Overclock not sticking? 6800k + asus x99 aii

[SubLimation7]

So I've been running my cpu stock, but today I decided to OC a bit.  All I did was disable turbo, and change core 0 and 1 multiplier to 42 (which bios said should be 4.2ghz) and left all the other cores at x38.

When I get into windows, it shows the cpu wont go over its stock 3.4 ghz.  Yet in intel XTU it shows the multiplier for all my cores is set to 42 yet still only gets up to 3.4ghz.  This confuses me even more, the fact that its showing different settings then I chose, and the fact its showing high multiplier at stock speed.  Never had an issue like this before... but it is my first time ocing intel since 3570k.

 

Thanks in advance!

 

Update:  Just noticed in XTU it shows my non turbo multiplier is still at 34x.  Time to go find where in Bios the regular multiplier is lol...

Windows does not read X99 speeds properly i have the same issue i am yet to find a solution but i don't care really, also with x99 you are overclocking the turbo speed and since you have disabled that it is resulted in just stock speeds.

you disabled turbo which is what is being used for overclocking, if you disable turbo boost you won't be able to overclock.

You have only set 2 cores to 4.2 Windows is dumb and will see that most of the cores are still at stock speed and will report that. My 6850k is running at 4.4Ghz and Windows reports 4.2Ghz, use somthing like CPU-Z to get accurate clock speeds.

 

Interestingly if you manage to get 4.3Ghz you will match the single core IPC of a I7-6700K (current best at single core) so it will be a 6700k with more cores.

In stress tests the first 2 cores are still running super chilly, so I don't think the OC stuck.  And Cryptonite, are you saying the only way to overclock this chip is using turbo boost?  I couldn't find anything in bios on overclocking non-turbo values.

yes, when you set the clock speeds you are setting the turbo boost frequencies.

You're only really boosting the 4.2GHz when the load is 2 cores or smaller. When there's anything larger the multi kicks down to stock. 

 

Just clock them all to 4.2GHz and reap the gains. 

 

And task manager sucks for reporting speed. Use CPU-Z.

That's lame.. I wanted to get rid of turbo for better voltage control and just leave speedstep on.

Well I also used XTU and OCCT, but look in XTU, it shows every single core at 42x, yet showing 3.4ghz speed.

 

Also, in CPU-Z you can watch different cores change their multipliers independently based on load, so are you sure about the multi throttling?

what's wrong with the voltage control? 

also why just change 2 cores frequency??

XTU is a bit weird in places. It should be showing it correctly.

 

When you've a 2 core load you're boosting to 4.2GHz. When it's anything more the whole thing should be boosting to whatever the stock multi is. When you've more cores completing a task you can bring the clock speed down to save a bit on power and heat, at least that's how Intel thinks. Certainly not how the enthusiast sector thinks. 

 

Why you bother with per core overclocking is beyond me. Just set the turbo multi to 42 and be done with it. Stop making it hard for yourself.

Well the issue apparently was that there is no way to overclock these chips without using turbo.  I simply turned turbo back on and its working now.  I'll probably up 4 cores to 42 and leave 2 at 38, if I notice them throttling down to 3.8 during gaming I'll just OC all 6 cores.  I still don't see what you mean by everything going to stock multi, see screenshot from cpuz.  But do notice how much cooler my core 0 and 1 run in the screenshots, that's one of the main reasons I wanted to OC them.  Even running at 4.2ghz core 1 is still pretty chilly.

Just some more real world examples...

As you all know CPUZ shows core multiplier and speed in real time.

The screenshot of bf1 looks horrible lol, but serves the purpose nonetheless.

If someone knows something I don't please let me know, but it seems that ocing a couple of cores does indeed work fine on this particular platform.
