Gigabyte EX58-UD5 : Cold boot problem.

[johnnyw]

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.

CPU is bought different time than motherboard and from different retailer so thats not really option and really dont think it cpu in fault here anyway. If you google "EX58 UD5 cold boot problem" you get loads of  hits, seems that this is really common problem with this board. Some peoples even have this same problem with newer X58A-UD3 gigabyte board  like this guy -> http://youtu.be/PSsDqdjDTfg?hd=1

Also as i allready said these problems started at the same moment when changed to this mobo from P6T SE, with that mobo and even with MSI X58 i had before that all was problem free.

It could be that there is some setting at bios that causes chipset to reset itself ( what is most likely the cause of that boot loop ) when cpu is overclocked/settings changed but no idea what it could be. I also noticed that with differen blck it boots different amount, example with 160blck it boots 2 times, but with 180 blck+ 3 times.

This is just really frustrating as pc is totally stable even at 4GHz (21x191) but that boot thing is really annoying.

Taked vids of both stock boot and "oc" boot to show how it differs

That oc multiple reboot thing happens everytime i chace some cpu settings, even small increase to blck like to 150 makes that to happen and not only "high" blck:s.

Any ideas, or is only way to rid of that to change mobo.

I know that the board works fine at stock settings but what happens if you just try a very small overclock ? Do you have the same problem ?

Well with blck like 145-150 still same behaviour, only difference then is that it only boots 1 extra time instead of 2 what happens with blck over 160. I even have tried to underclock uncore & ram but made no difference.

As I explained earlier the extra boot cycle is common with overclocked Intel boards so I am not surprised at the extra cycle. Does everything else work as intended at that point ?

Ye everything works perfectly stable. I just wonder why MSI and Asus boards didint behave like this if this is suppose to be "feature" while overclocked. That adds like 30s extra to boot time and makes my SSD totally pointhless what i got basicly to get faster start/loading times. Its really quite funny that now PC what is a lot faster now than stock actually takes ages to get into the windows because of that stupid triple boot/post.

It is not a Gigabyte "feature" it is something common to Intel platforms. It doesn't happen on all but I have personally had it happen before on Asus boards. I used to be on the Asus forum before I came to Gigabyte.

Ok, well then i think only choice is to change mobo. Shame really as feature wise this board would of been way more than enough for me.

Would really want to get some detailed explination why this happens, ive seen loads of talk about it but havent personally ever got this before, and i have owned like 20 difference pc:s in last few years including X38/P45/X48/P55/X58 intel chipset boards from several different manufacturers. Its pretty odd that manufacturers claims that this is normal behaviour as when peoples rma their board and then the replacement one dont have this so called feature anymore even when all the other parts are same. Would say its quite weird "feature" atleast LOL.

By all means RMA your board and see if that cures it. I can understand your skepticism and quite rightly so but it is one of these things that happens and I spent more than enough time on my first board that had it happen to without ever finding a cure. It could even be in the microcode of the CPU that the fault occurs.

[johnnyw]

I could try to rma it, but then again im pretty sure retailer wont exchange it when it works fine at stock settings. Retailers here is finland are not as compassionate for overclockers as they are in some other countrys

Oh well i think ill just leave this as backup board and buy some new one.

Sorry I couldn't help you more but there is a limit to what we can achieve.

[johnnyw]

Well big thx anwyay that you atleast tried to help.
