Which RAM config would be better for a Ryzen 3 3900x

futuristicbliss · March 30, 2023

I just bought 2 sticks, 16GB each, of 3200MHz DDR4 CL16 RAM, but I still have my old 2 sticks, 8 GB each, of 2666MHz DDR4 CL16 RAM. The old kit is HyperX Fury, the new kit is Kingston Fury, so I don't think there would be any compatibility issues if I just stick all of them in my mobo (B350 Tomahawk).

So, which config is better - 48GB @ 2666MHz, or 32 GB @ 3200 MHz? I usually have opened a game, Discord and a lot of Firefox tabs, Youtube etc. I don't do any work on this PC, pretty much just gaming.

Do you use more than 32GB of RAM ever? If yes, the 48GB config wins. If no, the 32GB 3200MHz config wins.

More RAM only helps when it's being used, once you have enough so that you're not constantly hitting the page file you want your RAM to be as fast as it can be for best performance.

Just because both kit's are made by Kingston and have the Fury logo on them doesn't mean they're compatible. There are so many things that can make a RAM config not work in this setup that while it'll probably be OK, it's far from guaranteed. Honestly you have about the same shot of the new Fury kit being compatible with the old on as a kit of say TeamGroup or Corsair RAM would.
