hi all

i got a problem with the multiplier management of my P5B Dlx...

all unlocked CPU can only get 11 multi max...
2 old X6800 B2 i've tested, and now my QX6850 got same problem

unable to OC under cascade with QX and 11 multi
i've try some different BIOS without success
someone got same problem ?

NB : already seen 13 multi with one P5B Dlx : http://beforeoverclock.com/images/X6800CPUZ@5512.png
