Bios is 1.6 

Any suggestion How to get it to run at 4.4GHz? This is under stress testing. 


Xaltar's description about how Turbo works is right, that is how it has always been with Intel's Turbo 2.0.

Your board's manual shows, in the OC Tweaker screen, an option called CPU OC Fixed Mode. That option is supposed to allow your CPU to run at its maximum Turbo mode on all cores at once. Did you try enabling that option?

But if I recall, during stress testing, the cores may still go below 4.4GHz. That is why you get 4.2GHz, which is actually better than it might be, 4.0GHz.

When you set the CPU multipliers in the UEFI/BIOS, did you select All Cores, and then select 44 for the multiplier?

Finally, whatever result you get, if it is less than 4.4GHz, that is caused by using an H97 board. Only Intel 'Z' chipsets allow true over clocking. The Intel IXTU program will not override that.

Your board is not the problem, except that is how any H97 board will work.

It is the same (or worse) with all non Z97 motherboards. You really need a Z97 board if you want to get the most out of a K class CPU (4790K, 4770k,4690k and 4670k).]]> Fri, 21 Oct 2016 21:29:05 +0000 https://forum.asrock.com/forum_posts.asp?TID=3631&PID=17977&title=h97-anniversary-with-i74790k-stuck-at-x42#17977 <![CDATA[H97 Anniversary with I7-4790k stuck at x42 : That is a pity.

That is a pity.

That isn't how the turbo function works. More active cores = lower multiplier. You will only be able to get 4.4ghz when an application is using a single core, if 2 are active it will drop to 4.3 then 4.2 for 3 cores or more, at least that is the way it works with ASRock boards. It should, without ASRock's tweaks, be as follows:

1 core = 4.4
2 cores = 4.2
3 cores = 4.1
4 cores = 4.0

ASRock's tweaks to the UEFI allow you to run at 4.2 on 4 cores which is 200mhz higher than the CPU is designed to run at stock. In essence you should always refer to the base clock rather than the turbo clock. 4.0 with turbo up to 4.4. This means you are technically overclocked by 200mhz. I have seen a few non-Z boards that at one point allowed you to set the multi to 44 on a 4790k but this was put to an end by intel if memory serves, just like ASRock's non-Z overclocking on your board. A BIOS update (1.50) was released that removed the feature due to intel's wishes. All subsequent updates no longer permit overclocking.

So the only sanctioned way to achieve 4.4ghz across all cores is to upgrade to an Z97 board.

I hope this helps.
