Hello, I have a (MSI gf63 thin 10scxr) windows 10 it currently has 8 GB of RAM . I have 2 broken unused laptops, and found some ram one is 2 GB and one is 4 GB they look different and I am going to use the one that fits I am going to post a pic. Will it shorten the life of the laptop?
Mixing RAM is a tricky business. You can of course just add the sticks and see if anything breaks—if it does, just remove it again. But generally, mixing different types can cause weird glitches later—but shouldn't shorten the life as far as I know.
