    Problem with Dell Inspiron 530S Cannot do dual channel, even with matched RAM

    Even when it's a 775 board! Also manufactured in 2008.

    It appeared to be fine in early August or late July!


    Now, the following will occur:

    If I try to use both channels, the BIOS will go bleep--bleep--bleep--bleep-----bleep--bleep--bleep--bleep and repeat!

    Or I just get turbo fan!

    The board only is usable in single channel!

    Did you try each stick separately?
    A man convinced against his will is of the same opinion still.

      Bad Northbridge?
      Incorrect RAM voltage in BIOS?
      Noisy vCore or VRM in general from bad caps?
      Timing/speed of RAM correct for board?

        No Vcore problem and the timings are right. Also using a matched dual channel kit.

        And the PC appears to be fine in single channel.

        It cannot be Vcore if I'm able to install Vista and apply all service packs in single channel. Zero OC'ing.

        And with a bad northbridge, Windows installation should have failed, even with single channel.

        I'm been wondering if I need to reflow the solder for the DIMMs?

        The board only has a fit if I populate the other half of slots.

        The northbridge appears to be a P35.

          Bull. It's not that 2.1 V crap, and you cannot change the VDIMM in the BIOS.

            How about running Memtest86?
            Had a matched set of Corsair do that after 3 years.
            BIOS set to do the "full" checking on boot instead of quick?

            PS: Got another board to check sticks in?

              Not true windows can and often does install fine with a partial failure of the northbridge relating to memory management.

              More information would help like what speed is the memory you are trying to use have you trying lowering the speed when using both sticks. Are you installing the pair in the proper slots 1 and 3 or 2 and 4. Try a single stick in each slot 1 slot at a time.

                Unless you mean just a dead channel. And I can't change any frequency.

                Interestingly, it seems I also can't populate any of the slots on the other half.

                It seems that I have to put RAM in the white-marked slot and the black one right next to it for it to boot!

                  did you try both dual channel pairs? a lot of boards require a certain slot populated first or else it goes bleep-bleep like that...

                    It don't matter which slot and even with the RAM that appears to be the original!
                    (Samsung of 1 GB total 512MB x 2) (Like on my Asus P5QL Pro)

                    Samsung appears to be typical for OEM.

                      sounds like you have a bad northbridge then.

                        So you are saying slots 1 and 2 work but 3 and 4 fail when you just try 1 stick testing 1 slot at a time? If that is the case then it sounds like the northbridge to me maybe a bad mosfet if you are lucky. I use this http://www.drivestar.biz/desktop-ddr...led-p-461.html its handy.

                          Interestingly, it seems that I can use both slots on one side, but not the other:

                          Like this:

                          11 00


                          And not:

                          10 10

                          Nor:

                          01 01

                          Nor:

                          10 01

                              dual channel for that board should be either

                              10 10 slots 1 and 3

                              or

                              01 01 slots 2 and 4

                              checking each slot 1 at a time using only 1 stick

                              10 00 slot 1 does it work?
                              01 00 slot 2 does it work?
                              00 10 slot 3 does it work?
                              00 01 slot 4 does it work?

                              if those tests pass then test with 2 sticks at a time and try.

                              11 00 slots 1 and 2 (this is single channel mode using channel A) does it work?
                              00 11 slots 3 and 4 (this is single channel mode using channel B) does it work?

                              if all those tests pass then try.

                              10 10 slots 1 and 3 (this is dual channel mode using both channels) does it work?
                              01 01 slots 2 and 4 (this is dual channel mode using both channels) does it work?

                                if those tests pass then test with 2 sticks at a time and try.

                                11 00 slots 1 and 2 (this is single channel mode using both channels) does it work? -> Yes
                                00 11 slots 3 and 4 (this is single channel mode using both channels) does it work? -> Yes

                                if all those tests pass then try.

                                10 10 slots 1 and 3 (this is dual channel mode using both channels) does it work? -> Failed! (usually repeated bleeping)

                                  Looks like a bad northbridge then im afraid. You could teats all the caps and the mosfets but my guess is they will test fine.

                                    You might also try another CPU. I have seen rare cases where a bad CPU prevented memory to work in dual channel mode. But that was only on AMD cpus, never seen it happen with a intel cpu its always been a bad northbridge.
