My MacBook Pro 8,1 sometimes freezes randomly, and I think it may have to do with the RAM. I have 16 GB of Crucial 1600 MHz RAM, and I know the official recommended speed is 1333 MHz, but I've seen plenty of forums/users who say they use 1600 just fine. However, a month ago I was having some issue that required me to reset the RAM, so I turned off the computer and physically swapped the two RAM stick from their places. And then the computer started having some issues...when I restarted, it worked fine for a few minutes but then everything literally froze and I couldn't move the mouse, etc, had to force a restart.
I swapped the RAM into their original slots, did a few PRAM and SMC resets, and it seemed to go back to normal. Then I had to replace my battery so I did that a few days ago and the problem seems to have returned. It's working fine atm, and it only seems to occur shortly after restart. However, another problem I noticed is that most of the time when I reboot it as of late, the boot screen loads most of the way, freezes for a second, and then restarts itself, and then reboots normally the second time (except, of course, when it boots up and then freezes shortly after login).
I am currently using the computer now, and interestingly, it did *not* reboot once before booting like I described - it booted up a lot quicker than normal and stuff seems to be working fine.
Contacted Crucial and we did a RAM test and neither module seems to be bad. They said it was because the speed is too high (1600 MHz), and that a recent chipset update made my Mac more finicky about that, but idk if that's accurate.
Any thoughts/suggestions?
