FAQ about Acer Nitro VN7-791G-78X5 RAM
How much RAM can I put in my VN7-791G-78X5?
Maximum is 16GB total. You've got 2 slots to work with, so that's 8GB per slot if you want to max it out.
What kind of memory sticks do I need for this laptop?
You need DDR3 SODIMMs - those are the smaller laptop memory sticks, not the big desktop ones. Make sure they're DDR3, not DDR4 or anything else.
What speed RAM should I get?
1600MHz is what you want. Sometimes you'll see it listed as PC3-12800 - same thing, just different way of saying it.
Can I mix different RAM sizes?
Yeah, you can do like 4GB + 8GB if you want. But matching sizes (like 8GB + 8GB) usually works better for performance.
Do I need to replace both sticks or can I just add one?
Depends what's already in there. If you've got one slot empty, just pop in another stick. If both slots are full with smaller sticks, you'll need to replace one or both to upgrade.
Will faster RAM like 1866MHz work?
It'll probably work but just run at 1600MHz anyway. The laptop will downclock it to match what it supports, so you're basically paying extra for nothing.
