Guys I was messing about the other day & not paying attention when trying to update the backup bios. I ended up swaping bios's!!! Anyway I figured it out ALT + F12 once = update backup ALT + F12 3 times = swap Bios. I now have F6 on one & F6d on the other & can just switch back & forth

Level 1 voltage in F6 looks like it has been eased back a bit but cant 100% tell as I can only run 4.9 without int pll so maybe the chip isnt loading as much Level 2 now works but spikes voltage bigtime dont use it.
