Hello, i recently just overclocked my gigabyte ds3 mobo together with a core 2 duo e6400. Just wanna ask some quick questions.

These are the settings i used for the overclock.

CPU Clock Ratio : 8x
CPU Host Frequency : 400
PCI Express Frequency : 100mhz
System Memory Multiplier at 2.00
DRAM Timing at 5-5-5-12

DDR2 Overvoltage Control +0.2V (2.0V) ----------> What does this do?
FSB OverVoltage at Normal -------------------------> I set this at the normal value
MCH Voltage 0.1V at Normal ------------------------> I set this at the normal value

CPU Voltage at 1.22500V ----------------------------> The normal value is suppose to be 1.25, but i reduced the voltage to 1.225.. can anot?

Are the settings ok to use?

Thank you everyone for your advice, the website you have provide helped me very significantly!
