    Is that an old Gigabyte motherboard? If so, then from what I've read around here I think the accepted answer is "yes".

    But in the general case, the answer would be "no".

      Depends on what voltage it's on.
      If you use 6.3v caps then the voltage they are on [+ ripple voltage] must be less than 6.3v.

        Yup, its Gigabyte old motherboard GA-8IDML. support socket 478 and Sdram.
        Its 3 * 3300 choyo vrm capacitor is bulged and i am planning to recap it and other badcaps too. Weird thing is Gigabyte use Sanyo OS-CON and Panasonic FJ capacitor parallel with the Choyo caps at VRM secondary side, I wonder why their engineers do so...

          Thanks for comments, I think i will testing the voltage on it by multimeters

            OS-CON + FJ + Choyo in the same VRM is indeed strange.

              If the voltage tests out, then I think you can use the 1000uF 6.3v caps. Haven't done it myself but many people here have posted about making that sub and it seems to work fine for them.
              In general you wouldn't want to boost the capacitance that much though.

                These are 3300uF Choyo not 330uF.
                I would stick with 3300uF caps.
