Just read your post after saying my system died at 1,919,976k - Nearly 2GB - with a HD500X (Latest new firmware). Ofline it is stable at 28,784k - no movement for 5 mins. I switch on HD500X and don't touch anything - memory climbs - I haven't even said YES or NO to connecting to the device. Even if I say NO and the SETLISTS are blank memory usage just keeps going up and up and up until Crash.
