This is great. One of my batch 1 minis ran at 750Mhz for a long time before one board started crapping out and i had to run all three at 550Mhz because of that board, so I'm very happy you put this out. Can't wait for the increased frequencies.
@bakermining76 -- hopefully this works for you! The current image stops at 700, even though the frequencies are completely unlocked... I will update the image as soon as I can get feedback from a couple of users with one that lets you select up to 850 (insane, but it was requested).
