Choosing between RAM frequency and timings [duplicate]

I have 2 sets of SAMSUNG 2GB DDR3 RAM

1: 2 x 2GB 2Rx8 PC3-8500S-07-10-F2

2: 2 x 2GB 2Rx8 PC3-10600S-09-10-F2

There 2 main differences: (8500S vs 10600S) and (07 vs 09)

Which set is better to install in my laptop?

Thank you.

If your laptop is able to utilize the 10600 one (i.e. not running it throttled), then pick those. If it supports only up to 8500 (or even less); pick the one with the better timings.

Faster RAM is better in general. If the frequencies are the same, lower timings are preferred, but unless you're an enthusiast, you won't see much difference day-to-day.
