    my MSI passive GF 7600GT

    Hello guys,

    Yesterday I received my MSI GeForce 7600GT with passive cooling (NX7600GT-T2D256EZ) and started investigating the capacitors used on it. I don't know much about the subject, all I know is that some types are considered bad and can cause problems. Unfortunately, my MSI card has a few of them.

    Here is the list of caps used on this card, along with their markings:
    • 2x Fujitsu (I guess..it's yellow and has an F on it)
      -55°C - +105°C
      16V 330uF
      M
      6261u
    • 5x Panasonic (it has the Matsushita logo)
      +105°C FJ
      1000uF
      6.3V
    • 2x Sanyo
      SO.CON
      G
      SP
      105°C 7B
      680
      6.3
    • 1x Nichicon
      680uF 16V
      105°C
      H0524
      HM(M)


    If I understand correctly, the Nichicon and Fujitsu are troublemakers. Now, I don't know what to do..I'm afraid to use the card. I still have 6 days to get my money back or switch it for another card. If I were to switch, I would try an ASUS passive GF 7600GT. But, of course, I'm not sure if I will be better of with that one as no info is widely available on the caps used on these things.

    I was wondering if you guys could give me some advice. I also bought an MSI K9N SLI Platinum with it, it also has some problematic caps. I'll make another thread about it later on as I don't have the time atm. Would appreciate it if you could visit it as well.

    Thanks in advance!

    fujitsu fail rarely i wouldnt worry about that. i have them in various items and no probs.
    the bad nichicons were from 2003 not 2005 as on your card

    i am optimistic your card will be fine. i do comment however that it is dissapointing to see lack of expensive caps like chemicon psa or psc, oscon svp or sepc on a card from that price range. they cheaped out a bit on the FJ and HM.

      Thanks for the reply! This puts me a bit at ease.

      Although wikipedia states
      Nichicon HM / HN series capacitors found on an ASUS p4p800-se motherboard (12-4-2006)
      as bad caps.

      I don't plan to overclock, but if I were to..would this increase the risk of caps going bad?

      I'll examine the motherboard in more detail this afternoon and post a thread for it in the appropriate forum.

        well i can only refer to the few actual date codes i have for nichicon fails. basically it is not guaranteed that a brand new manufactured cap will be installed on a board. So if we consider that with the about 18 month time for those nichicon fails for that p4p800-se to fail 04/2006 it would have been installed around 12/2004. Then the caps would have been manufactured some time before that, might have been a year or more. anyway its certainly not an exact science, we might have another wave of nichicon fails in the future but at the moment there is not indication of that.

        I saw intel was confident enough to use HM series on their newer boards. but regarding it being alleged that the bad ones were a bad batch, the HN at least was seen to be a batch which was produced accross several weeks. HM series from older boards of a few years back are still ok today.

        i doubt if overclocking would affect the caps. its another grey area. might as well overclock it though, rivatuner is a nice software if you have onboard temperature monitoring, cos you can test the settings and log the temps before you use it in serious gaming. depends on the card series though what you can do with it. i dont overclock my cpus at present but i like overclocking my gpus.

          I see! I was wondering how you know the HM on my card is from 2005? Is H0524 some sort of "date code"?

          Then about those Panasonic FJs, are you saying that even between Panasonic's own caps there is a quality difference? There are lots of them (FJ) on my motherboard.

            0524 = 2005 week 24

            FJ are produced by panasonic malaysia. I have never seen specs on them but they appear to be for asian market only, perhaps they are the same spec as FM or superior.

            no what i was saying was FJ and HM whilst they are quality caps they are wet electrolytics rather than the superior and more expensive polymers capacitors seen on many graphics cards. polymer caps do not have liquid electrolyte therefore they do not have the same failure characteristics as caps with liquid electrolyte. they also have far superior specifications.

            i wouldnt worry about it.

              the purple coloured oscon SP series you have on your card is a polymer cap. That series is useful because it is available in larger capacitance and voltage than the polymer series SEPC (very low esr) and SVP from the same manufacturer.

              read some spec sheets here to understand the caps.
              https://www.badcaps.net/forum/showthread.php?t=613

              basically it is

              lower esr is best
              higher ripple is best
              endurance (well it is your choice for the application. dont forget that 2000hours for instance is not 2000 running hours at room temperature, it is 2000 hours at 105oC. when the temperature the cap is working at is lowered the longer the actual endurance will be)

                Okay I won't.

                edit: Well I must say, I'm not really into all of these technical details..but I'm developing a slight interest for it. I have a couple of books on the subject lying around, so I might grab them and start reading. Thanks for the info!

                  you should learn to recap then you wont worry again.

                    yea, there are no fear for they who can recap (quoted somewhere)
                    days are so short when you actually do something..

                      Hi TomMe,

                      I'm afraid my reply hasn't much to do with caps or almost.

                      It's about the passive cooling and temperatures that are attained under full load. What temperatures do you get when gaming etc ? I can't find any articles or tests about this passive version, only the active cooled version. The article below states a XFX 7600 GS (Lite GT), going up to 103°C under load, which is really frigging hot. So I wonder what a passive cooled 7600GT will do. In the future I would like to add a second card to go SLI, so you can figure why I'm concerned

                      It would be great if you could let me know how your MSI NX7600GT-T2D256EZ is doing.

                      Thx
