I was able to overclock the q9400 to 3522mhz, i ran LinX (full memory, 50 times), played games almost for two weeks, and it was ROCK-SOLID-STABLE.
My max cpu temp in LinX was 80*, and in games like (GTA IV, BF:BC 2) max temp was 60*.
Here are my bios settings photos :



Maybe you will ask me why my Vcore is so high, because ASRock motherboards have a huge vdroop under load so in idle i have 1,38v, BUT in full load it drops to 1,28v.



Please, can anyone help me with overclocking this cpu higher on this board. 3600 or 3700 is all i need, i tried everything to push it to 3600 but in LinX i have an error.
I tried upping pll to 1,56, vtt to 1,30-1,40, and NB to 1,4-1,44. And i upped my cpu voltage to 1,36 and dram to 2.20v.
