Max Vcore for Mobile Barton in A7N8X?

I was wondering what the max Vcore is for the mobile Bartons in the A7N8X BIOS? I know that it is usually recognized as an "unknown CPU", so I don't know if it will default to the max Thouroughbred or Barton Vcore. If it will let you select the max Barton Vcore (1.85V) that would obviously be a lot better (because I read that it's less if it detects a Thouroughbred)!! Anyone know?
