Gaming 5 motherboard and i7 4790K

Hi,

  I'm just wondering if there's anyway to stop my cpu frequency changing when I'm gaming? 
The stock clock of my cpu is 4Ghz.  When I start my computer it stays at 4Ghz but when I start Flight Sim X it is constantly changing from as little as 800Mhz to 4Ghz.  I just want my cpu to stay at 4ghz no matter what. Can this be done?

Thanks

Daniel

Hi,

Go into BIOS OC settings, set "Advanced Mode" and there is CPU [some name] (sorry don't remember exactly) and change from "Dynamic" to "Fixed Mode" and see if it helps.
This might also be throttling.  Are temps ok while gaming?

 

[dmangham]

Ok will see and try.  Temps usual whilst gaming go up to a max of 99c.

thank you

These are WAY too high 

Get aftermarket cooler. Remove OC. Now you know it's throttling.. 72C is the max you should aim at.

I have already order a water cooling from corsair to stop that problem.  As for the dynamic to fixed there is nothing that says dynamic. There is a cpu ratio which is set to auto but it won't let me change that.

Ok, cool, AiO's from Corsair are pretty decent.

And to change from Auto, us + and -. But I suggest you don't play any games until you change cooler.

I have changed it to fixed but still the frequency keeps changing from 800mhz to 4.0ghz, I have cpu-z installed and in multiplier it says (8-40)?

 

[Nichrome]

It will say that. Though your temps are not fine and it just seems to throttle down.

 

[dmangham]

is the throttling down due to my cpu being at a high temp?

 

[Nichrome]

Most likely yes. Also it's something to do with C-State which can be disabled in BIOS.
