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?
