    Default ASRock N68C-S UCC crashing


    I have a ASRock N68C-S UCC mother board replaced in a HP Pavilion a6318f desktop puter. The machine was originally running Vista SP1 but crashed
    and burned and would not boot anymore. I replaced the drive (seagate 500GB SATA-II) and 2 new sticks of RAM (ddr2-533MHZ). The system is installed
    again, however it intermittently crashes on the following:

    [Hardware Error]: Machine Check Exception: 4 bank 1: b600000000000181

    Have to hard reboot the system to continue. The power supply I'm guessing may be too light for the new mother board/AMD cpu. Its the stock 250W one
    with the HP.

    Would this cause these exceptions?

    thx for any insight.

    Make sure that the RAM voltage and timings in the BIOS match the sticker on the modules.
    If not adjust them manually.

    I have that board with a Phenom II X2 555 Black Edition Callisto and 4GB (2x2GB) Kingston HyperX Blu DDR2.
    I use it as a test bench since it accepts AM2/AM3 and DDR2/DDR3.
    Right now it's powered by an Antec 480 True Blue but it has also run with a Dell 350W.

    You're right though; a 250w PSU might be pushing the limit.

    Installed new power supply - 350w and this seems to have done the trick. No panics in 2 days. So far so good.
