    I just installed a new ssd in the Mac Mini with the hopes of an Internet recovery to the ssd in order to recover data from the stock hard drive. The stock drive was accidental repartitioned wrong during an Ubuntu install. The Mini is a late 2011 i5 base model that had been upgraded with 8gb of crucial memory and worked fine for the last couple years.

    Enough history, I've had the same issue with internet recovery to an ssd that others have had but in the meantime I decided to do hardware test just to be sure. The top memory stick didn't pop in as easy as you would hope which prompted the test.

    The first error read.... Error 4/MEM/62/40000000: 0x84525190
    After swapping the two .... 4/MEM/60/40000000: 0x84495f90

    Is this enough info to tell whether it's bad memory or a messed up socket?

    So you have two 4GB chips in there? I would try the test again with just one chip in at a time to see if that narrows it down to one of the chips.

    Thanks for the suggestion, it's funny that both dimms were fine in the lower slot 1 at a time. Together, I would get one of those errors. Also trying to get internet recovery to work I removed the factory 500 Gb and put the ssd in the primary spot with the factory cable. The OS finally installed and the memory errors went away.

    I'm happy with the results but don't really know why any of the things I changed made the difference and eliminated errors.
