My idea is to increase the speed to 1.6 ghz or 2 ghz to 1.6 ghz because the atoms are.
The only way you can overclock a Brazos is by raising the base frequency. Its already at 100MHz and most cease to function at ~105MHz. That's a gain of 63.5MHz. Really not worth the bother.
I think the biggest problem is related to the other things associated with this bus
