i'd wait to hear what others make of it before the flash to f3h jz,if no issues just take my word for it.
Did you clear the CMOS before doing this?
Always clear the CMOS before concluding that the BIOS is bugged. I once had my PCIE frozen at 8x before I didn't clear the CMOS after a flash (unless I went over 100.00 BCLK). Clearing cmos fixed that.

If I can have that bug, who knows what else can happen.
So get that CMOS cleared, enable PLL Overvoltage, and you may find your Multi's working again.
