EX58-UD3R does not boot(no beeps)

[Alphatrack]

I just got a replacement for my UD5 motherboard. It is a UD3R and I just got it from service, the whole PC was in the service department.

So, I got the PC once, managed to boot it just one time to disable the onboard sound device, and after that the motherboard will not boot.

It does not make a beep sound at all and nothing shows up in the screen. I cannot access BIOS. I have tried resetting the CMOS but no luck up to now.

Have you got an internal buzzer attached?
How have you tried to clear the CMOS?

I tried clearing the CMOS and the beeper works because it did beeped the first time I booted the PC.

How have you tried to clear the CMOS?

Apart from disabling the onboard audio what other changes did you make in the BIOS?

That and disabling CPU EIST1.

Tried remooving the RAM and also removing the battery. The motherboard still does not boot.

Did you remove the power connection from the PSU first and then remove the battery and short the clrtc pins?

I removed the PSU power cable, pressed the Power button in order to remove any current, then I removed the battery, Cleared CMOS and moved back the battery and cleared CMOS again.

Well that should have worked. When you try and boot now what exactly happens?

[Alphatrack]

The lights come on, the dvd drives spin but the screen remains black and no beep is heard. I really don't know what else to do. Three motherboards and all of them had a different problem.

Right then you have a choice now. You either take it back to the centre that did the repair and dump it in their laps or you try and sort it yourself. If you want to follow the latter route then we will need a list of your hardware to work from.

Remove cards,RAM,HDD,DVD,USB (and the front panel one and other types).

Any beeps now?

[Alphatrack]

Right now I am at the repair center. They had to remove the CPU and place it back again in order to reset the BIOS. they said that have seen this problem with GB boards. I'll keep you posted.

[Dark Mantis]

I've not seen that problem in all the cases on the forum or outside. In that case I would get them to check for bent CPU socket pins while they are there. It is a big problem at the moment.

Hello,

I am afraid, I don't have good news. I have been in the service for the last 4 hours. They tried another 2 UD5's, one X58A UD5, 2 UD3R's , different CPU's, different RAM's, different video cards.

With each and every motherboard, the same, RAM was not fully detected on restart and when trying a cold boot the motherboard would not boot at all. They had to wait for 3 minutes to make the system bootable again.

The last thing we tried was swapping the motherboard for an Asus P6T.

The results?

System booted just fine, RAM was detected correctly in every single reboot and no problems appeared when booting.

Sorry, but I think that the motherboards were the culprit here. I did not want to have my GB exchanged for an ASUS at all, believe me. However, right now I have lost faith in GB. In the end of the day the service department contacted the central offices and they responded that this is a known problem with Gigabyte motherboards and that the reason it is not so well-known is that there are very few customers loading their system with 12GB of RAM. Obviously these motherboards cannot handle it.

I am very frustrated, because I have been counting on Gigabyte motherboards for quite some time. However my system would not work at all if I didn't switch to the Asus.

So basically you are saying that X58 chipset on the Gigabyte moptherboards wont take 12Gb of memory(or at least all slots filled)? If that is so there is a  huge problem as more people fill their boards with RAM.
