I have just overclocked my i5 3570k to 4.3 GHz. I am running an Asrock z77 extreme 4 mobo with a scythe rasetsu cpu cooler. After an hour of the maximum heat test mode of prime 95, my cpu temps are maxing at 62C. Is this safe?
With this overclock I am using offset mode at -0.035v and my cpu voltage stays at around 1.056v during the test? is this ok? it seems very low
Wow that's one nice chip you got there.
I am also using i5-3570k overclocked to 4.3ghz with an offset of -0.040 and with an additional turbo voltage of +0.004. It's the sweet spot settings for my chip. If I try to lower the offset even further, it's not stable anymore. I'm starting to get WHEA at -0.045 offset. I tried to play around with it by setting it on -0.045 offset and making the additional turbo voltage to +0.008 and +0.016. Still WHEA.
My MOBO is Asrock Pro 3 Z77. On a casual use, vcore ranges from 0.992 to 1.056.
I'm using Cooler Master Hyper 612PWM. My temp doesn't exceed 70 C with an ambient temperature of 27C to 32C. No airconditioning here Lol.
3570k's usually hit around the range your in 4.1-.4.2 with out any real tweaks to the voltage, or just very minor ones. You are lucky 4.3 @ 62C give's you quite a bit of headroom for overclocking I've found that voltages up to 1.4 are pretty safe anything after that I wouldn't recommend for a 24/7, as long as you are under 80C or so after a prime test. the 3570k doesn't draw a whole lot power even at 1.3 - 1.4 V so you can hit high 4's or so safely on a decent all in one loop like the h80 or high end air cooler, I personally hit thermal limitations l at 4.7 ghz @ 1.38 V but for long term stability 4.4 - 4.6 is a really nice OC. Ivy bridge chips are pretty sturdy though, so I wouldn't worry about it degrading or anything like that. You will more than likely want to upgrade to a newer chipset before you can fry them out.
