Help~~Cannot adjust CPU ratio on MSI Z77-GD55 with i5 2500k

[antony11]

CPU: i5 2500K
MB: MSI Z77-GD55

My computer shut down automatically because of Drmos overheating few hours ago.

After that my max CPU ratio can only adjust to 37 and my ram speed can only set at max 1333mhz

Other than that my computer seems absolutely normal.

What is the problem of my compuer, I will never forget to turn on my case fan when playing Skyrim for 10 hours .....

HEEEEELP~~~

I have the same CPU and MB. No problem with overclocking. I can change ration up to 63X or at least is there this option.
BIOS version 1.2B8

Select OC Genie mode or some other mode and then try.

CPU Adjust Ratio is also disabled in your bios. You need to enable that before anything else.

basically I have tried everything, but still didn't fix it.
It is possible to check is there something wrong on my CPU, ram or motherboard..
I don not have any spear parts to test...
