“Correct RAM I have a Sony Vaio VPCF132FX laptop computer that currently has 4 GB of RAM. I seen that I can upgrade to 8 GB max. However, my question is ... when I Googled VPCF132FX RAM the results showed that I needed PC3-10666 DDR3-1333 204 pin SDRAM SODIMM memory sticks. But when I used Crucial.com scanner, it showed that I needed DDR3 PC3-12800 ... which one is the correct one for my Vaio laptop? Is the PC3-10666 and the PC3-12800 able to be used, if so what is the difference in them?”
