Often I'll see people build ridiculous systems with like 64 or 128GB of RAM, which is clearly unnecessary for gaming. However, I did wonder if there would be any speed benefit to buying said more RAM? The main theoretical benefit I could see would be that prefetch could store more information in the RAM and thus there is a higher chance that when something in the OS or an app needs to load, it's prefetched into the RAM and will be accessed from RAM instead of your SSD. Then, if you had say 128GB of RAM, you could theoretically prefetch an entire game into RAM and thus load every file related to a game directly from RAM. That would obviously be far faster than accessing it from an SSD, but in reality does this actually happen?
