    M2A-VM HDMI bad caps

    I got this motherboard for $2 (along with the $15 AMD X2 3500+ CPU). Previous owner said that it boots but freezes at the memory check. To my discovery there were bad caps... bad KZG nippon chemicon caps to be precise... all over the memory section of the board (not surprised here).
    Now... I haven't recapped boards in a long, long time... but I heard that solder is different now to what it was 5 years ago when I was still a kid and soldered boards for a living. It says RoHS on the board and I think this means trouble right? My ordinary Weller WTCPT solder iron isn't compatible or hot enough for RoHS is it?
    If I need a new iron, I'm scrapping the board!

    Add some 60/40 solder to the existing joints for better thermal transfer and I think you should be okay. If you have flux, that would help clean the joints too.

    My "sort by lowest price" ebay 40W made iron was able to recap 2 socket 775 boards (RoHS) with no problem.

      60 watts. should be fine

      wet the solder tips with 60/40 and some flux, then proceed to remove them by walking them out

        Yup, thanks for the help guys. I manage to desolder all of the 820uf 6.3v KZG caps which were swollen (and also the un-swollen ones too) and managed to find a bunch of 820uf 6.3V Panasonic FJ caps at the bottom of my cap collection. I must have desoldered them from another board a few years ago... but anyway, they are all on now and it's good to go. For a $2 motherboard, I can't say more!
