Am I mixing different voltage RAM ("1.5v VS "1.5v, 1.35v")? & Mixing different brand ram?

I've been wanting to upgrade my current RAM in my laptop, to a higher speed RAM stick. I only have one slot, so I'd have an extra 4GB 1.5v stick of RAM that was in my laptop. My father has a laptop with two slots for RAM (one slot taken), so I was thinking I would give him my RAM, but, that is if its compatible.

I've been using this software lately, Passmark, and it shows me all of the info about the system. Below is the general info about his RAM:

Samsung M471B5273CH0-YK0, 4GB, DDR3, 1600MHz, CAS-11, 1.5v, 1.35v.

The extra RAM I pulled from my laptop is exactly the same, expect that (1) my RAM is made by Kingston, (2) my RAM says "1.5v," not "1.5v, 1.35v," according to this Passmark software. The Exact model of my RAM is "Kingston ASU1600S11-4G-EDEG."

Does "1.5v" in the "1.5v, 1.35v" mean that the stick of RAM can run fine at 1.5v and 1.35v, so my RAM would be compatible with his current RAM and system?

P.S. I've checked everything about RAM support for his computer, and it supports the my RAM, I'm just not sure about mixing different voltage RAM (if its even a different voltage).

Yea pretty sure it means it can run at 1.35 and 1.5. when i look up the spec sheet for that there is a model that runs only 1.5 and one that can do 1.35 and 1.5. And the thing when you mix voltages is that your laptop only supplies on voltage more of the time. There is a different between DDR3 and DDR3L. The DDR3L is the low voltage one. Some newer laptops only take the Low Voltage one but some take both and some only take the regular one. Try running CPU-Z to look up more data on the RAM. It will tell you what voltage it is running at.
