    DH55HC Memory Issue

    Biggie81

      Hello Everyone

      I have a DH55HC Mboard with i3-560 processor

       

      i had a 2G memory stick from kingston installed for few years - 2GB-PC3-10600 CL9 240 DIMM (KVR13333D3N9/2G)
      and all worked well

       

      now i decided to add some ram and purchased same model of memory but 2 sticks of 4G each

      installed them on the blue slots. Bios is up to date and shows them working at dual channel 1333 speed

      but when i turn on the pc and work on windows, every time i get a blue screen error. "Memory management" IRQL" etc

      i did a memtest86 on the memory - no problems found.

       

      when i take out 1 stick - the pc works flawless! but when i add the 2nd again - blue screen hysteria.

       

      what can be the problem?

       

      thanks

          Try putting the DIMMs into the black sockets and see if the issue remains...

            Hey

            thanks for your reply

            installed the 2 dimms to 2 black sockets.worked well for an hour or two and then started BSOD again
            checked mem86 right after restart - showed some errors.

            disconnected DIMM checked each seperatly on mem86 - all good

             

            Bios settings set to "optimal defualt"
            maybe its some voltage issues? all run on 1.5v

              In the general scheme of things, ignoring a failure within the processor or within the DIMMs themselves (though these are both possibilities for point of failure as well), the memory channels can be disaffected by noise introduced by the processor, noise introduced by the motherboard and noise introduced by the DIMMs. In many cases, the reason why folks have more problems when using 4 DIMMs (instead of two) is because of noise (the additional noise from having a second DIMM on a channel pushes things past the noise failure thresholds). Secondly, putting a single DIMM in the black connector can be problematic because of reflections occurring behind the DIMM (at the blue connector) (and yes, trying this was a desperation suggestion). Thirdly, as a motherboard ages, noise will increase on the memory channels due to oxidation, component degradation, etc. and etc. Your board is approaching being 6 board generations out of date and 7 years of age - which is the typical MTBF (Mean-Time Between Failures) for most of the components used.

               

              Bottom line, you likely are having intermittent errors occurring on the memory channel(s). You could try using a different set of DIMMs, in order to see whether this improves the noise situation (and, as I said, it could still be a failing DIMM issue), but my recommendation is to not throw good money after bad. It is time to consider replacing this equipment completely...

               

              Hope this helps,

                Hello Biggie81,

                 

                Bear in mind that you have a Legacy Intel® Desktop Board, drivers and BIOS updates are limited to those that can found here; Downloads for Intel® Desktop Board DH55HC. From my end, my recommendation is to stick with the 2GB of RAM and this because the availability of the drivers. It's difficult to troubleshoot your motherboard especially taking into consideration that the latest update was in 2011.

                 

                Regards,

                Amy.
