Hey everyone, I just bought a 4 gig kit from new egg for my macbook pro 2.4 core 2 duo early 2008 running 10.6.3. I installed the ram and it ran fun. Went through some stressing and everything was smooth. This morning, I was watching a flash video and my mac froze and did the SoS beeps. I force shut it down, turn it back on, and I get the 3 beeps which mean "bad ram". I switch out this ram for my old 2 gig kit and it runs fine. I then replace it again with the 4 gig's. It runs fine now! My question is, is this normal? Could the Ram be "dying" or does Ram just go out all at once. Should I get this replaced while it is still under warranty? I don't want to send it back in for them to not be able to re create the problem. Thank you!
