[V2-V3]

Try a 15X multi bu increasing your multi by 1 each reboot until you get to 15.
or by increasing your FSB to 400MHz (1600MHz Effective)
do this by bumping your FSB in these increments:

266MHz-300MHz, 300MHz-333MHz, 333MHz-400MHz.

and I believe your FSB Termination voltage should not go over 1.4v could be as low as 1.3v but on my QX6700 ES if it was above 1.3 it did not like 4000MHz

your CPU could require a different FSB Termination voltage tho.
