seems that everything i do doesn't make any difference for super-pi stability and i'm quite sure that here the real problem is this crappy BIOS, not settings or something else.
but gigabyte seems more focused on that Touch-BIOS crap and Z68 motherboards instead of make some REAL BIOS for P67 stuff...
plus, with all the gigabyte p67 boards i tryed (2x UD4-B3, 1x UD4-B2 and 1x UD5-B3) there is no way to boot at high BCLK, if i want 104 MHz BCLK several boot are needed (bios 1005 --> bios 1010 --> bios 1015 --> and so on)....
i'm a long time gigabyte fan but this time i'm really pissed off, this is one of the worst motherboard i've ever used.

BTW, thanks for your support, i really appreciate it

I just tested this on my UD5 B3. F3G BIOS, main and backup are both F3G:
Set 104.0 BCLK in BIOS, saved, board powered off after a few seconds, powered back on, booted at 104 BCLK, first try.

Board powers off and on before setting high BCLK, powers off and on again when setting BCLK back low again.
I have NOT tested this with PLL overvoltage.

Are you sure your main and backup matched each other?
Were you using pll overvoltage?
