Which RAM for Samsung NP880Z5E

[Lear Cabrini]

I'm going to upgrade RAM of my PC.
It has 8GB DDR3 embedded and only one slot for expande the ram.
It is currently running in single channel mode.

I want to add one module to have 16GB and also run ram in dual channel mode.

I cannot find any information on which module type I should install. The manual report only DD3 RAM. I asked to Samsung support but they has not been able to help me. They only gave me the phone number of a third-party repair company. A wrong phone number.

Anyway, I read around and it should be SoDimm 204pin PC3-12800 (at 1600MHz).
Anyone can confirm that?
I found in some stores original samsung PC3L-12800. So I'm not sure which voltage version is supported by my PC.

Thanks

Everything I see says the Intel BA92-13138A motherboard supports DDR3 and DDR3L with standard 1.5V and low-voltage 1.35V compatibility.
