Cant get overclocking to stick in windows (CPU-Z and coretemp)

[Ivar_1]

Hi

I am trying to overclock my CPU for the first time and have spent a long time reading this forum and doing a fair bit of googling, but I cant seem to get it to work.

My system :
Motherboard : P67A-GD65 B3
CPU : I7-2600K
CPU cooler : Noctuna NH-C14
Memory : DHX DDR 1600Mhz 8gb
Bios version : 4.3 (Newest)

Bios settings page one :
Bios settings page two :
Windows settings (Cpu-Z, task manager, hyperpi and core temp) :
I have changed windows power managment to high performance

As you can see, I have changed the CPU ratio in bios to 4Ghz, and it seems to work in the bios as you can see in the top right corner (40x100Mhz). But when I enter windows I get the same results on hyperpi and Geekbench 3 as before I overclocked, and core temp and CPU-Z dosent show any overclocking, even under full load (Windows task manager actually show 4ghz)

Anyone have any idea what iv done wrong?

I did try to enable power technology in bios once and manualy change to max clock on each core, and then cpu-z showed the correct frequency, but the system was very unstable even at 3.4ghz.

What does it chow in CPU-Z in the Multiplier pane (lower left), many of these other BM only show the base rate, they don't show your OC

It says Core speed : 3399Mhz and under that : Multiplier : x34 (16-40).

So you would think it went all the way to 40, but even at 100% load it stops at 34

If showing 40 the multiplier is invoked, try leaving CPU-Z open so you can watch it, and download and run ROG Realbench

Doing the ROG Realbench stress test now, and the multiplier went to x34 and stay there, dosent go any higher.
Realbench only picks up the cpu at 3399mhz - multi:34 - bus 100Mhz.

Do you have the latest BIOS?

Yes I upgraded my bios a few days ago to version 4.3

Have you tried resetting the CMOS, then OCing
