Can I install 1600MHz PC-12800s in a MacBookPro8,1

[h4lp m3]

I have a 13" MBP Early 2011 that came with 4GB of 1067Mhz PC3-8500s memory.

I have heard of people upgrading to 8GB of 1600MHz PC12800s, but Apple website says, "PC3-10600 DDR3 1333 MHz type RAM"

All 2011 MBPs (to my knowledge anyway) will support 1600 MHz RAM. In your case, it would provide a more substantial performance benefit since the integrated GPU of your 13-inch model can take advantage of the faster memory.
