    Re: i7 920 SMD capacitors/resistors

    nope tried again, still no dice.

    Its a bad idea to put in a smaller cap right?

    could someone else with a i7 920 please try testing their caps for me?

        I'm not sure what that means.

        That's hard to say without knowing what it's connected to.
        If it's in a bank of parallel caps you might not need it at all.

        I don't have one myself or I would.
        I use skt 771 Xeons or C2D and that's actually more than I need for anything.

            Or maybe you measured the total capacitance of a bunch of them in parallel.

                    bingo!most of these caps are on vcore.
                    some may be pullup/pulldown resistors.
                    if damaged this may cause misreporting of type mentioned earlier.

                        good point, but I was using the electrodes from point to point of the cap, would like to avoid de soldering good ones but any way of telling if I am?

                            you are.
                            remove any that are chipped/cracked too.

                                14uF is possible in smaller SMD ceramic, but I kind of doubt it.

                                    The closest I found was too big and about $14 each.

                                    At that price by the time you bought enough to fix that thing might as well have bought a new CPU.

                                        well if I have to remove them I will I guess

                                            Ceramic capacitors/resistors - do suppliers matter?
                                            by spleenharvester
                                            I want to buy one of those SMD component books so I don't have to spend as much time searching my scrap boards for what I need, specifically ceramic caps and resistors as they seem to be what I spend most of my time replacing. But the only ones I can find are no name brands. Does manufacturer matter as much for SMD parts as it does with electrolytics or is the generic stuff likely to be fine?

                                            Hi,
                                            I seem to have lost 2 resistors or capacitors while experimenting on the HP 850G6. Now nothing works anymore.
                                            Can anyone tell me the position and values?
                                            The ones I am looking for are on the BIOS chip. I have marked them in red in the picture.
                                            Thank you very much​

                                            Hey everyone,

                                            I'm currently working on a mid-70s Sharp Electronic Digital Clock Radio, Model FY-70CH. I found the service manual online, printed it out, and have been studying it for a while. My main reasons for tackling this are: (1) I want to learn electronics and figured I'd start with something I had on hand, and (2) I want to fix its issues. Right now, the radio sounds awful, has about 5V DC at the speaker terminals, and the alarm time setting doesn't work. But I'm not asking how to fix these problems.

                                            Instead, here's what's been bugging me so far:
                                            The schematic...

                                            power on.

                                            hey all, iv got my favourite battery charger here which iv had for many years probably 15 years now or maybe even more. it still works good but thought id open it up to clean the dust out of it, lots of dust inside but now its clean and noticed 4 capacitors inside it and wondered if i should replace them.
                                            it has inside:
                                            2 x 47uf 16v caps 105c branded as Su'scon (lol sounds sus to me)

                                            not heard of these brands are they any good?
