I5 2500k - Gigabyte Z68XP-UD3P Overclocking

F7C is the worst bios i've ever used to get it working right with boot loops and a cold boot issue. The Bios still sets the VTT too low when set to AUTO and using xmp Profile 1, the vtt volts don't increase and have to be manually set. But with Bios F7C I had trouble even getting that far!

1. Made sure my bios was set to default settings and used my usb stick to flash to the new F7C.

2. I powered down the system as it told me too, took the psu cable out, pressed the power switch on the psu and system to clear out any left over voltage and also cleared the cmos.

3. Powered up the system and it instantly shut off with a cold boot issue, it did this again after that. So I took out the psu cable put it back in and tried again. I was able to get into Bios.

4. Set to Default settings and rebooted, It hung on the Bios logo so i hit the reset button. Apparently the reset button can cause awful boot loops which it did. It then ended up in a continues boot loop which never happened in any previous bios flash. I was finally able to get back into bios and again set it to default and then it worked.

5. As i was able to set it to default I then proceded to flash the backup bios.

6. Rebooted the system and back in bios it said failed on overclocked settings, even though I had not done any overclocking!. I also noticed again that the VTT voltage as still only at 1.056v when on auto with XMP profile 1.

7. Set my overclocked settings, set the voltages as they should be because VTT and Main memory voltage on Auto doesn't work I was able to get into windows.

I'm not the only one with this board that has either a continuous boot loop or a cold boot issue and before anyone says it's your overclock IT ISN'T. It can do it on default settings as I said in the earlier steps. I should not have to go through all these damn steps just to get the system to stop boot looping. The VTT/QPI issue needs to be fixed aswell.

My advice stick with F7B for now

Forgive the ignorance as I'm new at this, but I noticed the CPU Clock Ratio is only 33X, surely that means you're only running at 3.33Ghz?

No as i'm using INTEL BOOST TECH clocking, it boosts to 4.7ghz when needed :)

INTEL BOOST TECH [ ENABLED ]
RATIO 1 - 4 [ 47 ]

33X is the cpu default
 
Well I spoke to soon. Whilst in standby it decided to start cold booting again.
2 hours later I now have a dead SSD. Enough is enough with this god awful board it's going back as not fit for purpose and I will get something else. I will also claim from Gigabyte for my now dead SSD.

I'm on the 7B bios.

MOOGLEYS can you please report this issue and everything that has gone with your board on to GIGABYTE?

Best way to deal with the cold boot issue is when it shuts off, take the psu cable out the back for about 5-10secs plug it back in, it should start up again and be fine.
 
  1. Support GIGABYTE TouchBIOS
  2. Support Intel 22nm CPU
  3. Improve OCZ PCIe SSD compatibility
  4. Support Dolby Home Theater PCEEv4 (Note: Please update the latest audio driver for Dolby Home Theater PCEEv4 support)
  5. Intel 22nm CPU support update

Give it a week and see if it cold boots , Mine didn't cold boot for 3 days on the F7B bios but was awful with F7C
 
Same cold booting issue this morning with either BIOS and stock settings.

Board is going back today and will order a replacement later. Last time I use a gigabyte board.

Edit - just rang the retailer for an rma and was told that they have had a lot of these boards returned for this issue?

Yet this morning, no cold boot issue whatsoever... This Z68XP board issue is finicky!
 
Also just read this

Mine seems to be resolved after using DVID instead of LLC for overclocking. System booted up on first try.


Had a reply from Gigabyte support

Hi,

Yes F7A is older. Please update and feedback the result. We have test both F7C and F7a and it solve the cold boot issue.

They are not listening at all, I've got people on other forums saying that the F7C doesn't solve the cold boot issue, sometimes it happens and sometimes it doesn't. I could boot later and be stuck on the cold boot issue. So far they've released F7A, F7B and F7C each time support says " it solves the cold boot issue ". I found F7C to be a terrible bios release, F7B lasted 3 days before it cold booted. A number of users found that the F7A and F7B cold boot issues started straight away.

Also being told constantly how to update the bios correctly by some is annoying, just because the bios was cleared, voltage cleared out and bios backed up doesn't fix the main cause.

Think i'll give up, if the cold boot issue happens I'll just pull the PSU plug, put it back in and have it boot as normal, Then use the system as when it's up and running it's perfect.

I get the problem at stock. It seems to make no difference if overclocked or not. It has once again stopped my ssd working and each time I have to put it in an old system to get it going again....
Board is out now and in its box which tbh is the safest place for it....:)

Another reply from Gigabyte support!

Answer - 1173826
Answer : Hi,

Another Cold Boot issue Bios released...
 
It is true what you say about AUTO that you don't know if it's off or on but gigabyte assured me that when it's set to auto it's most likely ON unless it's been disabled. Auto = ON. As for the cold boots they are happening to people if it's at default or overclocked, some have it even on optimized bios settings. It's just so sporadic, but I did read that turning off the bios logo and quick boot is a better way about things.

Need more updates really

EDIT : I'll put them to ON just to be on the safe side, I want the cpu to downclock which it is doing which shows AUTO is working :D

I have just bought Gigabyte z68x-UD5 motherboard and after reading few threads regards to boot loop for cold boot issues i don't know if i have made right choice.

Is this problem common with all the gigabyte Z68 chip motherboards?

At this current time it's a sporadic issue with no certain cause but I wouldn't update your bios unless you really need to :). Even if it does cold boot, just take the psu cable out put it back in and let it boot again normally. The board is pretty damn good even if you have that issue! :D
