What you're seeing is a cumulative mem. usage of physical mem. & virtual RAM disk, wherein your browsing cache, possibly low/medium memory intensive apps are stored or redirected to store on path of ram disk. If its a lappie, you'd observe some performance hits in some situation(s). In layman's terms, consider RAM disk as a clone of Daemon tools whose job is just to mount disk images(in RAm disk it stores browser cache or similar) temporarily and unmounted immediately after use.I have 8 GB of ram and I started to use AMD Radeon RamDisk and configured for a 4GB V-Memory as it stated, a seperate Disk is been created and it seems, the ram resource has raised up to 71%, but I dont know how its working. Can you elaborate?
If there's confusion, someone expert who uses RAM disk as a daily driver would be more helpful.
