On the site, the product details mention support for 4xDDR4 dimming and up to 64GB RAM, but also note a dual channel architecture. Your CPU listing shows 2 channels in the specs. This discrepancy might be due to different configurations or updates. Clarify with the manufacturer if you're unsure. Your current setup (16GB RAM, 2666MHz) should work fine with the listed motherboard and CPU.
You can insert the four sticks into the system and it will function properly. It operates in dual channel, covering lanes 1 and 3 together, while lanes 2 and 4 are separate. Ensure the memory matches the specifications of the other devices to prevent problems.
B450 chipset lacks quad channel support. This feature offers no advantage beyond certain workstation applications. The optimal configuration might vary based on the motherboard model and memory type, potentially allowing better performance with just two sticks rather than four.
Four sticks function identically to two on your setup—it depends mainly on available memory. Two sticks are preferable to four because they use less power and allow upgrades to more RAM later. If you currently have two and require additional space, obtain two more identical ones you already possess.
