i5 3570k with Maximus V Formula overclocking

Hello Guys,

I have got an i5 3570k with a Maximus V Formula board. I am confused here because this board has so many options. I would like to overclock with my offset instead of having a fixed voltage. Mainly to 4.5Ghz and above but it looks like my chip wont do 4.5Ghz with low volts. It requires 1.34 volts for 4.5Ghz and this is with a fixed overclock. I want offset but I keep getting WHEA errors and the system becomes unstable which clearly indicates that the voltage is not sufficient.

Please can some one help me with this motherboard. What options should I Disable or Enable as this has got too many. I am totally confused here.

I do not recommend offset voltage for overclocking, fixed vcore is best. The only settings that need changing is obviously vcore multiplier and load line calibration or LLC, any power saving features can be left enabled.

But I have heard that Offset overclocking increased the CPU lifespan!! I don't know buy how much though. How long will a CPU last using Manual vs Offset? Any thoughts on this buddy.

For some reason, I too found that having a fixed voltage was much stable and easier for me when compared to offset. Offset always gave me a bit higher voltage even with a negative offset and was still not stable due to WHEA Errors which was not the problem for me while using fixed.

Allright. I followed the guide http://www.overclock.net/t/1291703/ivy-bridge-overclock... and I was able to achieve only 4.4Ghz with a fixed voltage of 1.288 (LLC on ultra high and CPU PLL 1.7v, CPU PLL Overvoltage enabled). Any lower voltage and my CPU gets unstable and I start getting WHEA errors. I also tried 4.5Ghz but unfortunately, that is not stable even at 1.35 volts which is actually too much for Ivy. I guess that I am unlucky and have a bad chip. Max temps on IBT are 78 degrees and Prime 95 temps are 72 degrees max. Its very unfortunate that I got an expensive board but a stupid CPU. I could have got 4.4Ghz even on a cheaper board.

Anyways, will try Offset later after running more stability tests on fixed voltage as I want to be sure about the overclock.

Well, I am not getting any WHEA errors now on the event viewer. I increased the voltage to 1.295 (Negative Offset) + Ultra High LLC + CPU PLL overvoltage enabled and now my CPU is stable with Prime 95 temps around 72 degrees max (2 Hours) and IBT 78 degrees max temps.

Best solution

Ran Prime 95 temps need more than 2 hours .. more long test more get stable .. good job

I just sold my 3570k and bought myself a 3770k and luckily its a good chip. Currently at 4.6Ghz with 1.24 volts.
