Thinkpax e470 Opencore Catalina Install Issues with Memory

Hi everyome, this is my first time attemping at doing an OpenCore install so dont know too much about this stuff. Every time I boot into the USB, its comes up with the error as I quote "In memory Panic Stackshot Succeeded ** Bytes Trace 7616 ** Attemping system restart...MACH REBOOT". Anyone know how to fix this? My plist & specs are listed below. Thank you
