FAQ about Acer Nitro VN7-791G-77GW RAM
How much RAM can I put in this laptop?
Maximum is 16GB total. You've got 2 slots to work with, so that's 8GB per slot max.
What type of memory do I need to buy?
You need DDR3 SODIMM modules - the laptop-sized ones, not the bigger desktop sticks. Make sure it's DDR3, not DDR4 or DDR5.
What speed RAM should I get?
1600MHz (also labeled as PC3-12800) is what you want. Faster RAM will work but will just run at 1600MHz anyway, so don't waste money on faster speeds.
Can I mix different RAM sizes?
Yeah, you can do like 4GB + 8GB if you want. Just know that dual channel performance works best with matched pairs (same size and speed).
Do I need to remove the old RAM first?
Depends what's already in there. If both slots are full and you want more capacity, then yes. If there's an empty slot, just add to it.
Will any DDR3 SODIMM work?
As long as it's DDR3 SODIMM at 1600MHz or higher, you should be fine. Lower voltage (1.35V) modules work too, laptop will handle both standard and low voltage.
