To date, Intel's mainstream processors haven't supported more than 64GB of RAM. That's not a crisis-inducing problem right now (only demanding pros are likely to notice), but the time when you'll want more is on the horizon. Thankfully, Intel is prepared. The company has confirmed to AnandTech that its desktop 9th-generation Core processors support up to 128GB of DDR4 RAM. Newer, denser memory technology makes that possible, the company said. An update in "a few months' time" will enable the extra headroom.
