Can anyone suggest a good place for RAM for the new 15" AlBook? I had bought an extra 512MB chip from datamem.com before my AlBook got here and when I installed it I started getting kernel panics a lot more often. When I just removed the extra chip, the panics stopped. So can anyone suggest a good alternate place to get 512MB chips that actually work or has anyone bought from datamem.com and actually received a chip that worked? Any info appreciated. Thanks!
