My i5 4690 (non K) is not reaching 3.9 GHz!

Recommended Posts

Posted · Original PosterOP

Hi guys!

I have an i5 4690 (non k) and on every game I play my CPU doesn't reach the its maximum ratio, that is 3.9 GHz. It always on 3.7Ghz.

I'm no expert but, during gaming/under load, it isn't supposed to use everything it have?

I did check everything on the BIOS and I believe everything is set correctly.

P.S. Every time I changed the CPU Clock Ratio to ON (on the first picture) and change tabs it goes back to OFF, that's only a 'glitch' or it's something wrong?

Can anyone tell me how do I set the core to stay at 3.9?!

 

Thank you!

My specs:

  • i54690
  • GTX1070
  • 16 GB DDR3 @ 1600Mhz
  • H97M

It'll never be at 3.9ghz normally because that is the Single core Turbo boost, the official All cores turbo boost is 3.7ghz which is what you're seeing meaning your locked CPU is working Exactly as it's supposed to.

Is not a k series CPU, so overclocking is out the question.

 

This leaves with the boost types intel uses which makes fluctuating CPU clock completely normal. Also thst is probably 3,9ghz one core boost which you will pretty much only see in single core cinebench

So sorry, but why they would boost only one core to 3.9? Why not all of them?

 

Also, using MSI Afterburner showing all cores, every one of them is at 3,7 under load. So, it isnt supposed to one of them be at 3.9?

It will boost to 3.9 GHz only in very specific single core loads and it most likely won't be sustained for long. Single core turbo is just like Intel's TDP - the only purpose it serves is marketing.

Because they have to meet the TDP rating, more frequency means the need for more volts meaning hotter and more power consuming chip, Intel always says: Turbo Boost "UP" to 3.9ghz, see they have a little 'play' there.

 

It's not because this is like said Single core, meaning only 1 core in function, since you'll have a lower energy use with only a single core being active you can raise the frequency and stay within TDP rating.

That's just how Intel turbo boost works.

They set the boost speed to only one core to keep the chip within it's tdp rating. They also do this to segment their lineup of processors, 4430, 4460, 4590, 4690, etc. I personally don't agree with this blatant stagnation of the skus, I much prefer AMDs approach of having nearly every processor in their lineup unlocked and overclockable, but Intel has always been this way, even now with their Coffee Lake processors they have multiple skus of i3s, i5s, and i7s, which only vary about 100-200 MHz between each other.
