Just like SSDs, RAM degrades over time with write cycles. Its more robust than SSDs and it takes a much longer time for it to happen but it eventually does. The test you mention make a single load on the VRAM so they can run, a game loads and deletes things on the RAM continuously , especially if the amount of RAM is small and if the RAM is old, it can easily fail to change the data in it resulting in the system scrapping everything and shutting down the game.
