Gigabyte EX58-UD5 : Cold boot problem.

[johnnyw]

Hey,

So the problem is that everytime i turn off the pc even for few mins and then turn on again it starts -> shuts off 2-3 times before it finally posting normally and loads windows. Is this some known problem and if so is there any tips how possibly fix that? Also i need to mention that it happens at completely stock too and not only when overclocked. This is pretty frustratiing as pc is working 100% fine apart from that boot problem

Comp details is:

Gigabyte EX58-UD5  with F12 bios
Core i7 920 D0 + Prolimatech SuperMega
3x2Gb Team Group Xtreem 1333MHz CL7
Sapphire HD6970 2Gb
Corsair F60 SSD - Seagate 1Tb HDD
Corsair HX750 PSU
Fractal Desing Define R3

Thx,

Joni

Well this is a known issue with Intel platforms when overclocked. It doesn't affect them all but it is quite common. Why it happens at stock though I don't know.

Have you updated the BIOS to the latest version ?

Have you synchonised the Backup and Main BIOS ?

What slots are the memory modules in ?

Have you run Memtest86+ thoroughly ?

F12 i have installed is latest official.

No idea about that syncro thing? Where it is located at bios?

Ram is  in white slots (1,3,5)  as suggested by manual.

And yes i have runned over 8 hours with memtest, prime95 blend overnight  + also  40 runs linx with max mem usage without single error. As i said computer works 100% fin and stable in windows, havent had single problem apart from that annoying boot thing.

Things ive tried so far.

Clearing cmos completely
Tried several different ram settings ( 1066 CL7,8,9/1333 CL7,8,9 /1528 CL8-9) and voltages almost all beetween 1.5-1.66v.
Tried to unplug secondary HDD and ODD

and many other random bios settings and none of those have made any difference

Well chances are it won't help but in the offchance that it might try this to synchronise the BIOSes.

To check what versions are already intalled, go into the BIOS and on the MAIN page press F9 for system info.   You should see both BIOS versions listed, if they do not match please update the backup BIOS to match the current.

To do that, reboot and where you would normally press DEL to enter the BIOS, instead press Alt + F12, this will flash the Backup BIOS with the MAIN BIOS contents.   Do not worry when you see a recovery comment, that is normal and means it is flashing the backup BIOS.

Ok thx, ill check that and update if its not the same as main bios.

[johnnyw]

Well secondary was F7 but now both are F12, also cleared cmos with button in back and even taked battery out for few mins . Weird thing is that now at totally factory defaults with only boot priority changed it seems to boot normally, but  immideatly when i change even one setting concerning cpu it starts to do that same double/triple boot thing again. This really does suck bigtime, my previous Asus and Msi s1366 mobos never acted like this.

Does it do the same thing with an older BIOS installed instead ? F11, F10 ?

Have you loaded Optimiised BIOS Defaults after clearing the CMOS ?

Ye meant optimized defaults after clearing cmos and with those it works fine, but if i change even one cpu setting or cpu concerning voltage away from auto that problem occurs. Havent tried any older bios version so no idea about that, but i dont really want to try my luck with those older ones either.Few guys at  finnish forum reported that those had problems with some sandforce SSD drives that those wasnt regognaized at all in bios.

I am afraid that I don't know what else to suggest then apart from contacting GGTS and asking them.

Ok ill contact support then but i affraid that they wont be that helpfull as  afterall it seems that the mobo works fine when totally stock First gigabyte board for me and this kind of things wont ever give nice impression. Just googled a bit and seems that this is pretty common problem with this board, sadly there doesnt seems to be any straightforward fix to it as it happens randomly for some users and for not for some.

Thx anyway.

Yes I know what you mean but it might not be the motherboard at fault anyway.

Just a thought have you tried adding a HDD delay of say 5 seconds in the BIOS. Worth a try anyway.

Well really cant think what else would it be than mobo,cpu,ram,gfx,ssd,hdd psu has been working just fine with asus and msi boards i had before. Well could be some compatibility problem but i doubt it, usually in that case if like ram isnt compatible it dont work at all then. But ill try that HDD delay thing but i doubt it is that as it wont beet that long that it start to detect hdd:s before it starts again.

Just tested and its like this.

Pushing power button -> starts -> 5 secs later starts again- 5 secs and starts again -> finally posting normally

Led thing in mobo says C1  just before it starts again, didint found that code on manual so no idea what it means.

I expect it is down to the memory. Just because your memory worked before doesn't mean that it is alright now or that it is compatible with this system. Have you checked the manufacturer's QVL on their website for compatibility with this board ?

Are they a matched kit of three modules ?

Memory is one of the first things that is checked during POST.

Ye its matched 3x2gb kit and team group website list this kit compatible with this board. Also just tried set ram at rated speed to 1333mhz cl7 and it works fine as long i dont touch any settings for cpu.

In that case it sounds like it could well be the CPU that is problematic. If you purchased both the motherboard and CPU from the same retailer then I would suggest returning them for investigation.
