Ok, so I downloaded and made my Devcon folder with the text batch file provided online.  It does indeed disable and re-enable my cards.  Now this batch file will do this automatically every time the hash rate drops correct?

Another issue before even calling that a success though... once I run the devcon file it resets everything, but then in cast-xmr the vega's don't get renabled.  They just show they are getting 0/hs.  Do I need another batch file or something to have cast-xmr restart or re-detect the cards?
