Looking for quick minute of your time. Going to upgrade to 4 GB (2x2GB) of memory: DDR3 - PC 8500 - 1066 MHz - 204 pin SO-DIMM Rather than just buying cheap memory for my new MacBook, I read some reviews and was totally confused on which is the best memory for the new MacBook. Whether people bought at NewEgg.com or MacSales.com they seemed to have same success rate. And brands like Crucial got around 90% success rate but around 10% had a problem. An example, a few people that bought Crucial RAM for their new MacBooks did not have success on first try. So, is this a bad brand or is it just one or two bad sticks of memory??? So, if you updated your MacBook with 4 GB of memory, where did you buy it and what brand did you buy? Any problems? Basically, I just want to buy the brand with the highest success rate. I just don't want any problems. I know they SHOULD all be the same. DDR3 - PC 8500 - 1066 MHz - 204 pin SO-DIMM Thanks for your answers.
