    680i Reference Board - Samxon Vs Rubycon vs Solid

    I've got a reference 680i T1, which I've just traded out via RMA with a reference 680i BR which just pulled a C1 memory killer on me. One thing I've noticed was that the boards used different caps

    The BR, the first revision, used samxon caps on the PCI/PCI-E slots and in random, smaller places - but used Rubycon MCZ 16v 1800uf on the right hand corner, on top of the ATX 24 connector, and several other Rubycon MCZs to the left of the CPU.

    The T1, the new revision, uses exclusively samxon caps throughout the entire board. The 16v 1800uf MCZs have been replaced by samxon 16v 1800uf GC(M) along with the ones to the left of the CPU.

    I've looked around and it seems that samxon and rubycon GC and MCZ seem to be neck and neck, with the MCZ being slightly better but would it be worth it to trade out the samxons with MCZs?

    Also, I've noticed several, non-reference 680is that use all solid caps. for example - this MSI http://www.pcstats.com/articleview.c...id=2182&page=1. Would it be possible to recap my 680i board with solids? Also, I've noticed that the solid caps seem to have lower capacitance... but yes I realize that ECR is better on solids than electrolytic caps... but 1800uf MCZ vs 470uf solid? Are solids that earth shattering against MCZs in motherboard apps when overclocking? Lastly, are the solids more sensitive to heat than electrolytic when soldering?

    I'm sorry for all the questions, I'm a total n00b when it comes to the finer points of recapping. I've attached some pics of the new board along with a single pic of the MCZ on the old board, which I just sent back in. Thanks!

    Solid caps hold about 3 times the change vs an electrolytic cap

    The Samxon vs Rubycon caps you mentioned are just as good, no idea to switch either way... What could make a difference would be to go with solid caps.

    But why do you want to change them? What benefits are you looking for?
    Realistically you will gain next to nothing by doing this recap job if it's just for overclocking...

      no.
      solid polymers have much lower esr than lytics.
      also better at high frequencys.
      much more durable at high temps/ripple.

        can replace cap using solids at about half the capacitance.

          Replacing electrolytic caps by solid caps on old motherboards
          by madscientist750
          I do have several old pc motherboards which i recapped 10 year ago and some of those caps are bulged now.
          I would like to upgrade them using solid capacitors. I do use them for testing and helping some alternative operating systems.
          I would like to ask if such an upgrade can be done, what should i have in mind when replacing electrolytic by solid caps and if such thing exist, if there are caps list for old motherboards. I would have to figure out what caps needs each motherboard and then prepare a list to try to ask for them on some electronics stores.

          Reference Nvidia GTX 980 ti - looking for a new shroud
          by speaktorob
          So a while back, to deal with the fan noise of the old blower style shrouds on the reference cards, I chucked it and installed the monster that is a Raijintek MORPHEUS 8069, with a couple Noctuas on it. Did the job but quite unwieldy tbh.

          Anyone know which boards would have a compatible shroud for it? I know the EVGA used the reference board but wondering if any other manufacturers did. I want to put something sensible back on it, but I'm having a hard time getting hold of even a faulty reference board for a reasonable price.

          Hello,

          I would like to know the reference of a QFN-20 because the reference marked on the chip does not give anything...
          PC Reference : HP Pavilion - 15-cs0006nf
          Motherboard : DA0G7BMB6D0 rev D
          Reference marked on the chip: AWVAIL
          Type : QFN-20

          I didn't find a boardview or repair schematics

          Thanks in advance...

          Can I replace KME cap with Samxon GF cap?
          by chth96
          Hello.
          I have 29inch LG CRT TV,And Yesterday,Whenever I connect AC power cord to power outlet without switch on, I heard a sound like white noise, And When I switched on this CRT TV, It sometime displayed correctly But usually It won't last more than 20 minute and The screen begin to dark and It finally did not display at all for hours..
          Today,I dismantled its plastic case and discharged the biggest capacitor(400wv 470uf) which still holds 250 voltage,and I finally detached PCB from cathode-ray tube.
          I measured ESR value of most of caps in PCB with MESR-100 and I found that KME(25v...

          XPS 9520 not powering up. Solid orange led
          by Weelcup
          Hi friends

          I have a dell XPS 9530 which had some liquid damage to the usb area. I replaced both the usbc iCs and not I can see 20v on the meter. But it does nothing and the 20v is not passing to charge the battery or turning on the board either.

          I suspected the PD controller (usbc controller) but it will need to be flashed if I decide to replace it. I thought that if the usbc controller needs flashing then at least the board should turn on on the battery. I charged the battery externally and attached it to the laptop. Now the 11.8v is actually passed to the board I can...
