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!

I am at 4.3 with 1.265V applied to it. But still testing once I am 100% happy then I will post my settings. In the mean time, I dont' have cold boots etc and the ones that did happen it was my own fault to let go sleep or when playing around with the lowest Vcore possible.

Would be nice to see your overclock settings and compare with Neil's settings.

Another day with NO cold boot issues

, nearly 3days now

Updated overclocked BIOS settings!

After 3 days of no cold boot issues, today I go out for two hours come back home, turn the system on it doesn't show a boot screen with no video display it shuts itself off :mad:

. I take out the psu cable, plug it back in the system boots on it's own and again it shuts off :mad:

Take out the psu cable again, plug it back in system boots on it's own and it works perfectly back into windows :rolleyes:

I'm still going strong..

Mine is fixed

Yeh right, mine worked for three days if it's working after a month let me know what you did

MOOGLEYS · 12 Jan 2012 at 13:04

I'm being optimistic a positive attitude now my 7 days have passed for an easy return...

i see your running ssd caching,tried to see if its the ssd entering sleep mode thats causing freezing or loops? you can stop it entering sleep mode somewhere in windows settings or maybe bios,worth a try,same thing for your mechanical hdd

He doesn't really undestand that concept. I already told him that sleep mode will make you go into serious cold reboots. Also stepping cpu speed causes instablity. Basically you are letting the cpu choose the speed it runs and and hopefully the motherboard gives the right amount of Vcore instead of a constant. But hey its your computer.

To acheive a better OC it is even suggested by other pros to turn Turbo off. But hey he prefer to cold boot and then blame gigabyte.

I will post back after a month. At the present moment my rig have passed 24Hour Prime and at 54C at 1.265V applied to Vcore.

I already passed IBT at very stressed level 20 loops.

No cold boots. Feel stable. After tomorrow I will try to restart and reboot 100 times to see if I get any cold boots.

Guess what neil next time you go out again and come back home you will have the same problem.

Threepwood · 12 Jan 2012 at 16:52

I haven't had any cold boot issues at all :S

Why wait so long to post your settings? Post them up and thenwe can all try them and see if they work in our systems...

It should still resume from sleep when oc'd and power saving enabled,never had issue with boards I've used inc x68 v pro @ 4.5ghz,it can only be BIOS or hardware/component or BIOS setting related

MOOGLEYS · 12 Jan 2012 at 17:04

Mine resumes ok from standby. I never turn it off so is always in and out of standby and that has not caused a cold boot...

NO point posting if my settings are unstable. So after a months then I will post mine. Again once my prime 95 finishes tomorrow then I will do 100 shutdowns and restarts to see if any cold boot issues.

I don't think my pc will ever see 100 shutdowns in its life time.

If you post what you have so far we can all try them on our systems and see what we can find. Everyone has a slightly different setup so what works for one might not for the next.

I *think* I have a stable 4.5ghz overclock, although I think I could probably knock some of the voltage off after a bit more testing. I also have the UD3P motherboard, i5 2500k and 16gb memory.

coretemp says voltage is 1.3861 maximum , maximum temperature on a maximum test on intel burn says 69degrees and intel burn says 65Gflops.

does that sound about right?

Henryg40 · 12 Jan 2012 at 18:37

Actually for some reason 65gflops seems low?

realscot · 12 Jan 2012 at 21:14

Too true about not trusting auto settings in bios. Mine on totally stock settings put the cpu vcore at 1.38v at stock! stupid board. Oh well 4.2ghz is easy and I can't be bothered to go any faster at the moment

I don't use sleep mode and never said I did and where Am i letting the computer have control of the speed?, I've set TURBO to 4.7GHZ and adjusted accordingly it's what you should do. I also adjust the VCORE myself not the computer. Turbo is the better option it saves on energy and is only in use when it's needed, there is no point having it running at 4.7ghz at high volts all the time.

I've done my research and you've done yours however if an ASROCK board or an ASUS board can do generally the same settings and use TURBO and have no cold boot issues. IT'S THE BOARD or the BIOS!. Until you can prove one way or another what the certified cause is of any cold boot issues i'd love to hear it. So far people have been told, its' because they didn't bios back up, then it's because they have quick boot, then it's because of the VTT.

I am not here to argue with you. I just want to be helped and or help others if needed. I must say I am sorry I read your post wrong earlier. I thought your computer went to sleep mode and when you came home you can't turn it on. That happened to me when I went to sleep mode and it went on a loop reboot forever untill I had to take control of it by pressing power untill shuts down and then do all the unplugging and clear comos etc to get it back on again.

You adjust the vcore yourself. True you set the vcore in the bios. But when the CPU steps down or up it also choses the amount of voltage that goes into the cpu unless you put it at a constant. So lets say you give it 1.34v to get to 4.6 but when it is stepped down your voltage will show 1.045v or whatever. During those times it is not in your control what voltage it uses.
But hey buddy again it is your computer you can do whatever you like.
I can't prove anything but nor can you prove that it is your OC thats not causing the reboot or booting problems because I am not encounering any. The ones I have encountered I know I've made them.

In a month I will come back when I am certain that mine is rock solid. To tell you the truth I also have turbo on. You know why? Because I also used part of your template. I just left it on at the moment but I've read somewhere that it is better off. Because I am not having any problems at the moment I am leaving it on.
Others settings I have disabled and changed from Auto to a specific range or number.
I will turn speed specturm off after I finished my prime. So far my prime is still running and no errors (31 hours running)
