Any recomendations on getting above 4.5GHz on i7-6700k

[dclems]

Hey guys,
So, first actual attempt at overclocking a new i7-6700k.
I got a stable 4.5GHz overclock at 1.35v, higher than I would like it to be.
I may be just coming to terms with the fact that I lost the silicon lottery.

Wanted to know if there were any suggestions as to what could be holding me back for a stable 4.6 or 4.7. I think at this point its not even about the power I am just mad I can't get stable over 4.5ghz. I can see why people obsess over this haha.

I have tried disabling hyperthreading, played around with some of the powersaving settings, and even tried reducing my ring-ratio a bit but to no avail.

Also tried 1.45v to see if I could get 4.7ghz to work (didn't attempt 4.6ghz now that I think about it. I don't feel comfortable at that high of voltage, just wanted to see if it would do the trick for 4.7ghz, and no luck.

With so many videos of people hitting 4.6 and 4.7 at around 1.3v I am almost a bit disappointed I can't even get mine stable at that speed.

Anyone have any suggestions as to what could be causing the instability?


Not sure if it hurts at all but my power supply isn't amazing, 430w EVGA 80+ rated
MSI z170m mortar motherboard
coolermaster t2 cpu fan (getting great temps actually, staying around 30c)

Thanks!

If you can't even get 4.7GHz at 1.45V I'd say you lost the silicon lottery and shouldn't try for any higher, not worth it.

Sure there are some videos of people hitting 4.6 and 4.7.

There are also videos everywhere of people doing double backflips on a snowboard!

Intel will let you send in your CPU for a new one (for a small fee) if you are unhappy with the performance.

I have only had to do it once and it took a week or so.

Yeah, I don't think I would even want to if I had to run it at that level of power anyways.

I'm curious, is 4.5ghz cap common or did I just really lose the lottery here?

True, even with the exact manufacturing process and identical material, a one per trillion inch spacing difference is enough to make some 6700K able to get over 4.6GHz.

It take whole packages from low ripple PSU, low noise VRM circuity design, and cooling power to break high hertz. Perhaps your parts have been giving their best gone to limit its physical and chemical characteristic.

To satisfy your curiosity you can try liquid nitrogen, SF3D Inflection Point + Mounting LGA 115

The 4.5ghz-4.6ghz is probably the most common on air cooling. The 4.7ghz+ is probably ~20% if the CPUs that are posted about.
