memory slot voltages

[patrick_h97]

Hello. I have Asus F550VX - DM 604. i7 7700HQ, 8G RAM, 1TB HDD. I want to upgrade with 8GB ram of memory, but I don't now if I need the 1,2V or 1,3V. Can you help me please, how to check my memory slot voltages? How to check if my memory slot is on 1,2V or 1,3V?

Thank you in advance!

Thank you Mike for your answer, but when I open SPD tab, everything is blank (not completed)...

Curious, some other programs that may show it:

Looks like Crucial says it's 1.2v. http://www.crucial.com/usa/en/compatible-upgrade-for/ASUS/f550vx

I googled "f550vx-dm604t memory" and that's first place it found. That's about all I could find.
