    Northbridge TEST

    Hi all


    Is there a way of testing a Motherboard Northbridge ??

    I've heard it should be checked the smd capacitors placed in CPU Socket as well as a mosfet near Northbrigde.

    What is your opinion??

    Thanks in advance
    Regards!

    Re: Northbridge TEST

    The SMD capacitors in the CPU socket [at least most of them] are on Vcore and don't have anything to do with the Northbridge.
    They are small uF and there to filter out noise frequencies higher than the Ripple from the PSU and VRM MOSFETs.
    - AKA: 'EMI' or 'RF noise'.

    The best way to test a Northbridge is to test the Motherboard.

      Do you mean I first must check if the other parts of the MB work ??

      Thanks for responsing!

        Basically drop a CPU, some RAM and a video card in and see if it powers up... A POST code card helps a lot if the monitor doesn't come up. If you don't have one, buy one, coz they're dirt cheap on dealextreme. I don't have one yet but i plan to get two... one for PCs one for laptops.

          The Northbridge is basically the main controller chip for the whole motherboard.
          Has MANY functions that would need tested.
          Only practical way to test one is to test the whole motherboard.

            Hello again!

            I've also heard other way of knowing when a northbridge is faulty is if one or more of the capacitors on it has/have a resistence value less than 30 ohms.

            they'd usually have a much greater value


            Does anyone have an experience/comment with this test?


            I just tested my NB and really some of the capacitors have aprox. 400 ohms and the others have 1, that is, open!



            Regards!

              Considering you have no clue what your doing the answer is no.

              You cant just start measuring capacitors and find one under 30 ohms and say the northbridge is faulty. The only true way (without removing the chip and placing it in test equipment setup just to test it) is to have the board boot and insure you have no northbridge issues.

              Considering you never said what the problem was and what board it is my guess is you picked a word (northbridge) and started talking about it like you knew what you were doing. That isnt going to get you alot of help.

                That will tell you nothing.
                Caps in or near a Northbridge can have parallel components.
