I just got a new i7 3770K for my PC and I'm needing to OC it to keep up with two 7970s. I just installed it and set the multipliers to 45. So its OC to 4.5GHz right now I have been running Prime95 for a little over 45 mins with no crashes. Core voltage is hovering right around 1.32v and temps havent really passed 70c. I have a Noctua NH-D14 cooling it.

So I want to know if this temp and voltage is safe and if you think it would be safe to step it up to 4.6GHz?
Also do I need to change the BCLK at all?

Thanks

EDIT: Vcore is actually 1.316-1.318
 
watch for whea errors in the event log, it can pass prime 95 but fail on applications, for my 3570 i was ok at 1.1V @ 4.3Ghz, in prime and ibt, but in bf3 i'd get whea errors, I see them as a precursor to bsods, which i got. Oddly empire: total war was far harsher than bf3 for those errors. If you get them bump the voltage up by 0.005 and you'll be ok.

Ok thank you I will do that if I start gettin errors. I am at 4.7GHz now vcore 1.33 temps right over 70c. No crashes thus far but is it safe to run at those voltages?

to be 100% honest no one really knows. have a look at these guys. http://www.overclock.net/t/1247413/ivy-bridge-overclocking-guide-with-ln2-guide-at-the-end/0_100 but no one has run one for more than 2-3 months, there was one report of degradation, i.e. needing more and more voltage to maintain speed, or losing speed.

GEEZ 5.3GHz on air and 6.6GHz on water!! Wow that is ridiculous I'd love to know how they got that. My system crashed within 2 minutes running Prime95, AI Suite Temp Monitors, and Internet Explorer at the same time at 4.8GHz
