    Nvidia 7600 AGP Card Caps

    Hi all- newbie first post, first recap here. Thanks for the message board, I've read through it a bit and learned a lot, I'm sure I will learn more with experience.

    I've got a couple of questions. 1st, I've got an old Nvidia AGP card with the (much revered) Sacon FZ series caps. 4 of the caps are toast (at least thats what I can tell visibly). Should I just replace all of them? My soldering skills aren't great and would like to try to get away with just replacing the blown ones. Also what would be a good cost efficient replacement? There are only 2 kinds, 10mm 1500uf 6.3v and 8mm 1000uf 6.3v. I was looking at these as replacements:

    Samxon Low ESR 1500uF 6.3v 10mm
    https://www.badcaps.net/store/produc...products_id=65
    and
    Samxon Low ESR 1000uF 6.3v 8mm
    https://www.badcaps.net/store/produc...products_id=70

    Any opinions? Thanks in advance!

    Re: Nvidia 7600 AGP Card Caps

    make the fz go away, those are by far the worst kind seen on mobos/graohic cards.

    replace all, those things literally EXPLODE!

    find a dead circuit board and practice soldering

    what iron/station are you using?

    some pics would be nice...

    and those caps should be fine. samxons are a good choice when money is a factor.

      Definately replace ALL sacon FZ, unless you want to pull the card out repair it again. the other caps are guarranteed to fail. They could already be bad, caps can fail without showing it. Sacon are Evercon, which are GSC, which are VERY unreliable.
      I love putting bad caps and flat batteries in fire and watching them explode!!

      No wonder it doesn't work! You installed the jumper wires backwards

        Thanks for the replies- here are some images of the offending caps.

        My iron is a Craftsman 45 watt, and I have 95/5 lead free solder. I got the lead free stuff because I didn't think handling lead solder and breathing it in would be good long term. I saw in a few posts though that others recommend 60/40 lead solder. Not sure it it matters.

          If the board was soldered with lead, use 63/37, 60/40 or 62/36/2 silver solder

          If its lead free, either remove all the lead free from the joint and use lead or use lead free.

          If it has ROHS mentioned anywhere, its lead free.

            Thanks for the tips all- caps are ordered and in the mail. I'll post (hopefully positive!) results in the next week or so.

              Its alive! I can't believe it- even with my *atrocious* soldering (big chucks of solder on the board) it powered up and ran perfectly on my first run. Wow! Now I did only replace the caps that were visibly blown. I wasn't confident enough in my soldering skills and did not want to try the others until i knew the ones I put on there worked. I have to decide whether I want to risk my bad (apparently good enough) soldering on the others now.

              By the way- it did have RoHS on it. I didn't think it would because its an older card. I used my lead free, large gauge solder that I have (that probably led to the big chunks). Anyway- just excited my first recap was a success. Thanks for the tips all. I may post a pic or 2 of the results as soon as I get a chance.

              Cheers,
              -Karl

                Nice work, good to hear it's working again!
                If you get a chance, though, do replace all of the FZ caps. Sooner or later they will all go bad and you would have to do this anyways. And don't worry about your soldering skills, I'm sure that won't do more damage than having Sacon FZ caps left on the video card.
                By the way, you should try regular 60/40 leaded solder. It would make your job a lot easier since it melts at lower temperature. If you're worried about the fumes, just work outside or open a window while working (but for one video card, I doubt if this matters at all).

                  Thanks for the advice. I'll swap out the FZ's and put in the good ones.

                    Just archiving everything related to bumpgate since most stuff has disappeared from Google. Maybe people will finally take the time to read some of it and stop shouting "reflow gpu" at every occasion but rather try to understand what the real issue is…
                    Interesting parts about the failure analysis are "Why Nvidia's chips are defective" and "Why Nvidia's duff chips are due to shoddy engineering"


                    May complete this post at a later date with more details.

                    EVGA e-GeForce 7600 GS AGP 256MD2 [256-A8-N542-T2] with bad caps - fixed
                    by momaka
                    I did it again – I had to fulfill my inner desire to fix yet another old piece of hardware. This one is actually kind of worthwhile, too – it’s an EVGA e-GeForce 7600 GS AGP video card, model P/N: 256-A8-N542-T2. With the popularity of “retro” PCs from the Win9x to XP era going up, and the diminishing supply of decent AGP cards, it is expected their prices will go up. Or is it? I bought the this video card rather on the cheap side (~$9 USD shipped to my door), because the eBay seller listed it for parts or repair (and correctly noted the bad capacitors.)

                    So, here is the...

                    Seasonic B12 BC-550 – barely 2 years old and with BAD CAPS already!
                    by momaka
                    I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.

                    For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

                    no-name Radeon 9600 XT recap and cooler
                    by momaka
                    I've been seeing a lot of cheap-looking (but not always so cheap) no-name AGP video cards on eBay for a while. They started popping up quite a bit when the market for AGP cards became more alive all of a sudden due to interest in “retro” PCs. One thing that struck me about these cheapo cards is that they almost always seem to come with garbage caps - including the abominable Sacon FZ. That aside, though, I've been wondering about the rest of the quality (or lack of?) on these cards. So I decided to satisfy my curiosity yet again.

                    This one was actually suggested to me by ChaosLegionnaire....
