Question New cpu,ram and motherboard no performance improvment in video editing?

[tdr12]

Recently i bought a ryzen 5 3600,24 gb ram and a new motherboard for video editing in adobe after effects,premiere pro.but i dont see any improvement in performance,the rendering time its almost the same,having more layers/effects causes lag in previews or freezes.I didnt reinstall the windows after changing the specs.Here are my old and new specs
any help??

OLD:
CPU: i3 4160
GPU:GTX 1060 3gb
RAM:12GB ddr3
MOTHERBOARD:asus h81m-k

NEW:
CPU:ryzen 5 3600
GPU:GTX 1060 3GB
RAM:24GB DDR4
MOTHERBOARD:Asus B450m a II

First thing to do is properly install a fresh copy of Windows rather than cutting corners.

24gb is a strange size.
What is the make/model and speed of the DDR4 ram?
Is it on the motherboard ram QVL list?

What does cpu-Z say you have?
I suspect that the ram is defaulting to single channel mode which gimps your cpu performance.
