    Old GA-7VT600 missing caps

    Found this forum just a week back and it`s awesome, lots of useful stuff here and the community is just outstanding. Thanks for existing!

    I got a Gigabyte GA-7VT600 MB, salvaged from recycle bin, because I thought it was faulty.

    One day I decided to test it once again and to my surprise it worked well at first glance. I`ve installed an OS, drivers and even some games. But then for unknown reason I removed it from the case to discover that it has about 4 caps(EC31,EC33,EC36,EC38) missing (didn`t noticed this when putting it in). I must admit that I didn`t stress test it, but it seems to work just fine.

    So here are my questions to you guys:
    1. How is it possible to work fine under those circumstances? You can see that those caps missing are around CPU.
    2. What caps are needed since I believe that it won`t last long before it dies without those caps?
    3. The only problem I encountered when installing drivers was that there was no sound was coming from speaker out hole (green one) but oddly enough the driver "sense" when a jack is plugged in. If set to emulated 5.1 speakers, there is still no sound on the green hole, but the blue one (line out) which acts as the back speakers has. Could the missing caps cause this problem too ?

    On another note, I suspect that there are another two caps missing(see pic #2, rectangle shape) but I can`t be sure since there is no resin left like the other 4.

    Any feedback will be appreciated, guys! Thanks!

    Re: Old GA-7VT600 missing caps

    See this: https://www.badcaps.net/forum/showthread.php?t=11645

    See the original mb picture, with caps missing by default: http://www.gigabyte.com/fileupload/p...2/1666/301.jpg
    This article shows more pics with the caps missing by default: http://www.neoseeker.com/Articles/Ha...-7VT600/3.html

    You can get a clue about the values from this article - zoom the picture and do a negative or something: http://www.pcstats.com/articleview.cfm?articleID=1597
    I can read from that OST RLX 105C and on the left there's 2300uF (or 2200/3300?) 6.3v and the ones on the right are about the same height and diameter, so if i were to guess i'd say the same values.

    This article for the -L variant which should be about the same in the cpu area ( http://www.mbreview.com/mbr-reviews/...l.html?start=2 ) says 3300uF near the heatsink:

      Those are all 3300Uf 6.3v 105C caps. You probably used them to repair another board.

        Thanks for the info mariushm, I`ll have to do some research!

        @Spitz Yes, probably the caps were used on another mb but I didn`t remove them. That`s why I asked in the first place.

        Still, can`t explain how can it work with 4 caps missing...

          luck

          I have that same motherboard in my hands right now, I got it working but later it stopped. I did replace one cap with a ruby, and actually took one off for another board. I'm thinking the KZG's next to the northbridge to to blame here

          those are 6.3 3300

            that is what I was looking for, Uranium.

            I had a feeling that 3300uF @6.3V are needed and now I`m sure.

            Sadly, at the moment I only have KZG caps salvaged from another mobo.

            Thanks all for replies!

              Missing caps are not uncommon.
              They sometimes build multiple models or versions on the same PCB.

              Looks like you may have Nichicon HM too.
              Those were defective from 2001-2004.
              [ H0322 = year 2003, week 22 ]

              In most cases the basic plan for a reliable board:
              - For 6mm and up diameter caps.
              Replace all non-jap brands.
              Replace any Chemicon KZG & KZJ.
              Replace any Nichicon HM & HN with date codes 2001-2004.
              -
              Other things come up but that plan works for most boards.
              .
              This should help some:

                PCBONEZ-did you look at all the pictures? flux in place of missing caps pretty much indicates they were taken out

                come to think of it, not having those caps might burn your vrm/cpu, so that might be why its

                those questionable ones without flux and have soft solder do have one cap, but one shows as a blank spot with no cap

                EC32 is another 3300 6.3. EC37/EC34 have no caps. EC2 (in the same line) has a 6.3 1500.

                dont' run this motherboard without replacing these caps, it might work right now, but eventually kill your power regs

                I replaced the KGZ's with rubys, and the 3300's with pannys, still does not post. this board is dead.

                  No I didn't look at the flip-side pic so I didn't notice.
                  2x on Vcore did sound way too few though.

                  I agree, don't run it -at all- until those caps are replaced.

                    Re: Old GA-7VT600 missing caps

                    Well, it`s job done. Thanks for the photos and info provided by you guys.

                    In total, I`ve put 5 caps, some crappy one, but it`ll do.

                    I guess 6 hours with prime95 makes it a pretty reliable mb.

                    The sound issue is still there. I fixed that too by putting a cheap sound card in it.

                    Thanks to all of you!

                      Re: Old GA-7VT600 missing caps

                      I know this is old, but did you check the jumpers on the front panel audio header?

                      Some boards require jumpers to redirect the sound to the rear ports if you don't plug in a front panel audio connector (which have a loopback feature inbuilt)

                      Download the manual and have a look, it should confirm this

                        As a general rule of thumb, AC97 audio needs the jumpers, but HD audio doesn't.
                        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

                          wow I wish I could get this board working. I have a working XP 3000+ E that would be so cool to use in this board
