X58A - UD3R Boot Up Issue

[Dark Mantis]

It was happening to my system when I first built it but I had problems with my Zalman 750W power supply so I installed a Corsair HX850 and that problem disappeared with my others.

I have a Corsair HX1000 and I get the same sometimes.

Right - so it's maybe a PSU thing ?!

That's fine - I can live with the 3 seconds rather than forking out for a new PSU

Tehehehe!!!

Maybe one for the next build - a 1000w Super-Dooper PSU

I think in all fairness that is the way to look at this as a minor annoyance. It used to happen on one of my old PCs and I never did find out what caused it although the computer went on for years with no detrimental effects.

I have decided to order some new Corsair Ram - the ones refererred to in the Gigabyte compatibility list, we will see if this helps as I dont believe I can do much more with the bios to alleviate the issue.

[Dark Mantis]

I would agree that is a good course of action in your instance. Please post back after you have installed and tested them with the results.

Well changing the new Corsair Ram made no difference as did flashing the official FC bios.

I will do some bios tweaking, but I dont think it wil help tho, as there are so many variables that may be causing this, i may have to leave the AC on and ignore it when I do a cold boot.

Thanks

Sorry about that, I was hoping that would cure the problem but as I said these things are not always easy to track down.  

Please let us know if you do discover the faulty component. It might be worth checking the CPU socket for bent pins when you have the time as that causes some weird problems at times.

Thanks - I really appreciate your efforts to try and help me out - it does not appear to be a very serious issue and everything else is working great.

I have a few more things to try yet and removing and reseating the CPU is one of them - I have to remove the motherboard to do that so maybe I might find something else i that excersize. I will also do a bench test with minimum components.

If I do manage to track down the issue, I will most definitely report back here, because I have the feeling that I am not the only one with this issue.

Thanks again

As I said before I have had this same problem in another machine and even this one before I swapped PSUs so I would be interested in what is causing your problem.

As far as the CPU socket check goes post a couple of macro photos here for us too see too will you please?

[Rebel801]

Yes - a faulty PSU would certainly be a possibilty, however my Corsair HX 650 was working flawlessly on my old system so I dont think that is the problem at this stage, Unfortunately I dont have a lot of different Ram/ CPU's to swap out components to isolate the issue.

I have requested a service ticket from Gigabyte to see if they can offer anything.

It may still be a faulty motherboard - although I have not observed any other problems - I have raised bclk to 160 and it runs fine. The fact that some people with identical systems dont have this problem, after testing and isolating the Ram, it could really only be the CPU or board.

BTW I did remove the cmos battery and a full reset sequence and still no change.

If the issue occurs only when the PSU is actually switch off, it is feasable that some bios settings (strap?) get reset - then when I power it on it goes through this loop before booting up. Problem is, why dont other people have the same issue?
I am certain there is nothing wrong with the way the system was installed, as I have been building systems for many years, for myself and a number of my friends.

No, I don't think it has anything to do with the way the system was built at all. It's just one of those things in computing sometimes "s*** happens".
Whilst the PSU is a possibility I don't really feel it should be a problem. As you have mentioned it is a possibility also that the motherboard could be the culprit. It is one of those hard faults to pin down.

[Rebel801]

I agree with you there

At this stage I really dont know if it is a problem or just a quirk with some intel systems. If I could try another board and it doe sthe same thing, I am still no better off - then I would need to replace the CPU.

What annoys me is that I almost went for the UD5, but I decided that the UD3R was more than enough for my needs.

There is also a possibility that the issue may be resolved by a bios update - I will be keeping a close eye on the boards to check for updates.

[Dark Mantis]

I have the UD7 and as I explained I also had the same problem at first so there is no guarantee that if you had bought the UD5 you wouldn't have the same problem.
