Multiplier jumps back to stock speed on my 4790k

[kallisto2]

Hey guys,

i just upgraded my system with a 4790k and a corsair H115i.

Im running it on an msi Z97 Gaming 5.

So now i wanted to OC it in BIOS to 4,4Ghz at 1.2V. When i reboot and look it up in CPU-z it sometimes showed me 4,4Ghz but then at anytime when i run a stress test and look at cpu-z again it is back at stock speed.

What is happening here? Need help!

Thanks!

It would probably be very useful if you can explain in details the steps you took in order to overclock, and the settings affected.

Also, was this cpu ever OCd before? Is it the first time this problem appears?

The CPU is brandnew, got it today, so no OC before.
Well i just opened my BIOS and changed the clockspeed to 4,4Ghz at "Fixed" so all cores have the same speed. I changed CPU Core Voltage to 1,2. F10 save&exit.

Thats all i did so far.

I also tried "OC Genie" to see if the corespeed stays at 4,4Ghz but it also jumped back to stock speed. Temperatures on idle below 30C, at full load about 60C.
