Macbook Restarts Automatically After RAM Changed

I have a MacBook Pro with OX 10.9.3 installed having 5 Gb of RAM. Yesterday I changed the RAM, and since that, my MacBook restarts automatically while working. I thought it was an issue with the new RAM, so I removed the extra RAM, but still getting same problem.

Here is the log of my Unexpected restart of the machine :
