And it's great! I was able to save my bios settings from 1704 and reload them into 1902 and my bench tests went up 3% or so. Curiously I'm also running higher clocks, but time will tell if they're actually stable. One thing I noticed is that the ME version did not actually update to the 11.11.65 like it says, but the ME updater for this was added under the BIOS & FIRMWARE tab
