well done.

but 1 question:
how did you get the multiplier to 13?

i tested lots of boards (asus commando (965), asus p5k-e(p35), maximus formula (x38), gigabyte dq6 (x38), striker extreme (680i).

but with none of these i could start with a multiplier of 13. (with 12 it was possible on every board except the commando, but not 13)

any hint?
thanks
