No, it does not fully utilize all four memory slots.

No, Ryzen actually gains advantages when memory modules are fully populated.
It misses the benefits of quad-channel memory like a Threadripper would. What I’m talking about is that with four DIMMs you end up with just two channels, making 4x4GB behave like 2x8GB under normal conditions. However, when all slots are filled, speed issues can arise. For these reasons—no real performance gain and possible speed limits—I usually avoid using four DIMMs of memory.
