Right now I am stable at 3.8, using a 21 multi ( from turbo being one ). I wanted to turn off turbo and drop down to 20 so I could use my DVID. The issue is that I need a big big jump in voltage to even boot going from 181x21 vs 191x20. Anyone run into an issue like this? I am using a ga-x58-ud5 with the latest bios.
