My CPU clocks tank and I lose frames in crowded cities in Horizon Online with Crucial DDR4 2400. Help!

Whenever I hit the main hub city, my frames just dive from 60 down to 25. It's honestly pathetic. The bandwidth on the Crucial DDR4 2400 8GB is totally insufficient for the massive amount of sync data in the Online version. Usage would spike to 98%, triggering aggressive page swapping that left the CPU waiting on data—a complete hardware nightmare. I tried enabling 'High Performance' in the BIOS, but the bandwidth was still the bottleneck, and my temps just went up by 5℃. Total waste of time. I ended up using a pro memory manager to hard-limit all background apps and locked the RAM frequency at 2400 MHz to prevent any downclocking. In CPU-Z stress tests, read speeds stabilized at 15-18 MB/s with frequency jitter under 0.1 MHz. Some of my chat apps stopped working after the limits, but setting them to 'Low Priority' solved that. Temps are 45-51℃. Backed up the config and it's finally playable.
