I have a 32GB (2×16GB) Corsair Vengeance DDR5 kit that I want to overclock. I have overclocked my GPU and CPU before, but I have never tried to overclock RAM. I saw another post where someone reached 6400MHz at CL28. Is it worth doing, and if so, how do I do it safely?

Specs: RX 7900 GRE + R7 7800x3d + B650M AORUS ELITE AX ICE
