My World of Warcraft keeps freezing in main cities because my ADATA ValueRAM 4GB DDR4 is maxed out; any way to fix this?

Playing modern WoW on 4GB of RAM is basically a form of self-torture. Loading into Orgrimmar is a complete nightmare. The ADATA ValueRAM DDR4 2666 gets absolutely crushed by the player models, with usage pinned at 95-99%, sending the system into a brutal disk-swapping death loop. I tried closing every single background app, but the game still hovered around 3.8GB on its own—the hardware gap is just too wide. I went into the registry to tweak the memory compression strategy and disabled all the useless Windows telemetry services to scrape together an extra 400MB of breathing room. Task Manager showed the memory pressure drop from 'Critical' to 'Medium.' It still loads slowly, but it doesn't just lock up the whole PC anymore. I actually broke my network driver while stripping the OS, which caused some disconnects, but a quick reinstall fixed it. RAM temps are 42-48℃. It's a struggle, but it's playable.
