Yes, 32GB RAM helps with timeline scrubbing in 4K.

Timeline scrubbing is more about the preview cache than total RAM, but 32GB gives the system enough breathing room to keep more frames ready. If you’re jumping around a timeline with 4K ProRes or h.264 footage, 16GB will choke. 32GB keeps things smooth most of the time.

But RAM alone won’t fix a slow storage drive or a weak GPU. If your source footage lives on a spinning hard drive, scrubbing will stutter regardless. And if you’re using proxies (which you should for 4K), even 16GB might be fine. The real bottleneck is often the video card and the storage speed.

So: 32GB is a solid upgrade from 16GB for 4K editing, especially if you run multiple apps or have a lot of tabs open. Just make sure your SSD and GPU can keep up. Otherwise you’re just feeding a faster engine with bad fuel.
