What kind of idiot...
…accidentally buys DDR3-1066 (PC3-8500) when he meant to buy PC3-10600 (DDR3-1333)!? This is why I am not a “hardware guy”. I have no patience for figuring out some rather obtuse and arcane combinations of numbers and letters that mean the difference between a computer working correctly or not working at all. Oh wait. That sounds like code.
