Got my board to do 200FSB, the prob was...

The NF7-S does undervolt the Vcore remember that. It slightly overvolts the mem tho. eg 2.9 is more like 2.97. I have to set 1.825 to get about 1.79-1.81. I added cooling to the mosfet to help regulate the heat on them. You might wanna try remix drivers and modded BIOSes. There's a modded 18 that allows from 5 to 22 mults that have no problems and actually gives better performance. I've seen someone run 10x255 so it works. Remix drivers also help to stablize the system. The reason why I got the NF7-S is because of the 3rd Party support from other overclockers.

Just completed my preliminary 6hr burn in using 5 x 133 @ 1.95v....... Prime95 no longer fails immediatly @ 2.3


Im gonna try running 223 x 10.5 next. *crosses fingers* god I hope this works!
