Apple Macbook Pro 2GB 2Rx8 PC3 10600S memory modules Samsung M471B5673FHO 10600S memory is slightly faster than the 8500S., however you will not notice any difference since the speed of the computer is controlled by the motherboard. I offer the 8500S and the 10600S on separate listings. I have found you can use them interchangeable on a Macbook Pro that will accept 8500S. the S is the laptop version of the 8500, same with the 10600 and 10600. 10600/8 = 1333MHz vs 8500/8 = 1066Mhz ; on a desktop the gain is 1~3% assuming the same CAS, bottom-line you will NOT feel any gain or loss from frequency differences. However, going from 2GB to 4GB will yield better performance and increased battery life. 1 year Warranty Yes, DDR3 and PC3 RAM are the same. DDR3 stands for Double Data Rate 3, which is a type of computer memory technology. PC3, on the other hand, refers to the third generation of memory modules compatible with personal computers. Both terms are used interchangeably to describe the same type of RAM.
