mhz ????

    Whats even worse is that when I do set it to 300mhz, my system fails to boot and I must go back and re-set it to the default 200mhz :mad:

    Whats going on here?

    Is it a memory threshold or something?

    Hope you guys can help cos I rea;;y wann play my games at 800mhz FSB. Extra frames :bounce:

    Some motherboards require that your memory speed be equal to the FSB speed. However, I've only seen that on AMD based motherboards. Try reading your motherboard instruction manual or e-mail the company. Good Luck!

    First of all the Athlon64 does ntot even have an FSB. It is connected to the rest of the rest of the system through HyperTransport link.
    In the BIOS, your HyperTransport link needs to be set to 200. Anything above that is overclocking.
