depends on what your comfortable with. i think most try to stay below 1.60.also if you keep things cool (good airflow) you should be ok w/1.69 i think. im probally not the best person to be asking cause i dont like to go to high on any of the voltages.right now im using pll1.57 and im trying to lower it to 1.5(not comfortable with 1.57)and vtt not really sure but i keep mine below 1.4.but still not 100% sure . please feel free to correct me if wrong.

Sadly, I am not able to boot into Windows without going above the max recommended voltages when going for 4.0Ghz!

I was able to run 24/7 at 4.0Ghz on 1.38v core and 1.1v FSB on my Abit.

With this board I need 1.41v core, 1.5v CPU termination and 1.6900v PLL.

I did do one more max FSB run and was able to hit 550Mhz which is 50Mhz higher then I could hit with the Abit board.

I just wish I had a spar CPU laying around!
