What frequeny?

Hi all of you,
My laptop is an lenovo B580 with i5 3210m processor . It have a 4Gb memory , made by Hynix .
I can read on this memory "4GB 2Rx8 PC3-12800S-11-11-F3 " and something more literals and digits .
The vendor said me this memory has a 1600 Ghz . Which sequence of literals and digits tell me the frequency?
Many thanks,
