On a Ryzen system, increasing RAM from 3200 to 4000 MB could still matter even if the GPU is the bottleneck. More RAM helps with memory bandwidth and multitasking, potentially improving performance beyond just the GPU limits.
OCing RAM becomes useful when the GPU is built into the CPU (like an APU).
