Hi All, Just a quick question. I recently picked up a latest gen Macbook White Unibody (MC516LL/A, the last one Apple made) locally for a good price to get back into Macs and test out Lion. It came with the default 2GB of DDR3 RAM (2x1GB sticks) which I tried to upgrade to 4GB / 8GB (2x2GB or 2x4GB sticks, respectively) with some spare RAM I have from Dell laptops. These are all DDR3-1333 (or PC3-10600) whereas the original RAM is DDR3-1066 / PC3-8500. I never had problems with putting DDR3-1333 in any Macbook Pros I had prior, this is the first time I'm having issues. The Macbook would just make continuous 1beep cycles and a black screen. Is the MC516LL/A only compatible with the slower DDR3-1066 RAM?
