I run a small repair shop and have noticed that, in the last six months or so, I have seen about 10 different 13” 2016/2017 Macbook Pro’s with defective RAM. Both the touchbar and function keys model. Have others seen the same? Is this yet another “gate” that plagues these models? Update (06/12/2021) The Macs freeze unexpectedly, after a while they fail to boot as the OS gets corrupted. The built-in diagnostics often doesn’t spot the problem, but memtest86 always picks it up. Here is an example screenshot:
iphone3ghulp - That was useful! As I stated: “Being a much higher density package its possible heavy RAM I/O could be an issue.” Are these folks doing heavy processing like video editing or other heavy graphics types of stuff? Why I ask is I’ve seen a few 13" with RAM issues, but not 15" models, yet they are using the same RAM. But, unlike the 13" systems the 15" have a discreet GPU and VRAM where the 13" models use the systems RAM for video buttering! I also bet these systems fans and heatsink fins are also loaded with dust so the systems cooling is reduced!
I have almost the same problem, only a macbook pro retina with a 15 inch touch bar (2018). I did not work on it for very long, as it is a backup laptop (judging by the information on the smart disk for 2 years - 60 hours of operation). I had a panic kernel, but I did not pay attention because they were one-time, I thought it was an OS problem. The other day I started working on my laptop again and reinstalled the operating system and again I rebooted. After that I ran memtest86 and it showed a memory problem. The laptop is no longer guaranteed, although it is actually new, and perhaps it was defective from the beginning, what to do is not clear.
