Title: GA-Z68X-UD4-B3: Keeps rebooting after cold start
Post by: roks on May 21, 2011, 10:03:44 pm
Hi All,

Back to Gigabyte, after the last couple of boards failed just days after the warranty, I was a bit disappointed, so I went Asus. But now I am back with the Z68 series boards.

I do have one gripe with this new Gigabyte board, that is the rear I/O shield. It is so flimsy and the little prongs dont even touch the ports and the slots do not properly align, leaving gaps and the bit that goes between the port is not even metal, just the decorative plastic. 

For peace sake, Gigabyte could have done a better job than that, follow asus, they they have metalic foam cacking which makes it air tight as well.

Having paid £160 for this board, I expected top notch...sorry, rant over, just had to get it out of my chest, now can someone give me some quidance on the overclocking please.

I can set it to 4.5GHz and it will run fine with prime95, no crashes what so ever...until I turn power off at the socket and cold boot.  It keeps rebooting itself, after the first reboot a message comes up saying a problem occured due to overclocking, then it goes in a continues loop. I then have to reset the bios by shorting the  pins.

I then tried to lower the speed, thinking maybe its too high, but 4.4, 4.3, 4.2, 3.8, they all have the same symptom, when I cold boot. worm reboots are fine no problems, just when I turn off the power at wall socket.

The only thing that I am changing is the Multiplier and the memory is set to XMP profile in 'normal' mode.

Do I need to change anything else?

Thanks in advance.

 Hiya ROK......
   Try forgetting about XMP....disable and set Manually and see if this makes any  difference to your problem........To answer your other comments........I thought you said you had only one gripe?.......... So why did you leave Asus for the problematic Gigabyte boards.......You could have shot yourself in the foot starting with a scathing attack then asking for advice, ... with so many of the top minds on this forum being ardent Gigabyte supporters , somebody may-well tell you to plug it into a 415v outlet to rectify the problem...........Post your findings as I'm sure being such a new chip/board, ...people will be interested whether it's a board fault or pilot error.

 Aussie Allan
:D Maybe I should have said "one item" lol....seriously though, it is flimsey.

So why did you leave Asus for the problematic Gigabyte boards

I came back to Gigabyte because I read of issues with the Asus boards, also there is nit issue with the board, just I/O shield.

I will try with manual settings and update you guys.

Another thing, why does the Motherboard temp always 40oC, is that ok?

 New board/chip! Don't really know.......When DM wakes Up in the morning he'll see this post and make a better qualified comment to this question.

 Personally I have heard these new boards are warm, but not hot enough to cook an egg on.....when you say , 40C    is that the max you see it reach or is this a constant temp from boot and /or idle through to load ?.......Do you have plenty of air movement through the box ?.....see how you go with the manual timings

Hi,

I've tried setting the memory manually to 1600Mhz, its still doing it, even at stock speed....

This morning I tried with setting the memory to auto which picks up the memory as 1333Mhz (xmp disabled as well) and that seems to fix the issue.
I'll reconfirm when I get home.

These memory kit is 1600Mhz @1.5v, so not sure what the problem is, hopefully updated bios will fix it...   

Thanks.

Post by: Dark Mantis on May 22, 2011, 10:37:21 am
Hi

I would think that it is a BIOS issue probably. I haven't had anything to do with the Z68 boards but I am familiar with the P67 which is basically very similar and they run quite cool compared to previous versions. Does the temperature change or is it always the same ?
Title: Re: GA-Z68X-UD4-B3: Keeps rebooting after cold start
Post by: roks on May 22, 2011, 11:24:27 am
Sorry, for got about the m/b temp, it starts at 38c then goes to 40c after a little while...with prime95 running 42c.
I have 2x92mm fans bottom front, a 120mm at top reat, and a 120mm on the vga.

I did not change the memory voltage, I assume its 1.5v, xmp detects the memory correctly, 1600@1.5v.
Title: Re: GA-Z68X-UD4-B3: Keeps rebooting after cold start
Post by: Aussie Allan on May 22, 2011, 11:56:28 am

 I'd be surprised if the memory runs stable, 1600@ 1.5V....I thought 1.6v would be the minimum....really hard with such a new board......AA  what do you think DM?
Title: Re: GA-Z68X-UD4-B3: Keeps rebooting after cold start
Post by: Dark Mantis on May 22, 2011, 12:28:13 pm
There is no reason that the memory can't run stably at 1.5v as long as that is within it's specs. Why are you concerned by the motherboard temperature anyway ? It's not that high and obviously the sensor is working and not stuck as it does change with the load.
Title: Re: GA-Z68X-UD4-B3: Keeps rebooting after cold start
Post by: roks on May 22, 2011, 01:01:24 pm
DM - Not too concerned, just that my p65 m/b was some thing like 27c idle.

I purposely bought the 1.5v memory because I thought these boards needed that, could have saved some cash if I had bought 1.65v.
Anyway, how much performance am I losing by running it at 1333? I'll live with that for now.

Thanks
Title: Re: GA-Z68X-UD4-B3: Keeps rebooting after cold start
Post by: Dark Mantis on May 22, 2011, 01:21:10 pm
To be honest I doubt you would even be able to tell the difference using everyday programs between 1333 and 1600. I expect we could get it to run at 1600 anyway but you would need to manually set the values but you would probably have to sacrifice some CPU speed to do it.
Title: Re: GA-Z68X-UD4-B3: Keeps rebooting after cold start
Post by: roks on May 22, 2011, 01:31:09 pm
Ya, I was thinking the same, leave at 1333...

Thanks to both you guys.

Hi Guys,

I've done some further tests and it appears that it may not be the memory after all. Yesterday the same symptom, with the memory at 1333.

I thought it might be the overcloking but it did it at stock speed and all the way to 4.5ghz.

I am wondering could it be the PSU?
Title: Re: GA-Z68X-UD4-B3: Keeps rebooting after cold start
Post by: Aussie Allan on May 24, 2011, 03:57:43 pm
 Sigh!..........this is why it's important for all information to be put on the table when posting a problem........even my Crystal ball craps out at over 400 miles.....mind you , excellent your getting somewhere

 What PSU ?...what Wattage ? how old is it ?.... Keep in mind what DM said about ..."I think it's a BIOS issue".... are you running the latest Bios update (non-Beta) and have you tried Backing up your BIOS and rolling it back to the one before and retest ?

PSU is Antec NeoHE 550Watts, bought mid 2007, this is high efficient version, 88% half load, rest of the the stuff are in my sig.

I flashed the BIOS with the latest version, F6....thats the only one on the website, unfortunately I did not back it up.
Would the 2nd BIOS have been flashed as well or can I rollback somehow?

What I noticed this time is that the pci tv card had disappeard and little speaker does not beep. Got the tv card back by re-inserting it but beep is not working, I think I have to short the cmos pins to get that going.

 Might be still in download if you went this route.........either way, move on.

 If anything is not clear, ask for more detail, ... turn off power, unplug and short pins of BIOS, reboot and Bios again, load optimized default, save and boot........go back into BIOS and load all your setting for your system......save and try and reboot back into windows per normal and see if things are better....post results of what's changed if at all.

AA,  I did as you suggested, the single beep came back. I am going to run with the default settings and see how it behaves.

But more twist to his upgrade, i just noticed that in the bios the turo boost is at 3.4ghz, when i run prime95 it only goes up to 3.41Ghz. I checked the spec on intel site for 2500k, the turbo should be 3.7ghz.....damn i wish i kept a backup of the old bios... so as DM pointed out BIOS.

yep, triec that, highest it goes it 3.4.
I noticed in the bios the auto detected c1-37, c2-36, c3-35, c4-34, so i guess with all 4 cores going 3.4 is the max?
Title: Re: GA-Z68X-UD4-B3: Keeps rebooting after cold start
Post by: Dark Mantis on May 25, 2011, 03:40:37 pm
If you want to flash back to the Backup BIOS then folow these instructions. It might take a few tries to get ti right though.

You can kick in the backup BIOS by shutting down the PSU from the wall, then hold down your case power button in and then turn on the power supply button, a few seconds later the board will start, shut off the power supply then.   Then you can turn on the power supply again and power up the board normally and DualBIOS will kick in.

Hi,
stumbled upon this post while doing a Google search. I'm building a new pc, HAF 922 casing and Gigabyte GA-Z68X-UD4-B3b mobo. The I/O shield doesn't align properly with the mobo slots, it's only slightly off center (1 millimeter to the left) so i can still plug everything in but it still bugs me a little. Checked the casing and mobo for warps but both seem to be competely true, standoffs are all standard height, mobo holes align perfectly. I'm wondering if this with the I/O shield is a common issue or just my bad luck.

Hi

I too have the HAF 932 case and although I haven't got the Z68 motherboard in it my UD7 fits fine.  Firstly I would suggest that you re-examine all the fittings and make user that there is no user error involved. If not then as you mentioned earlier find some shorter posts.

Post by: roks on May 29, 2011, 04:06:36 pm
DM, I tried several times to invoke the backup bios but no luck, I cant go back to F5....not sure if that will make any difference.

I also discovered that my PCI tv card disappeared again, this time when I removed and re-inserted the card, it didnt work. So I moved it to the other PCI slot and that worked for a while....until I turned on the PC few hours later, the card has disappeard again, this on a fresh install of Windows 7.

Yayo,
About the I/O shield, its cr@p, mine does not align with usb slots at the top (next to keyboard). I noticed that the ports are a bit buckled/ or that corner of the board is..so I put the keyboard in, pushing down slightly on the keyboard, insert the usb stuff.....but its sitting aligned on the stand-off perfectly.

I have raised a ticket with Gigabyte, the guy said he will let the HQ know about the I/O shild issue, I suggest you do the same, so that they know its a wider issue. I wouldnt go cutting stand-off's if other boards fitted fine why should you have to fiddle with these?

Could you do me a favour, if you have not updated your BIOS, could a make a backup of F5 bios and attach in a zip file to this post?

Thanks

You two are the firsat ones I have heard complain about this lining up problem. I would suggest that you both contact GGTS so that they are aware of it although if it was a major issue I am sure there would be many people moaning by now.

Try flashing the BIOS back to F5 then and make sure that you untick the "Keep DMI Data" while running the update. Afterwards load Optimised BIOS Defaults in the BIOS.

@ roks
I'll gladly post the bios but am waiting for a Noctua CPU cooler to right now, assembling my mousetrap will take some time, hopefully less than a week.

@ Dark Mantis
I'll do as you say, take everything apart (again) and examine the trueness of the mobo tray and mobo itself with a ruler, then measure the lenght of every single standoff. When 100% sure that it wasn't a mistake on my part, then I'll contact support. But I'm not touching anything before the new cooler arrives.  :)

Hi guys,

It seems I am having the exact same issue with the constant reboots after cold start. I tried with F6 and the latest F7d BIOS with no luck. I tried clearing cmos, loading bios defaults, even took out the battery for a while, but the problem stays there. Even when using optimized defaults the cold boot cycle is still there! I can also get it to 4.5Ghz Prime Stable and then, if I power off, the system will go again in a post cycle that after a NON standard number of reboots ends up at the OC FAILED boot screen. I am using a 2600K with 2x4GB Kingston 1333Mhz 9-9-9-24 DIMMS, temps are ok and I really have no idea what to try next.
Title: Re: GA-Z68X-UD4-B3: Keeps rebooting after cold start
Post by: Dark Mantis on June 05, 2011, 10:25:13 am
Hi

I would suggest that you try an extended CMOS clear as the way you did it before doesn't always work.

The next thing to try is to clear the CMOS.

Remove the power cable from the mains supply and then press the power switch on the case for a few seconds just to drain any residual energy in the PSU capacitors.

Once done remove the motherboard battery for at least six hours before replacing it.
 
Next plug back into the mains supply and boot.
 
You will now need to enter the BIOS by pressing DEL and load Optimised BIOS Defaults.

Make any other changes to the BIOS settings to suit your self like disabling the floppy drive, disabling the full screen logo and making the HDD the primary boot device and then press F10 to save and exit.

Thank you for your suggestions Dark Mantis,

I did as you suggested, and the first reboot was successful. Then, I applied the OC settings (nothing too aggressive, no CPU PLL OV, mem manually at 1333Mhz low timings etc) and tested them in windows. Everything was fine and stable. After a few minutes I shut down the PC and powered on. First post was not successful and then the second post started fine but by using the default settings!

 Any other suggestions? I can tell you also that the same thing is happening even with NO OC settings, PC tries to post once and then restarts to post successfully!

Hello,

I came across this forum as I was suffering from the same cold reboot problem as described in the first post.
I had everything set at optimised defaults. Tried all the official and beta BIOSes, tried underclocking everything, reset CMOS, pulled out the MB battery, flashed both BIOSes so they were the same etc,etc....no luck, until Monday.

The problem to me appeared to be that the CPU was not getting a chance to power up.

In a last ditch attempt, I changed the "Delay for HDD (secs)" in the Advanced BIOS features to 10 seconds.

After changing this setting, my machine has not once exhibited the cold reboot problem (5 days). It has frozen once when doing the memory timing check, but a press of the reset button got it going again.

My settings/system specs are:
Official F7 BIOS
i7 2600k @ 3.7 Ghz, 8Gb G.Skill PC1700 Ram @ 2133Mhz, Gainward GTX 580 3Gb video card (stock timing), WD Black 2T HDD in AHCI mode and connected to SATA port 0, Corsair 850W PS, Lite-On BD drive which I have connected to one of the SATA 2 controllers, Antec twelve hundred case.

I joined this forum in the hope that my fix might help you out. Good luck.  ;D

Hi and thanks for the input.

The HDD Delay is a useful tool and usually helps if a slow drive is used as a boot drive. Most modern drives, except "Green" varieties don't require this to be used but sometimes it can help. Ten seconds though is quite a large delay.
Title: Re: GA-Z68X-UD4-B3: Keeps rebooting after cold start
Post by: Damo on July 16, 2011, 10:28:52 am
After more testing, I have narrowed my reboot problem down to a single BIOS setting. (It had nothing to do with the HDD Delay in the end).

If I disable GSATA, my machine works flawlessly. When I re-enable the setting, the reboot loop is back. As I understand it, both GSATA and eSATA is controlled by the Marvell 88SE9172 chip. I don't use either, so disabling them is not an issue.

So what does this mean in terms of the integrity of my board? Is there something physically wrong with the board or is it a BIOS issue?

I have tried the latest BIOS updates including a few of the beta versions with no change in this scenario.

Any help/advice would be appreciated.
