Which settings to OC 6700K to 4.6 GHz?

King Mustard · 5 Oct 2016 at 16:14

My hardware:

MSI Z170A Gaming Pro Carbon
Intel Core-i7 6700K (at stock 4.2 GHz)
Corsair Hydro H100i v2, H110i or H115i AiO liquid cooler (purchasing soon)

In MSI's Command Center, I can turn on Game Boost, which OC's the CPU to 4.4 GHz.

In reviews for the motherboard, they state they can reach 4.9 GHz with the 6700K.

I would be more than happy with 4.6 GHz.

What should I manually change, in order to reach a 4.6 GHz overclock?

You'll need to enable the advanced settings i assume as you need to control the vcore and other settings to stop temps getting to high. anyway; the OC also depends on your chip too

I'm guessing most 6700K chips can go to 4.6 GHz if all the reviewers are hitting 4.8 GHz+?

Set core 1.39v
Up multi to 4.6
Check stability and temps, try dropping vcore and test in steps.

what he said; keep an eye on temps and make sure they don't go too high. use realbench or something simular to stress.

Do not use software for OC! Go into BIOS and do it there, properly.

Mine reaches 4.8GHz with 1.35V. But 5GHz already wants 1.45V.

There are so many guides on this, even on here... Do it in BIOS, its dead easy. Apply a core ratio of 46 and then voltage test starting at something like 1.3v, increase if unstable by small steps 0.02 or decrease if stable until unstable.

When you find the sweet spot best practice is to switch to adaptive and add a small buffer of 0.02 to allow for a bit of variation. But yeah loads of guides on it...

King Mustard I have a similar board to yours. I tnot exact but it from the same company. FIrst thing you need to do is lower the SA voltage and IO voltage. MSI for some reason like to hammer those. Hopefully you should benefit from slightly lower temps but more importantly the lifespan of your cpu will thank you.

I've set the Core Ratio to 46.

1.300v - System freeze within 10 seconds of OCCT.
1.350v - System freeze within 10 seconds of OCCT.
1.370v - Two cores fail during Prime95
1.410v - One core fails during Prime95

Any ideas?

Can you give me some more information on this, please?

What PSU are you using?

EVGA SuperNOVA NEX 750W.

I had problems with OC when I used my old Corsair CX750M PSU. Although my issue, was that 4.8GHz was somewhat stable, but 5GHz could not be achieved for stable running. And anything above stock clocks was causing CPU and PSU to whine, scream, you name it.
As soon as I bought Platinum PSU (though Gold would've been sufficient), 5GHz was 24h stress test stable.

Maybe your PSU is looking towards being replaced?
