CPU Turbo Boost Overclock?

[SnipeYa]

Is it possible to crank up the maximum turbo boost speed of my cpu? I don't want to be overclocked all the time just when under heavy workloads.

I have a Intel i7 6850K, With a corsair H110i AIO but soon to be full loop.

It is possible to overclock with turbo boost that way, but it's less straightforward than with turbo boost disabled. Since the system will dynamically adjust voltages and clocks with turbo boost enabled, it's harder to find and test stable settings.

 

But if you're not overclocking right to the chip's limits, turbo boost OCing works just fine.

 

By the way, not wanting to have it overclocked all the time can also be addressed by power-saving options like C1E, EIST etc. But those are often also disabled when overclocking, for similar reasons as turbo boost.

Turbo doesn't kick in when under heavy workloads instead boosts your clock speed when the current application workload isn't keeping all cores fully busy and pushing right up against the chip's TDP.

Yes, and some people also overclock by going this route. How you achieve it depends on your motherboard's BIOS settings, of course.

I have the Asus X99 Deluxe 2.

From looking at the manual, Asus's boards have their little EZ Mode turned on by default. You can turn it off and switch to a more advanced mode by pressing F7. You can find overclocking settings under the Ai Tweaker.

 

This video by ASUS is for a different motherboard, but it's the same concept, and from what I can tell, they seemed to have changed the turbo boost speed when changing CPU Core Ratio. I'm really hoping this helps, as I don't have an ASUS X99 motherboard and their manual is utter garbage.

I'd recommend disabling turbo and speed stepping while getting your overclock stable with manual voltage.

 

Once you've tested it go back into bios and enable turbo boost and speed stepping (this will have it behave like stock and turbo up to your overclocked)

 

You can also try adaptive voltage. I used a very small offset of 0.005v to ensure it stays stable.

That kind of defeats the purpose.  You can't OC the chip without turbo enabled.  You can however turn off SpeedStep while searching for proper voltage.

You need to read up on Broadwell-E overclocking.  There are a lot of nice features that will help you achieve stable overclocks under different load conditions.  AVX offset, Turbo 3.0, and Asus' ATCT are a few of them. 

 

Broadwell-E can be overclocked in the same manner as any other i7, but the previously mentioned features really help the overclock shine and remain stable/safe for the chip.

 

Here are a couple of great articles to get you started.  There's some really good info in there for both HWE and BWE.

 

If you need more specific help, ask away.  Good luck.

Yes you can oc with turbo enabled, I've done it on my i5. Unless it's different on x99. Fair enough on speed step tho

Yes, what you just said is correct, but the opposite of what you recommended earlier.

I see what I did there. My bad.
