Hello, I have a very simple question. I have 16GB RAM, 2 modules. My exact RAM specs are : 2 x HyperX Fury 8GB DDR4-2666MHz (HX426C15FB/8).
So I have a very simple question, do I have to buy exactly the same RAM or I can upgrade to something similar? I'm asking because I cannot find the exact RAM I have currently on my pc anywhere in my country. The closest thing I have found are these : HyperX Fury Black 16GB DDR4-2666MHz (HX426C16FB2K2/16) . If I put these 2 that are close but not exactly the same as the ones I already have, would it be a problem or it wouldn't work properly? And if they are not compatible, the only solution is to buy entirely new ones, either 4 x 8 or 2 x 16 to get to 32GB? If it helps, my other PC specs are :

Usually a new set the best bet.
I have found a 4GB RAM with exactly the same code ( HX426C15FB) and the same mhz ( 2666). Is it worth upgrading with 2 of them, and going for a total of 24GB? And will the 2 x HyperX Fury 8GB DDR4-2666MHz (HX426C15FB/8) I already have, work properly if I add 2 x HyperX Fury 4GB DDR4-2666MHz (HX426C15FB/4) ?

I have worked with mixed memory on many builds and never ran into any issues
my current pc also runs on 3 different types of ddr3 and i have 0 issues (32gb also)

That being said for max performance it is always better to have a "set" of ram, but the difference is next to none
If you have different speeds, the pc will work at the lowest ram speed

so i wouldn't worry, just match the speed
