I know that the L520 allows a maximum memory of 8 GB. Do I have to use each slot to get maximun memory (4 + 4) or can I install a single 8 GB stick into a single slot and leave the other empty? If I can use the 8 + 0 method, does it make any difference as to which slot I install the stick?
Additionally, does it make any difference in speed if I use the PC3-10600 memory or PC-12800 memory?

I'm of the opinion a L520 will support 16GB, at least my T520 and both X220 I have do so. And they're the same generation as yours
Generally speaking it's better to have two sticks for dual channel, 2x 4GB should be better than 1x 8GB. Although the difference may not be so noticeable in normal daily usage.

I may try the 8 GB stick, but I still wonder if the faster RAM (PC3-12800) will increase my speed over the Lenovo recommended PC3 - 10600.
Nope, it won't. Your L520 will "downgrade" to 10600 speeds. But don't worry about that. Those speed gains are only visible in benchmarks. In daily usage you wouldn't even notice...

Hello, this is my first time posting here. I have a L520, and it seems to be running slower with all the stuff I have running. I want to upgrade my memory to try to help this out. Currently I have 2, 2 GB Sticks. By reading this, it seems like I can upgrade my unit. Can you please tell me what kind of Memory I need to purchase and may be a Part Number?

Welcome to the forum!
You need to buy DDR3-10600 or DDR12800 SODIMM RAM, max capacity is 16GB (2x 8GB).
Avoid any no-name brand and any memory that says "Value Select" or "Value RAM" on their product description.
There are way to many part numbers to name them here. You better buy the modules in a Web store of your trust.

Thank You, where would be a good place to purchase this?
I found this on Amazon: 16GB KIT 2 x 8GB SODIMM DDR3 NON-ECC PC3-12800 1600MHz 1600 MHz DDR-3 Ram Memory by CENTERNEX
Would this be good?

I also wouldn't go for that, I'd rather stick to the usual brands, to name a few:
