    Gigabyte GA-7VTXH+ Rev 1.0 Bad Caps.

    This motherboard has been alright i suppose it was the motherboard that came in the first "family pc" that my parents got back in 2002 i think it was. I guess nothing lasts forever. It's part of my younger brothers computer now and he was complaining to me saying "it would not turn on, i'm gonna buy a laptop now etc etc... because he is so inpatient" Well lol 5 minutes of looking and i think i have found the problem. Already soldered them out to show to you experts.

    Capacitors that have defo gone:

    2x Choyo 6.3v 1000uF (xr 105c) (the green ones)

    This 3rd one might actually be fine but i want to replace it anyway. the casing of the capacitor has always been loose but i think looking at the state of it now really i should change this!

    1x Choyo 25v 330uF (the black one)

    I am in the UK and not sure on where to obtain replacements. In my local town there is no place that sells capacitors

    The black cap looks like it is slightly bloated from the pic so I would replace.

    See "Where can I buy replacement capacitors"

      Yeah it also looks burnt on one side aswell so i reckon it probably has gone. Many thanks for replying.

        BTW, if you are faced with high shipping/handling, you might as well order spare capacitors as they cheap. You may want to get replacements for the other capacitors on the motherboard "just in case"?

        Most members of this board suggest Rubycon, Panasonic, United Chemi-con for brands to stick with.

          get rid of *all* Choyo and GSC (? ..the ones next to the fan wire on the 2nd pic) caps on that board.
          known junk.. they will fail.. just a matter of time.

          if recapped with good caps, this board should be working fine longer than with the junk caps it came with from the factory

            I tried the uk shops and i am faced with high shipping around £15 and am pretty put off. I'm sorry i made a mistake the 2x Choyo 6.3v (xr 105c) (the green ones) are obviously 1200uf and not 1000uf damn typo there!

            Most are choyo and there are a few little GSC ones in the top right hand corner of the board. There are the purple ones 4 of them not sure of the brand though "O st I . Q" ?? lol

            I would not mind replacing all the ones you say are gonna eventually fail but i don't want to spend out too much on the board as at this rate i would be better off upgrading his motherboard to something that is more powerful like a 400fsb board with agp8x and usb 2.0 lol.

              Re: Gigabyte GA-7VTXH+ Rev 1.0 Bad Caps.

              ebay might be your next best bet. You may not find all your caps at one source and there may be fakes sold on ebay, but many china sellers offer free shipping to anywhere in the world.

              You could just buy the noname, "not so good caps" and hope to get 3 or 4 years use out of them and then toss them.

              I'm in the same boat in Canada with high shipping costs so I order them from ebay. I try to find reputable sellers, ask for pictures, and with reasonable shipping costs.

                ebay.co.uk examples (can't vouch for seller or product), but prices are more reasonable (some are low ESR caps)

                  Re: Gigabyte GA-7VTXH+ Rev 1.0 Bad Caps.

                  Well i found these by panasonic what do you think ?


                  Replacement for 1200uf caps ??

                  They sound like the right spec not a lot of info i have asked they seller for more info and if he has got a single 25v 330uf aswell.

                  In the meantime aswell i just put an Abit NF7 and and an EP-8KRA2+ on my ebay watch list. My brother always complains about moving massive amounts of music on and off his Nokia N97 so he could really do with the upgrade to usb 2.0. My first priority though if i can get the board going again then that will be fine. Then i will proceed with getting together high quality caps for the board or just upgrading his pc a bit.

                  Thanks for the links i am looking through now i will go for the best quality ones i can find on there like Panasonic or Rubycon ones perhaps. No more of this Choyo nonsense lol.

                    Quality name, but Panasonic makes several types of caps. Ideally, you want low ESR caps. Wait for the seller to respond and post back. Hopefully, the seller also has a 25v 330uf as well. Seller has great feedback so I wouldn't be too worried about getting ripped off.

                        those 25V 330uF choyos can be safely replaced with 16V caps.
                        no idea why, but gigabyte liked to use those 25V choyos back in the days of Socket A and S. 478 (Pentium 4), even though most places where they were used on the board are 5V and below.
                        due to the fact they used them in some places with 12V going through them, 16V caps are safe to be used there if you dont have the equipment/time/whatever to measure the voltages on all cap spots. (or if you're lazy like me )

                        for the 25V 330uF choyos
                        http://cgi.ebay.co.uk/300366972277
                        (yes, those are 8mm dia, the choyos are 10mm.. shouldn't be a problem for a guy with needle nose pliers though )

                        for the 6,3V 1200uF GSC's
                        http://cgi.ebay.co.uk/300355937594

                        a list of all the caps on the board would help to find replacements. OST aren't the best either.. they fail without any visible signs of failure quite often..

                        by the way, when you finished recapping this board (and it works), just get a cheap PCI USB 2.0 card with a NEC chip on ebay.
                        Cards with VIA chips are usually cheaper, but tend to be a painus in the anus to get or keep running.. (dumb down to USB 1.1 mode, devices not recognized and other crap)

                        PS: the 25V 330uF choyos and g-luxons (yes.. they even used mixed caps on a single board.. with both brands being crappy) i pulled from a gigabyte pentium 4 board from that time period showed no visible signs of failure, but almost all of them had leaked and dried out from the bottom of the cap (rubber bung). no wonder that board froze up all the time or didn't POST properly sometimes..
                        just shows how bad those crap caps are. amazing that your board worked for so long

                          Re: Gigabyte GA-7VTXH+ Rev 1.0 Bad Caps.

                          oh well... look what i found while googling for some pics to find out what caps are on that board and where they are located...

                          https://www.badcaps.net/forum/showthread.php?t=257

                          going for 16V 1000uF for those choyos is a bit overkill imo.. but as topcat said in that thread, it works perfectly..

                          another idea for the CPU area would be to replace the 4x 6,3V 3300uF caps (i guess OST on your board?) with 9x 1500uF 6,3V (fill the empty spots)

                          -----

                          before submitting this post, i just put this together (quick & dirty in ms paint).



                          using those caps:
                          12pcs. 6,3V 1500uF Panasonic FL (yellow & yellow-green dots)
                          http://cgi.ebay.co.uk/300355937594

                          15pcs. 16V 1000uF Panasonic FK (red spots)
                          http://cgi.ebay.co.uk/290416806311

                          i don't know for sure if the FK series are good enough though. feedback from other recappers?

                          anyways.. if you go for the above, total cost would be 12.98 US$ / 8.79 gbp for a board that's going to last longer than with the crapcaps it came with from the factory, plus you have 3x 16V caps plus 1x 6,3V cap as spares in case you mess up while soldering or something..

                            Yeah i saw the other thread earlier regarding the 7VTXE. I don't know how this motherboard has lasted so long either it's pretty maxed out with an amd 2400+ cpu i cannot get anything faster on it.

                            I could do with the soldering practice to be honest, and seeing you gone to the trouble of mapping out the board in good old paint i might aswell give it a shot. The new capacitor layout will be an interesting task. I'll order everything off the bay tomorrow hopefully. Nice one Scenic.

                            USB PCI NEC

                            How about this one for the motherboard ? I thought adding one of these to the motherboard it might just only run at the 1.1 speed or something lol. I'm learning

                              that card would do just fine.
                              if you spend a little bit more you won't have to wait 2 weeks for the card to arrive from hong kong btw :P
                              http://cgi.ebay.co.uk/260320213044

                              the speed the USB ports can run at is limited by the capabilities of the USB controller (the NEC chip on those linked cards).
                              the onboard one is only capable of USB 1.1

                              using that card instead of the onboard USB ports, the speed should go up from somewhere around 1MB/s (USB 1.1) to about 35MB/s (the maximum USB 2.0 can do ; also depends on the connected device though)

                              (i'm talking about real life speed here.. not the bogus theoretical max. transfer rates manufacturers tell you)


                              edit: those 480MB/s you read everywhere is in megabits per second (not megabytes). 480MBit/s is 60MByte/s. but that's the *theoretical* maximum transfer rate, not including all the protocol stuff that also has to be transferred.. just marketing crap to make it look better than it really is.. as usual..
