Just recently had a PC built for myself and It's everything I've ever wanted, I love it. I don't know a lot about PC builds, but I'm looking to get more RAM. Currently I have 16GB and I want 32. I have 2x Kingston FURY 8GB (1 x 8GB) DDR4-2400 Memory. I'd like to buy two more but all I can find are ones with part # HX424C15FB2/8, and mine are HX424C15FB/8. What is the difference? And will these not work together? Like I said may be a dumb question, just don't want to ruin a good thing here.
