i penciled the black marked resistor

it was 2.43 default
i penciled it to 2.22 what gave me 1.40 volt
when i pencil it to 2.19 it give me 1.44 volt

it seems a verry good ressistor for a huge voltage range

i get with my gecube 3850 turbo 3 850Mhz@1.40 volt
but i cant get 864 stable...is it the bios bug?
