Z77-DS3H, i5-3570K hangs on BIOS splash screen


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?

  1. Best answer
    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.
  2. I'm stucked on BIOS splash screen right now, nothing works. All I can do power on/off. I will try to reset the CMOS, I hope that will help.
  3. Gota switch bios bitton on the motherboard? Read your mobo manual. I'd also use the mobo uefi for overclocking etc rather than any 3rd party software.
  4. 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?
  5. I would use the Gigabyte UEFI to overclock the CPU. Check your manual for directions. That motherboard has a dual BIOS so that may be introducing some confusion as well.
  6. The Gigabyte board is dual Bios. One is permanently downclocked. Switch to the other bios. You can do this via uefi.

    "At the heart of this exciting 3D BIOS technology is a pair of physical BIOS ROMs containing GIGABYTE's exclusive in-house designed UEFI BIOS technology. With a superior graphical interface capable of 32-bit color imaging and fluid user-friendly mouse navigation, UEFI DualBIOS™ makes BIOS configuration a new and exciting experience for novice and experienced users alike. UEFI BIOS also brings native support for large hard drives on 64-bit operating systems."

    "Advanced mode provides a more comprehensive UEFI BIOS environment that is designed specifically for overclockers and power users who want maximum control over their PC's hardware. GIGABTYE's signature M.I.T. tuning technology can be found alongside fully configurable parameters for GIGABTE's all new digital 3D Power engine. In short, advanced mode combines the signature GIGABYTE BIOS expertise you've come to expect, wrapped a slick, new and optimized graphical UEFI interface."
  7. 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.

    "If your system supports Intel Hyper-Threading technology, please kindly disable the function in the BIOS." - so not with a 3570k
