  1. I have just put together

    gigabyte ma770-ud3 motherboard
    AMD phenom II x3 720
    4gb ram ddr2 800
    HIS Radeon HD4650 1gb
    32bit XP

    When i first got everything going the processor showed up as what it is. I started messing around with some of the bios and overclocking. The computer wouldnt load so I changed everything back to default. Everything works fine, i ran a
    performance test and it test fine, i just don;t know why it would show only 787mhz. Does it even matter? I also have 4gb of ram installed and its only showing 3.25? Any help would be great thanks.

    Only 3.25 gigabytes of ram show up because you have a 32 bit version of windows. As for the CPU speed, have you reset the CMOS? Also, try using CPU-Z to check your CPU's speed.

    using the cpu-z it says the core speed is 800mhz, do i need to change that in the bios or something?

    It could be that the cpu speed is only 800 mhz because of a power saving feature. Put your cpu under load, by using Prime95 or something similar, and see what the speed goes to. For reference the CPU's multiplier should be 14 under load, and the bus speed 200 mhz.
  5. Go into your bios and disable cool n quiet or go to windows power options and change it to performance.
