I tried to install some new Crucial RAM - 4GB - into my MacBook Pro (Penryn).

I snapped it into place and when I replaced the battery and tried to boot up, it started this alarm-like BEEP BEEP BEEP at me, only stopping when I took out the battery. Very frightening ...

I tried again and the same thing happened. Very, very frightening...

But when I put the original 2GB of RAM back in, it booted up like normal.

What did I do wrong? What's happening? Help!

MacBook Pro, Mac OS X (10.5.2)
