Why does League of Legends freeze for a split second during big team fights with Crucial DDR4 8GB?

Whenever a massive team fight breaks out in Summoner's Rift, my screen just freezes for a fraction of a second, which completely kills my combo timing. With a single stick of Crucial DDR4 2666MHz 8GB, the available memory is squeezed between 4.2GB - 5.1GB because of background bloat, forcing Windows to lean heavily on the page file. I tried closing every single Chrome tab, but that only freed up about 300MB, which did absolutely nothing for the stuttering—it was a total waste of time. I eventually dove into Advanced System Settings and manually set the paging file size to a range of 12288MB - 16384MB, moving it specifically to my fastest NVMe partition. Checking Resource Monitor, the hard page faults plummeted from 120 per second to under 15, and my frame time variance tightened from a messy 12-45ms down to a steady 8-14ms. Funnily enough, the first time I did this, the load times actually got worse because of disk fragmentation, so I had to run a defrag before it actually felt snappy. Memory temps stayed around 38℃ - 42℃ with voltage rock steady at 1.2V. After verifying the throughput with a performance analyzer, the resource allocation is finally sticking.
