Re: MemBist error: DIMM A4, D5

I have seen this error before and this can indicate that you have DIMM faults or they are starting to get faulty. What i usually do when i have this kind of error is to try and reseat the memory dimms in another slot and boot up again to see if the same error occurs in the other slot.

If this does not work then its to call Dell support to replace the faulty dimms.

Best regards Boris
