WoW keeps crashing in main cities with my Crucial DDR4 2666 RAM, will expanding virtual memory work?

Trying to run this game on 8GB of RAM was a total nightmare; it felt like the system was crawling through mud. Whenever I entered Valdrakken, my physical memory hit 99%, and the system started swapping to the disk like crazy, turning the game into a slideshow. I tried closing every single background app, but that only saved about 300MB—completely useless. I finally went into the advanced system settings and manually locked the C-drive page file to a fixed range of 16GB-32GB. When I booted back in, I saw the commit charge hit 22GB, but the out-of-memory crashes completely vanished. I still had some micro-stutters at 16GB, so I had to push it to 32GB and reboot to get it truly smooth. Temps stayed around 40-46℃ with 78ns latency. I exported the error logs from Event Viewer just to be sure, and the crashes are officially gone. It's still a struggle with 8GB, but it's playable now.
