Computer keeps crashing after I replaced the RAM

macbook-pro memory crash

I have an early 2010 MacBook Pro. I just upgraded the RAM to 8GB because I was constantly using more than 4GB. I have upgraded to flash storage as well so I didn't want my system constantly using swap. My MacBook keeps crashing constantly. Here is my error log:

Is my RAM defective? Should I just revert back to the original 4GB RAM?

Update:

I tested the RAM several times and I couldn't find the problem. I think that the RAM must have been bad near the beginning of the sequence so it was hard to find, but I'm not really sure. I just went to the store and bought new RAM and now my Mac never crashes. Thank you everyone for all of the help.

If you are having the same problem that I was having, just get new RAM, it is a lot less trouble and it will save you hours of testing your RAM (which is not fun).


Your system identifies the RAM correctly:

Memory Module: BANK 0/DIMM0, 4 GB, DDR3, 1333 MHz, 0x01BA, 0x202020202020202020202020202020202020 Memory Module: BANK 1/DIMM0, 4 GB, DDR3, 1333 MHz, 0x01BA, 0x202020202020202020202020202020202020

However, there is another problem with your

AppleIDAuthAgent

Try fixing it with this:

  1. Restart system in safe mode.

  2. If that does not work restart in repair mode ⌘ + R.


There are many reasons your Mac could crash.

To rule out memory, try running a memory test:

http://osxdaily.com/2011/05/03/memtest-mac-ram-test/

Additionally, you should double check that the ram you purchased runs at a supported latency. Use MacTracker or go to the website of the ram manufacture for a list of tested computers.

If you put the old ram back and the crashing stops, then that is as close to a smoking gun as you will find.

If the Memory test passes and putting the old memory back in don't fix it, the next place to look would be a corrupted OS

Try:

  • Repair permissions, verify disk
  • Boot into safemode (hold shift key while booting up your mac)
  • Disable all startup items and enable them a few at a time until the crashing returns
  • Create a new user account
  • If you have a spare hard drive, install a clean OS to it and boot from it temporarily.
