board is kinda picky for me. on 4-24-2007 bios

I can do 367x9 for 3300mhz on stock volts across the board with mem at 460 with 4:5 divider orthos stable....

but I cant do 400x8 1:1 at the same volts lol

my chip is good at 3200 with 1.2v and 3300 at 1.2375 which is stock vid, mem is good to 1100 at 5-5-5-15 and 2.1v on the p5b deluxe. the chip also didnt mind 400 with 4:5's on the p5b-d either.

I guess I am gonna have to pick it apart. any thoughts ?
