    Intel D975XBX Cap Mod Questions

    I would like to replace all the caps on this board.

    1. What are the BEST caps money can buy?

    2. What make/model/quantity would I need?

    Thanks!

    Welcome Zorlac,

    Oh no! Please don't tell me that the new intel-brand board based on the 975X chipset already has bad caps! Or do you simply not trust the Nichicon HN that intel uses after the incident with Nichicon a few years ago?

    As for the "best" replacement caps, well, as with anything "best" or "most", it's a subjective matter. Certainly from what I have seen around and learned on this forum, I would recommend either Rubycon MBZ or Sanyo WG, if you seek maximum reliability in low-ESR caps. United Chemicon is also a very good choice as far as cap brands go.

    Regarding make/model/quantity: well, quite simply, look at what your board uses now, and choose caps of identical specifications or, failing that, slightly higher, both in terms of voltage and capacitance.

      I have just built a system with this motherboard. Why is it necessary to change the caps?

      160Gb WD SATAII Server grade

      160Gb WD eSATAII Server grade for backup.

        I just want to replace them for better OC capability, longer lifespan, better stability, and the bling factor! LOL

        So are "Aluminium Electrolytic Polymer Capacitors" better than "Aluminium Electrolytic Wet Capacitors"?

        These are the caps I was told that I need:

        6.3v 820uf for pcie/ram/pci
        16v 470uf for pwm
        10v 330uf for others

        Also, how would I go about finding out which caps I can just remove without replacing? For instance, I have no need for the onboard sound, parallel ports, serial ports, PS/2 ports, IDE, floppy and probably a few other things I am not thinking of...


        EDIT: Rubycon MCZ seems to be lower ESR than MBZ. Why do you recommend MBZ then? ...just curious

          if you want to OC, why get yourself an original intel board?
          for OC you should look at stuff from asus, msi, Abit, DFI...
          for longer lifespan, better stability see the Gigabyte DS series boards with All Solid Capacitor.

            I agree with this point.

              I'll third that. Intel boards have a reputation for being stable, but not good OCers.
              You know there's something wrong when you open up a PSU and are glad to find Teapos.
              Why I don't buy cheap cases!

                Re: Intel D975XBX Cap Mod Questions

                I have my reasons for liking Intel boards...any way, back to to my original questions:

                I just mapped out my board with all the capacitors I will need:

                6.3V, 220uF
                6.3V, 3300uF

                10V, 470uF
                10V, 1000uF

                16V, 470uF
                16V, 1200uF

                25V, 22uF
                25V, 33uF
                25V, 100uF
                25V, 220uF

                And the final three are a little weird...no clue what they are. They have the following markings:

                611 561 2.5V
                612 561 2.5V
                613 561 2.5V

                So again, Solid or Liquid capacitors...which are better?

                  Re: Intel D975XBX Cap Mod Questions

                  intel boards have different capacitors depending on which revision of the board. better to post some pics of your board (preferably from different sides) so we can advise you what to replace.

                      that doesnt help, i dont have info about all boards

                      611 561 2.5V
                      612 561 2.5V
                      613 561 2.5V
                      these are polymers. but do you only have 3?



                      this revision has 8 sanyo oscon sepc. one of the best for vcore.

                            I gave the voltage and uF of each cap above. Do you need the Manufacturer too?

                            Oh, and the pic above...I have 9 caps total. The first marking is on the motherboard. The second set of markings are on the cap:

                            C2D1 = 612 561 2.5V
                            C2D7 = 613 561 2.5V
                            C2D9 = 613 561 2.5V
                            C2E1 = 611 561 2.5V
                            C2C1 = 613 561 2.5V
                            C2C2 = 612 561 2.5V
                            C3C1 = 613 561 2.5V
                            C3C2 = 612 561 2.5V
                            C3C3 = 613 561 2.5V


                            That pic is from a rev 302.

                                Also, what do you mean by forget those caps? Which caps (Voltage/uF) would I use in their place? Or are you saying I do not need them at all....or leave them as is (do not remove them)?

                                  dont remove any cap. i say forget those cos they are so small.

                                  the red silver are probably fujitsu

                                    Okay...then it looks like this is the list of caps I need (Guess I will leave the vcore caps and the little caps not worth replacing):

                                    (3 total) 6.3V, 3300uF

                                    (19 total) 10V, 470uF

                                    (3 total) 10V, 1000uF

                                    (4 total) 16V, 470uF

                                    (4 total) 16V, 1200uF

                                    1. Should I get solid or liquid capacitors?
                                    2. Depending on the answer to #1, which brand?

                                      All values you quote are liquid cap specs.

                                      Now you need Rubycon or similar. As you are in the USA contact Topcat. Owns this forum and specialises in supplying the right quality caps.

                                        MCZ are also great - I mentioned MBZ due to the fact that availability of MCZ is not always that great, and either of the two will, realistically, perform equally well. Specwise, MCZ does have lower ESR than MBZ, indeed.

                                        Here you find a high-resolution pic of the board in question, in which many of the caps are identifiable (NB: this does *not* mean that every unit of this board will have these same caps, of course). Visible are Nichicon, UCC, and a number of Sanyo. The 3300uf, 6.3v ones are Nichicon HM(M), as is typical for intel-brand boards.
