Since my board booted a 930 accidentally at 4730Mhz (215x22) I really had not pushed any higher due to some cooling issues I think it was coincidental that I stopped at 215 bclk, because later attempts to find an upper limit of the bclk in 5Mhz increments I found the board would not post at 216 or even up to 225 have yet to try higher. Not looking good, but I've said that before...
