I suspect the answer is that I won't have a problem, but I would just like to check.

My laptop came with PC3-1333 10600S RAM and I just purchased PC3-1333 10666 RAM. Will the 10666 RAM cause any problems?

Thanks for the help. Any articles that provide more education on the matter are welcome.

It shouldn't cause any problems, they're both the same DDR3-1333 standard. The peak transfer rate of DDR3-1333 modules is 10666 MB/s and some manufacturers report it with full precision while others choose to round it down to 10600 or up to 10700.
