Memory compatibility question

[bnichols024]

Hello all,

I am looking to upgrade the memory on my laptop and I wanted to see if these two sticks are compatible. I thought they were identical, until I looked a little closer. Here's what they read:

SK Hynix 4GB 1Rx8 PC3L - 12800S - 11-13-B4
SK Hynix 4GB 2Rx8 PC3L - 12800S - 11-12-F3

Are these two going to work together? I'm entirely sure of what the last 3 segments mean.

The last segment is the timings of the memory. There doesn't seem to be a large variance so it should be compatible. Generally, the BIOS will automatically choose the best configuration for the system and this ram should be fine.
