Compatible RAM for my HP laptop?

[Yukoncorny]

Can I use:

Timetec Hynix IC 4GB DDR3L 1600MHz PC3L-12800 Unbuffered Non-ECC 1.35V CL11 2Rx8 Dual Rank 204 Pin SODIMM Laptop Notebook Computer Memory Ram Module Upgrade (Dual Rank 4GB)

In my HP 691740-005 laptop?

Thanks, Ryan

This "HP 691740-005" is not a laptop model, that is a RAM part #

Looks like same speed as the Hynix you listed, so yes it should work if that is the RAM in your laptop now.
