A moment ago, I popped in the Crucial PC2700 SO-DIMM stick of RAM that I bought from newegg.com (mentioned on a recent thread concerning RAM for a 15" PB) into my 17" 1.67 Powerbook (purchased this past May) and it didn't recognize it at all! When I booted the computer up, it could only see the factory Samsung 512. So I yanked out the Samsung and popped in the Crucial by itself. When it was booted up, it made these beeping sounds (most likely meaning, "hey, I don't see any RAM, so no start up for you"). Anyone have any recommendations or suggestions for the 17"? Most of the reviews on newgg.com were successful installs into 12" and 15" Powerbooks, but I figured they all use PC2700, so what the hey? I guess the logic board on the 1.67ghz models are more picky about RAM. I need a bit of insight before eating the 15% restocking fee when I return the product or sending it off for a replacement stick. Any help is appreciated, especially if there's anyone who knows from personal experience on a 17" Powerbook, thanks!
