Hi all, I have a mid-2012 Macbook pro i7 with 2x4Gb memory. I started getting an issue where the system would make a fuzzy screen, crash, and then beep-three times with a blank screen on start-up. All these signs indicated a RAM issue. I took out one ram card, but still got the issue. Swapped it to another slot, but still got the issue. This implied that the RAM card, not the slots, were at fault. I then took the other ram card and placed it into one of the slots. And sure enough didn’t get any crash for the next week or so (however, it was really slow running on only 4Gb). I decided to upgrade using your recommended memory for my model: with 2x8Gb. After it arrived, I replaced the memory, but started getting different style crashes. Approximately once a day, I will get a random shutdown and automatic restart. It then goes to a grey screen saying it encountered an unexpected shutdown. I have tried a PRAM and SMC re-set, and it crashes with or without an external power supply. Could it be the new RAM is at fault or is this a re-incarnation of the previous issue? Any advice would be greatly appreciated.
