On my P67A-UD3P it does it too when Internal PLL overvoltage is enabled! I was wondering if there were others with this issue.

I'm glad I just found this post via Google. I just RMA'ed my 2nd Z68X UD3H B3. Both times I got stuck in "boot loop" I had restarted my computer via Windows 7, not the reset button. Once, I was messing around with their EasyTune6 software and the next time I had restarted after letting the PC run all day downloading stuff. I just get stuck at the Gigabyte screen and then endless reboots until I flip the PSU switch. I had already tried CMOS clears and battery removals and disconnecting everything. The first board lasted 3 days and the replacement lasted a little over 2 weeks.

Sometimes it will work for a week other times boot loop, I can play hours and hours of BF3 and skyrim, do lots of photography. It's 10+hrs prime 95 stable and many many runs of Intel Burn test at both medium and high. Yet sometimes when you boot the system it will hit a boot loop, and keep getting to the bios logo and turning off, then turning back on again. You have to leave the power cable out for a bit, then reboot while pressing DEL to get to the bios setting's screen, to reset back to 4.6GHZ.

However If i then go back to the bios and set to 4.7GHZ with my above settings it will work perfectly again, any advice?

I think the boot loop is a problem with the older revisions of gigabyte borads, i heard with the new ones they are fixed especially when updated to the latest BIOS.

I just wanna say thanks to GldRush98 and his find on pg.44. I encountered the boot loop problem as well when changing the voltage for OC, and it was one of those boot loops you pretty much give up on and RMA. Everytime i unplugged it and plugged it back in and powered up it would go immediately to the boot loop, and the few times I saw the bios screen it would restart before i could even hit delete. I was trying every method until i tried this:

Update: I was able to get my system booted from what seemed like a permanent boot loop!
I found this post over at TweakTown that SAVED me!!!

It is possible to make the BIOS Auto-Recovery kick in (Dual BIOS) and re-flash the MAIN BIOS with the contents of the BACKUP BIOS.

This is a simple and easy method for anyone to try before having to resort to other more difficult methods, or a RMA.

1. Shut off the power supply using the switch on the back of the PSU, wait 10-15 seconds.
2. Press and hold the case Power On swtich, then while still holding turn on the power supply from the switch on the rear.
3. Still holding the case power on switch, the board will start, once it does release the case power on switch and shut off the power supply via the switch on the read of the unit. (Do the latter two parts as quickly as you can once the board starts)
4. The board will shut down.
5. Turn the power supply back on using the switch on the rear of the unit.
6. Turn on the motherboard by pressing the case power on button.

Once the board starts this time you should see the Gigabyte splash screen, or POST page, then the Auto-Recovery from Dual BIOS will kick in. You will see a checksum error, and then recovery from BACKUP BIOS will begin. Once it is done reboot your machine and enter the BIOS and load optimized defaults then save/apply/reboot back to BIOS.

Now you are done, and will be using whatever BIOS was in your BACKUP BIOS, From there you can attempt whatever you were previously trying, or update your BIOS to the latest version.
I had to try it a couple times but it did eventually start up and kick to a plain black screen with white text saying it was copying the backup bios to the main bios! It finished and I rebooted and I was able to get in to the now reverted main bios with older version on it!!
I then downloaded the latest BIOS (F7 at the time of this writing) and I flashed it inside QFlash, which I could also finally get in to! After I flashed the F7 to main I was able to get in and configure the BIOS. I booted windows and then rebooted about 5 times to make sure everything was good.
I then hooked up a PS/2 keyboard so I could ALT+F12 on boot and copy the Main BIOS to the Backup BIOS. It finished up, so now I have the latest F7 BIOS in Main and Backup. Oh thank science.

For now I am going to leave the BIOS settings alone and keep this board since I have it working again (I really don't want to switch, especially since I have Win7 already activated on this board!).

Good luck to those of you out there battling this issue. I know how helpless you feel

I switched off the power supply, held the on switch down and switched the power supply back on. It booted up, then shut down. After letting go of the on switch, i hit it again and was able to get into the bios without it looping anymore. From there I was able to re-flash the bios since it was corrupted from the infinite amount of boot loops. Now everything's up and running again, just gotta be careful with the overclocking and reset switch.

And for people still on the fence about this board? Don't do it. I only did because of the Micro Center deal where you get the board and an i5-2500k for $280. That's a good deal, but with all the trouble i've had to go though with this board so far, i'd glady spend more money on something more reliable. Especially now since that deal's over, lol.

After experiencing this problem , I googled for solutions.
Seems I'm screwed wink.gif

I had the Gigabyte GA-Z68X-UD3H-B3 S1155 board for 4 weeks, never experienced any problems.
Last night I went to sleep while my computer was still on, I woke up this morning from the fans constantly spinning up.

(My CPU is a Intel I5 2500k, overclocked to 4,6 GHz)

So I went to check it out, removing all drives first, still it existed. Played with the RAM sticks, nothing.
I tried clearing the CMOS, nothing.
Eventually I had it on a cardboard box with JUST the cpu in it (and cooler ofcourse ;-) ) It was still in the loop.

To be clear, this is the loop where it starts up for 1 second, then shuts down, starts up again for 1 second , shuts down --> repeat forever.

The weird thing is, my computer was running, somewhere it must have rebooted by itself and got into this loop.

I delivered the board + power supply back to the store. The power supply just to be sure.

Tomorrow i'll hear about the problem, and they can keep the board, I'm going to any other brand then this after reading all the problems with it.
It's unacceptable.

God knows if my system was in this loop for several hours, and i hope it didn't damage or destroy any of my other components while rebooting a gazillion times.

the tips on here seem helpfull, but i'm not going to risk it. It should always work and I don't want to much hassle for just turning my computer on.

Good luck to other people with the same issues, Gigabyte won't see my money anymore.

((((UPDATE)))) COLD BOOT BIOS FIX!!

I've been in discussion with Gigabyte support for awhile now sharing my settings and what's been going on in this thread and Gigabyte have released a NEW beta bios F7B!. Although it does say Improve ISRT+MARVELL RAID compatibility, Gigabyte have told me that This Beta BIOS attached via support is to fix the cold boot issue.

This board is a real pain in the backside to work with after a bios flash, the same thing happened previously. You'd flash the bios, reboot the system and it would constantly get stuck at the bios logo and shut itself off. Clear the cmos then it would finally get to the bios so you can set your system settings up. After setting the default settings ( not overclocked ) and click save and exit it would save and the system would shut down and power back up again before going into a logo loop requiring another clear csmos then it works perfectly.

What RAM are you using?

I've seen some people having problems with boot loops or with the board looping 3 times and then saying "overclock failed" after being powered off for some hours. I think that person has posted in the main GB thread before, but his problems went away completely, after he switched RAM (I think he was using a brand of gskill without a proper XMP profile and then he switched to another gskill, which solved all of his problems completely).

I haven't had a single boot loop on my UD5 board with BIOS F7, and I'm using 4x4 GB of Gskill 12800 XL (not RL) Ram on it. The only times before I ever had boot loops was trying to use S3 sleep with PLL overvoltage enabled (and that was F3g), and I think they changed it now to restart the computer fully from Post now, if PLL Overvoltage is enabled, and of course, an overclock failed if I press Reset.

The only other time I had boot loops was the 10 second on/off restart occasionally with f3g (didn't even display the post screen), and I solved that by increasing the RAM voltage to 1.53v. I think Gigabyte increased the default DDR voltage to 1.52v in F3 final and newer bioses, maybe for that type of reason.

Can you tell me exactly how you flashed the BIOS? Like exact procedure of everything, just in case...
BTW here is how you flash:

BTW This is the proper way to flash the bios:

download flashspi and the bios image. Make a USB flash disk bootable (there should be windows 98 startup files available easily if you search google), and then you can format the drive and make it bootable with the HP USB format storage tool.

Then after readying the flasher and files, you should do the following:
1) set the computer to stock (if not already).
2) Restart the computer (you may have to set the BIOS to boot from the USB). Boot to DOS and flash the bios from there.
3) power down the computer completely after the BIOS flash is complete. Do NOT restart the computer. Then switch off the PSU rocker switch. Then wait 60 seconds. Then press the case power button, still with the PSU unplugged or switched off. That should get rid of any remaining standby voltage. Then open the computer, and either short the clear cmos pins with a screwdriver, jumper block from a HDD, or the Clear cmos button if you have a button. Keep it shorted or pressed for 30 seconds. Then remove the jumper, hook everything back up, and power the computer back on. You should get a clean boot and be able to set your stock settings. After you verify your settings, you can then flash the backup BIOS by holding alt F12 rather furiously BEFORE you see the CPU string appear after a reboot; it's MUCH easier to do this with a PS/2 keyboard.

If you are STILL getting boot loops, and you don't have any strange USB devices plugged in (some people with asus boards have gotten boot loops or hung or very long boots by certain mice or external drives plugged in), then most likely the board is bad and needs to be RMA'd.
