I assume them boards shipped with the correct bios on them to support the i7 6600 chip out of the box ??
[Version 0403 ] -------------------------------------------------- -- bios
Core i7-6700 (3.4GHz, 4C, HT, L3:8M, GT2, 65W, rev.R0) ALL ''0403''
Core i7-6700K (4.0GHz, 4C, HT, L3:8M, GT2, 91W, rev.R0) ALL ''0403''
Core i7-6700T (2.8GHz, 4C, HT, L3:8M, GT2, 35W, rev.R0) ALL ''0403''
I see there were 2 lesser bios on the asus that maybe not support it [don't know ] ????

I guess you could buy a chep skylake chip that's supported under ''ALL'' the listed bios ??
asus list bios for the board but the bios that are listed don't show in the cpu support list like the 2 - 0224 and that 0303 ?? so they left that a mystery I guess ??
don't know maybe risk a cheap skylake 60 buck chip to test with ???
