Four dimmers on a dual-channel panel?
Your Z370 board can handle dual-channel memory, so using four 8GB sticks is feasible. Your motherboard only supports dual channels, but you can still get better performance by pairing sticks in two pairs of dual channels. Using two 16GB sticks would also work well and provide more capacity.
It will work, though using two 16GB drives would be simpler and make it easier to upgrade later to 64GB.
