Well after looking around in different forums, I' m pretty sure my motherboard can handle 400mhz fsb without raising any voltages. Though, as you recommended me, I will start the system with default stable settings , and then i ll consider slightly overclocking to 3.2Ghz (8 x 400 with ram 1:1 at 400mhz). I believe Zalman 9700 cooler will be able to handle that small overclocking
. Thanks, i ll start working on it soon and i ll post results.
