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.

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?
-
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?
-
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.
-
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. :o

Dark Mantis I am speechless. It would be the last thing that I would believe but I saw it happening in front of my very eyes(I was present while the repair was taking place!).
To be honest, I won't be surprised if the Asus has the same behavior after a while. Right now I am working on the specific PC and it always detects 12gb.
What can I say. It is true however that there are very few people right now stuffing their motherboard with so much RAM so the problem, although it is widespread(googling does yield many results), it is not so common to the majority of users.
-
The only thing that makes me sceptical is that I personally know of several people with X58 chipset motherboards(Gigabyte and admittedly X58A type but it shouldn't make any difference) that have 12Gb and are running fine. ???
Did they try the same motherboards with less memory while you were watching?

IMPORTANT
As this seemed to be of significant importance I thought that I had better take some advice on it. I have conversed with the TweekTown guru Lsdmeasap and he has clarified the situation. For a start this is a problem on 1366 and to a lesser extent 1156 socket motherboards not just Gigabyte but all makes. Most of the time the issue is bent pins on the CPU socket as we have already noticed here in the forum. This is really a bad design by Intel and common to all makes.
The quotes I will introduce are all from Lsdmeasap, so a big thanks to him for his help.
This issue you mention is common with ALL 1366 motherboards, 4GB out of 6GB, or 8GB/10GB out of 12GB. It''s usually about 65-70 % caused by bent socket pins, 20-25 incorrect QPI/Vtt - dram voltage relationship or improper uncore settings, 5-10 % faulty ram (Usually less often), and very small percentage can also be caused by uneven heatsink pressure but this isn't very often at all.
Users always blame the board, no matter the brand too, they always say this happens with all XX brand boards (Whatever they are using) like it's a brand issue. It isn't, it's really a poor Intel design issue by putting the memory controller in the CPU with all those super tiny thin pins
I can cause it manually anytime on the fly with incorrect QPI/Dram voltage, too high/low uncore, memory frequency too high for all settings, or incorrect timings even. Eva2000 made a NICE thread here (For Asus ) users, explaining the MANY things that can cause this. You'll see the "Possible Causes" list and tips right under the images
http://i4memory.com/ramdetect/
To make it easier to understand there are some included images
I have actually done a few tests in the past for people who thought the same about it being a "Gigabyte Only" issue. I show them these results, 12GB two ways. One way is two different sets of memory at 1600Mhz 12GB, the other is with 3 mixed sets adding a second brand in as well, with taskmanager showing ram total in each as it's the main place you can notice the problem. It's also easy to spot in the BIOS with SPD set to Expert then look at each channel timings one by one, failed channel will show up as N/A or -

12GB of mixed memory @ 1600Mhz. 3 different sets mixed, all with different timings and IC's, even a second brand threw in to mix it up. Each channel set to spec of installed memory, so this is REAL Triple channel

*Also note, this can affect 1156 as well, Dual Channel is just not as hard on the IMC/QPI, so you don't see it as often unless there is bent pins or voltages are way off*
I hope this helps clarify the situation for anyone in this predicament and also demonstrates that this is not a Gigabyte only problem.

Hello Dark Mantis,
Very interesting information, I have no doubt this is the case.
So, what is the solution? If we suppose that the voltages are correct, there are no bend pins what can let all those users that have this problem use all their RAM?
Is the solution going to come with future BIOS updates for their motherboards? I am an audio professional working for the music, film/tv industry for many years on PC's, and honestly, after experiencing this problem, this is the only time I have been thinking of switching to Mac.
-
Well from my digging and what I have been told by Lsdmeasap at least about 3/4 are bent pins and the rest are nearly all wrong QPI/Vtt, memory or uncore settings. The actual faulty memory modules that cause the problem is negligable. Obviously it has to be taken into account but as you can see the majority are by far faulty CPU sockets. As it happens this would go along with the trend that we have been looking into already on the forum but didn't realise the link. We also assumed it was a Gigabyte only problem but it can be any manufacturer. This link is relevant for the ASUS boards: http://i4memory.com/ramdetect/
I think that only a change of socket design is going to cure this problem. That is not much comfort for the likes of you and me with the 1366 socketed boards but at least we know what to look out for. Obviously a BIOS update or any other software fix is out of the question.
-
Dark Mantis please have a look here and let us know what do you think:

In the last post.
This could also make sense, however,after searching, I found out that the sockets are obviously problematic.
-
Yes I would agree with what was being said there also. He was just reiterating what we have already said regarding the voltages on the ones that fail due to wrong settings. Obviously it isn't going to help those with bent pins. Actually I noticed that he said on there that the Gigabyte BIOS releases were normally better which is one of the main reasons why I moved from ASUS over to Gigabyte in the first place.

If any of you guys need help with your voltages or settings to try and correct your issues let me know as I can help for sure!

I can vouch for this guy. He is very well known on the TweakTown Forum as a Gigabyte guru and can certainly help with any setting problems you might be having.

Is relevant for ALL X58 boards, it just happened that Eva2000 wrote it while using an Asus board, so anyone with issues should check it out for all possible causes and or solutions for this issue.
