    need a lil advice on recapping ECS HP MCP61PM-HM

    Hello,

    I got about 4 of these boards that need to be recapped. On all four its the same caps, 9 of them bulged up.
    TK 6.3v 1800uF

    Now the boards have another 3 caps:
    TK 16v 1800uF

    the 16v's seem to look fine, no bulging or ooze.. Should I be replacing the other 3 caps since they are of the same brand?

    Thanks

    Yes, replace all caps of this brand. Look around this site you will find recommended caps: Rubycon, Panasonic (Sanyo), United Chemi-Con and Nichicon. Post a list of all the caps on the board, their uf and Voltage. People here will give you suggested replacements.

      thanks for the reply bigbeark, here is whats on the board:
      TK 6.3v 1800uF
      TK 16v 1800uF
      OST RLS 6.3v 1000uF
      G-LUXON 16v 470uF

      And like i said only the 6.3v TK's are bulged but i'll replace all the TK's, how about the other two OST and G-LUXON? and does the height matter when replacing them? I found these on ebay to replace the 1800uF TK's:

      OST 6.3V 1800UF

      Component Ratings
       
      Capacitance = 1800uf
      Voltage = 6.3V
      Temperature = 105Âșc
       
      Mounting Type
       
      Radial Thru-Hole Snap In
       
      Dimensions
       
      Diameter = 8 mm
      Length = 20.5 mm
      Lead Spacing = 3 mm

      and Rubycon MCZ 16V 1800UF LOW ESR for the other TK's, is OST good enough to replace or should I go with one of the ones you suggested?

        Is best to replace all of those you mentioned.

            ost, g-luxon, and tk are all low-quality. it is also not recommended buying capacitors off of ebay because they use 99% counterfeit. recommended are rubycon, samxon, panasonic, chemi-con, sanyo, and nichicon, along with a few others. here at badcaps.net he carries rubycon and samxon.

              For the 16v TK caps, use these or these
              For the 6.3v TK caps, use these
              For the OSTs, use these
              For the G-Luxons, use these

                thanks a lot guys, lots of good advice given.. Does it matter if I get a 18mm or 20mm (height)? lead spacing, is that calculated by the diameter? and c_hegge the 16v TK caps you refer to.. the links has two different uF ratings.. the originals were 1800, the ones you link to are 1800 and the other is 330? and thanks for taking the time to drop those links.

                  seems like a mistake to me. theres no reason to link to a 330uf cap...unless you want a broken computer

                    alright thanks thats what i thought. This might be a stupid question but is there any reason why on all four boards the same 9 TK 6.3v 1800uF have bulged and the rest look ok?

                      are they right next to the cpu? then it is because of two things: 1. high-stress apllication, because they are part of the cpu'd vrm (voltage regulator)...2. heat. because it gets hot over there

                        Ah no, wait a second.
                        The 330uf capacitor is a polymer capacitor, as opposed to the original electrolytic capacitor.

                        It is common practice among people with more experience, to use polymer capacitors in the VRM of motherboards, since the bulk capacitance is not important (apparently).
                        One day I'll read an idiots guide as to why

                          well they seem to be priced the same, so should i go with the polymer? i think the board has 3 polymers on it right by the bad ones.. can't tell what they are they got LF 820 Ăž 791 written on top.. and shovenose about 5 are situated around the cpu, 2 by the pci-e and 2 by the ram.

                            the 330uF are solid polymer caps. When poly-modding, you lower the capacitance. I have poly-modded this exact model before using 470uF polys, but kc8adu said he's done it with 330s and it works.

                            Poly caps would probably be better for long term reliablility, and since this is a fairly new board, I would go for it.

                            The LF polys by the CPU are Nichicon LF. They can stay. On the board I re-capped, I replaced the 6.3v TK caps near the CPU with more LF polys and the others near the northbirdge and RAM with Panny FJ.

                              so how do you tell what the ratings are on these LF's? If you say they are good for long term reliablity, I'd rather replace them all with poly's.. I can't find any 6.3v here for poly's..can you let me know what uF rating you replaced the 6.3v Tk's with and a place to get them from?

                                The second line on them. Those are 820uF. You don't need 6.3v caps in the CPU VRM out, since the voltage there is only the CPU Vcore voltage, which is less than 2v, so a 2.5v cap is ine there (which is probably all those LFs are).

                                  so i can replace the 6.3v 1800uF's with the 820uF 2.5v poly's? as you can see my extensive knowledge of caps is overwhelming! I've stared at them and have even touched a few!

                                    It will be fine with the ones near the CPU, but leave the others as electrolytics.

                                        - That is consistent with lay-out factory boards I've seen.

                                        Not much point in doing 16v side of VRM if you don't do the Vcore side too.
