I need some help to overclock the system i recently built. An overclock from the stock 2.83ghz to anywhere stable between 3.5ghz and 4 ghz would be ideal. I didn't really want to watercool so i have instead installed a mountain of air cooling [7 case fans + 3 HDD fans]. Also my ram is running at 5-5-5-18 timings 800mhz 1.8v but is rated to run at 5-5-5-15 timings 1066mhz 2.2v. Are those faster specs possible with a CPU overclock?
