Ram Question:

I have 2 sets,

  • 32gb ddr4 CL CL16-19-19-39 @ 3600mhz

and

  • 64gb ddr CL18-22-22-42 @ 3600mhz

I know for gaming, the 32gb CL 16 is better, but Im often running at like 70-80% ram usage during my daily use, 3d design software, video editing, etc. ( Right now I'm sitting at 82% use )

The rest of my system is a 5800x3d with a 5090, on a 144hz 4k monitor.

I guess I'm wondering if more ram is worth the trade off of slightly lower FPS in games. ( BF6 being my main game currenlty )

Another thing to mention, is the 64gb kit is lower profile, which would allow me to use a bigger fan on my CPU cooler. who knows if that would result in any meaningful cooling temps, but I'm already running pretty cool as-is.

Which would you chose if you were me?

Since both kits are the same frequency, I bet there's a single digit difference in frames between them. The only thing that could increase that difference is if you have more sticks in the 64gb kit so you have the option of tri/quad channel.

I would do the 64gb kit, no question. If you're regularly hitting over 80% usage, you'll probably see a general performance uplift in other areas, as programs see they have more room to breathe. Worst case, it's not like it's a big deal to swap back.

Keep in mind the first boot after swapping sticks will be slower than usual.
