Hello, as the title of this thread says, can someone help me decide what memory I need to buy?

I just bought a laptop, Asus R510JK-DM087H, because it was at a good price for what it has, as far as I understand, except for memory, it has only 4 GB, but I thought "ok, I can buy it in discount and then buy some more RAM".

But, it's more difficult than I thought.

I see the box the computer came in, and it says DDR3L 1600 4Gb.
I see the description at the site I bought it and it says DDR3 1600 4Gb, and that it has a free slot where I can add up to 4Gb more (max 8 GB supported).
I use CPU-Z, adn it says DDR3, and that my model is X550JK.
I use the Crucial system scanner, and it says that my laptop model is X450LB, and that I can buy an 8 Gb RAM to upgrade my memory.
I write to the people in Crucial, and they answer that my model (R510JK) is equivalent to X450LB, that I can only add 4 more Gb...and they attach a link to the suggested purchase..which is 8 Gb..?
I try to use the Corsair web page to decide, but my laptop just doesn't appear there (not R510JK, not X550JK, not X450LB).
I write to Asus. But they don't answer.
I open the memory panel in my laptop, but the soldered Memory is kind of hidden, and I can't see no sticker with the specs.
So..can anyone help me? here is where I found this laptop:

and so far, with everything I've done, I think I'm supposed to buy a single 4GB stick, DDR3 1600 Mhz SO-DIMM 204 pins PC3-12800 unbuffered non-ECC 1,35v (which would make it a DDR3L..? did I get it right?).
I've searched a little about all those things, and read about ECC, registered memory, DDR3L, what voltage would be better to buy (if you can) and some other stuff.
But I can't just go and buy a memory, even if I think that's the one I'm supposed to get, only to find out it doesn't work with my laptop, because I just can't go and buy another one then.

So before doing that, I thought I could ask here for help.

So thank you very much to anyone who can give me a hand with my problem.

Popularity does not equate to reliability. A life time warranty does not really mean much when it comes to reliability either. It just means should the RAM fail, the manufacturer will replace it.

Both Corsair and Crucial likely uses the same RAM chips. Since Crucial is a subsidiary of Micron, it is extremely likely they use RAM chips manufactured by Micron. Corsair likely uses Micron RAM as well, but they source from many manufacturers so production batches can use RAM chip from different sources. That generally does not mean Corsair RAM...

Ok.. just to be clear.. I got it right only when I say it can be complicated, or also when I say that that's the memory I need to buy? And if so, would you mind explaining to me how to be sure that's the one?

this is the right one http://www.newegg.com/Product/Product.aspx?Item=N82E16820233582

I see for laptop 1600Mhz ram on Newegg

1.35V(138)
1.4V(2)
1.5V(89)

many are 1.5V.

the thread opener can have an Internet trip, and see how popular Corsair is among gamers, and how it is Crucial, then decide.
Reliable? Any decent branded RAM comes with lifetime warranty.

That generally does not mean Corsair RAM is better or worse than Crucial RAM. However, the Crucial RAM I linked is less expensive than the Corsair RAM.

While the Cas Latency for the Crucial RAM is not listed, it is very likely CAS 11 since that is the slowest I have seen and it matches Corsair. It also sells for $6 less.

Thanks everyone for your help! got to say, it's the first time I ask something online myself, I really hope this post can also help others with the same or similar doubts, just like it usually happens to me with other posts as I google something.
