Question CORSAIR Vengeance LPX 16GB (2 x 8GB)

Dec 23, 2020
recently i have run into the issue of when i go to download certain high capacity games, my RAM in my task manager will slowly build and build from 2gb to 16gb until i black screen and i completely have to restart my pc, at first i thought it was the HDD and it did the same with a new one, and a new GPU, but upon watching the task manager the whole time it has been happening i've seen the RAM slowly build until about an hour into it where it maxes out and everything crashes on the main monitor but the 2nd one will show my background screen and the time of the freeze until i reboot, i tried to run a memory test and it wouldn't reboot from it and i had to restart it again, do you think its time to bust out some new ram? 2016-2021 ram pc specs
