So yea you can go up to 8gb on each channel but going back to your original question I'd get the 2x8gb kit instead of 4x4 for better (a little bit) performance.I think it's called M5A78L/USB3 by ASUS. It's not very modern but it says max 32 GB so I'm not sure. This is the site for it: https://www.asus.com/Motherboards/M5A78LUSB3/
