Hello,

My computer setup:

Motherboard: Gigabyte Z77-DS3H rev 1.1
CPU: i5-3570K CPU
VGA: Gigabyte GTX 650 Ti 2GB
Current BIOS version: F10f

So yesterday I decided to overclock my CPU. First of all i tried to use EasyTune6. I made a change in quick boost, but after the restart it didn't change anything. So then I went into BIOS (it was version F10f by this time), tried to increase the CPU Clock ratio from 34 to 40, saved and after a restart entered the BIOS to check the new CPU values, but nothing changed, it used CPU Clock ratio 34.

I read some forums and decided to get back to BIOS version F9, and try that way. It was the same, it didn't save my clock ratio changes. So i decided to update it back to F10f. Then I went into BIOS, changed the clock ratio again and the problem started here. After i saved and quit from BIOS, the system stops on boot splash screen, and it doesn't answer to any key press.

As far as I know CPU clock ratio 40 shouldn't be problem for an i5-3570K... Everything else in BIOS I left on default values (Auto).

So what do you suggest, how to revive my computer from death?
 
Solution
I would pull the battery and reset the CMOS. Check your manual for specific directions for you motherboard. It may be necessary to reflash your BIOS.

I got back my PC after the battery remove, but now I'm at my previous state: I can't overwrite the CPU clock ratio. Whenever I try to add a value in UEFI it doesn't change after the save... Any suggestion?
 
The Gigabyte board is dual Bios. One is permanently downclocked. Switch to the other bios. You can do this via uefi.

The problem is: manual is not detailed at all. I couldn't find anything about switching between dual BIOSes, neither your quote says anything useful (I guess it's from official Gigabyte's website).

I found a solution though: Flashed back an older version of BIOS (F9), then Flashed back the newer one F10f, and now overclocking is working in UEFI.

I guess my problem was in first hand: I used @Bios to flash the BIOS. As I read through forums I found out it was a bad choice :) This time I used Q-Flash, overclocking is working, and I don't stuck on BIOS splash screen.

So moral of the story: Never use @Bios!

Thanks for advices guys, i really appreciate your quick responses.
