My laptop automatically updated to the latest firmware and now it has my memory clocked from 6400 mhz to 6000 mhz when I firmware downgrade to 2.3.1 it runs at 6400 mhz but I am unable to prevent the laptop from auto upgrading to the latest. Posting this so the techs at Dell can look into this as I did get a post memory error on new the firmware no issues with old firmware
