This RAM encryption mechanism must be activated manually in "Performance/Driver Configuration" dialog. RAM encryption comes with a performance overhead (between 5% and 15% depending on the CPU speed) and it disables Windows hibernate. <br> +Moreover, VeraCrypt 1.24 and above provide an additional security mechanism when system encryption is used that makes VeraCrypt erase master keys from RAM when a new device is connected to the PC.
