Default amazing retro FSB overclock on old Prescott P4 3400MHz 478 Pin uPGA

As soon as I unlocked the multiplier from 17x to 14x it opened up a whole
new world for this machine..
couldn't run the memory at its stock setting though at these speeds, as it
wouldn't post.
I'll sacrifice the mem bandwith for higher FSB any day!
