Software OC is ok for me(stable 3.125ghz at 1.2915v) but i prefer BSEL pin mod on lga775. Voltage control using RMclock. Fan speed using speedfan.
I have a q6600 g0 vid 1.3125v(lapped), stock cooler(lapped), cheap desi cabby, 4 aftermarket fans:1 front inlet, 2 side, 1 rear outlet, mobo: dg33fb.
I have currently done the bsel pin mod taking it to 3ghz and reduced the core voltage to 1.2875v(cpuz tells 1.278v, rest is vdrooped i guess), stress tested using occt, prime95, ibt all for around 24hr at a stretch with fan speed set to 100percent using speedfan ~1600rpm, ibt makes it go to 54c or 55c. Prime95, handbrake, occt only stress it to 48c.
Idle:26,27,26,27
Ps: i use Coretemp.
Pps: If you go offlimits with software oc then just switch off the system powersupply and plug it in after a minute or two and you will be fine, nothing craps itself. don't worry.
