just up the bclk(base clock) to 170 so 170*20=3400 also you did not mention your cpu cooler the stock cooler can hold 3.2-3.5ghz easy but you might think for going aftermarket heatsinks.
If you're trying 3.2Ghz or little more, chances are that you can do it with no Vcore voltage changes. Your system should run cooler, then. Anyway, go for an aftermarket heatsink. Intel's suck event at stock.
thanks guys, just a reminder..it's actually an aftermarket cooler, but i just forgot which one, i think it's from xigmatek (something similar) once again thanks.
yeah, and if you intend to overclock it even more, and use the full power of your system. is recommended to get a good PSU 800~+ . Not saying that yours is bad, im just stating...
@jeyd02: thanks for the advice, but if i only want to oc it to 3.4 or 3.5, 650 is enough yea?
p.s. maybe 3.33ghz
yeah is good enough. and good luck on your overclocking. just make sure that you use the lest amount of voltages.
