Top best answers to the question «Is cached ram bad»
Cached data in your RAM is marked as low-priority, and it's instantly discarded as soon as the memory is needed for something else. Because this data can be instantly discarded when necessary, there's no disadvantage to using the RAM for cache.
Having cached memory is actually a good thing, unused ram is wasted ram! Windows caches programs/files in memory so that they can be accessed quicker. The longer your computer is on the bigger the cache should get.
