    Hey, I have an Early 2008 MBP, and I ordered the matching 4gb Crucial ram upgrade kit. So, I installed both modules, and nothing. Screen's blank, I can hear the disk drive kick in, but nothing else. Keyboard's totally unresponsive. I tried starting it with one module in, that's one of the new ones, and I get the same response.

    However, when I start the computer with one of my stock ram modules with either of the new Crucial modules, it works; registers as 3 gb, and shows the module as being okay in System Profiler. I'm out of ideas. Anyone? :confused:

    Is it possible, or have you tried to seat them again once more after you saw 3GB register?
