CPU stays at non turbo frequency

[Fifa987]

Hi, I've been having a little problem lately. Since I have a new motherboard, I noticed that my CPU frequency stays at its non turbo speed even while I used CPU-Z or prime95 to stress it to 100% usage. Even when I attempted to overclock it, it just absolutely ignores the turbo boost speed that I want. I can overclock its non turbo speed how I wish, but the turbo speed simply never works. I am not that skilled in overclocking and have not much experience but I tried everything that came to my mind and everything that I was able to find out online. Nothing worked. I'll be more than happy if anyone helps.

Specs in short:
CPU - i5 2500K (stock speed 3.3 GHz, stock turbo speed 3.7 GHz)
RAM - 12GB 1333 MHz
MB - Sapphire Pure Black P67 Hydra
GPU - Gigabyte GTX 960 4GB
OS - Win 7

Here are my bios settings pictures and some CPU-Z shots along with temperature and other (I hope) useful information.

Turbo speed does not work for all cores under load. Say one core had 100% load and the others had 20% load. Then turbo would enable for that one core, but if all the cores are at 100%, it won't, or if at all only a tiny amount.

It can't turbo if all cores are used; run a single thread instead of 4 and check how fast it runs.

I am sorry, now the pictures should be avalaible. Would you mind taking look at them if it changes your opinion on this matter?

So does it mean that in games, for example, it won't use turbo boost? Anyway when I ran the single threaded benchmarks, it stayed at non turbo speeds.

What happens if you use their settings for the CPU (though the maximum should be lower with your CPU)? http://www.tweaktown.com/reviews/4061/sapphire_pure_black_p67_hydra_motherboard_review/index4.html

rgd1101: I know this. But this is the default settings, isn't it? In BIOS I adjusted it to 1,2,3 and 4 cores turbo multiplier to 40 (therefore it should be 4.0 GHz if bclk is 100 MHz) and non turbo multiplier to 35..But it is stuck at this 3.5 GHz all the time under load. After those settings in BIOS shouldn't it work like it's operating 1.6-3.5 GHz if not under heavy load and 4.0 GHz on all cores under full load? Don't know if I'm right od wrong but i think that with those settings I have, it would kinda make sense.

So you basically set it so it won't go turbo anymore.
I would said forget the turbo(disabled it) and just overclock your cpu with the based mulitplier

Did I? So there's nothing wrong with my CPU or BIOS and it's just me being stupid? 😀
I wanted it to work like pushing the base frequency a bit, like something about 3.5 GHz and while gaming or other CPU intensive applications I wanted it to automatically overclock itself to, for example, 4.0 GHz. Is there a way to make this work?
