Is a matched set of four RAM sticks needed when going to 32GB in a W540?

The W540 I just got has two 8GB Samsung sticks of RAM installed-guessing the original. DDR3L-1600. My head says I do not need 32GB for email, surfing, the How-to YouTube video, and some light photo editing-but my heart says why not see how quickly and smoothly it runs (I've already done the Samsung 860 EVO SSD). My question is, do all four sticks need to be the same, or could there be two pairs of matching sticks as long as all four had the same specs? If two pair of matched sticks would work-says two Crucial in addition to the two Samsung, how should they oriented? The two sticks in there now are in slots 2 and 3 according to CPU-Z. TIA

Basically any stick that works will do.
Having 2 matched pairs would be nice but is not really needed.
Most important is that all sticks have the same speed, brand is of less importance, but avoid so-called Value-RAM.

Thanks. That's kind of what I thought. The next question is, does orientation matter? Should one matched pair be in slots 1 and 2, and the other in slots 3 and 4? Or doesn't it matter? TIA

The same applies to W510/W520/W530/W540/W541
