Hello everyone,
I am sorry to make my first post here with a question, but I am starting to lose all hope.
I have a EX58 UD5 motherboard (Rev.1.0), with the F10 Bios. I have 12GB of Corsair RAM(2x Corsair 6GB DDR3-1600 Ram Kit (3 x 2GB, PC3 12800, 9-9-9-24, TR3X6G1600C9).
The problem I am having is that the BIOS detects less RAM (most of the times 10GB) when I reboot my PC. The weird thing is that this happens ONLY when I reboot. If I start a cold boot, then all 12GB's are detected. I have tried all the suggestions for similar problems like, setting manually the timings, changing voltage, change RAM speed (BIOS sets it at 1033 by default). I tested each module and they work fine.
When the system does detect 12GB after a cold reboot, Windows 7 64bit work flawlessly and I can use all 12GBs of RAM without any problem whatsoever.
Right now my only option is to never reboot my system and perform only shutdowns and cold reboots.
I have sent a support ticket to Gigabyte and I am expecting a reply.
Could it be a problem with the BIOS? This could be the only logical explanation, otherwise, why on earth does it see 12GB on cold
boot but only 10 on restart?
Thank you in advance for any replies!

Whilst it seems to be logical that it is a BIOS problem, and chances are it is, the other thing that causes this problem is bent pins on the CPU socket. Now I know that sounds stupid but believe me it has happened quite a few times recently here on the forum so it is worth checking.
-
Hello,
I have checked it, the pins all seem good.
-
That's good news anyway. So that really leaves us with the BIOS. When you checked the modules did you do it one at a time and use Memtest86+?

Yes, no errors with each module. I was mistaked in my first post, my BIOS version is F12, not F10.
-
The only other update available on the website is F13j which is a beta version but it should be stable and trouble free or it wouldn't have got as far as the site. I don't know if you want to try this one and see if it helps?
-
I am a bit hesitant to try a Beta BIOS, but I would be happy to try it if there was a sign that this would fix the problem. As far as I can see this BIOS update only affects keyboard compatibility and the internal soundcard.
No mention about Memory issues whatsoever :-[
I am not sure if I should in fact downgrade my BIOS to a version that was admittedly stable though.
-
The trouble with the BIOS updates is that the information on what they cover is always rather sketchy. It can be a bit of a gamble on whether it will help you or not.
-
OK, just an update.
Today I switched off my PC, then booted it again and nothing came on the screen, it wouldn't get in the BIOS and it just did one long beep and two short beeps.
I had to let it for 2-3 minutes in order to let me get in the BIOS. After that it booted normally.
Either there is something terribly wrong with the BIOS or my motherboard is dying.
Please, if you have any suggestions I would be glad to hear before I return the motherboard.
Thank you
-
One long and two short beeps means the graphics card or monitor is a problem. It might be worth reseating the graphics card and checking the power conmnections on it.
-
Jut wanted to update you guys:
I went my motherboard for replacement. They replaced it with a new UD5 and guess what: Problem still there even with the brand new motherboard.
Next in line is checking the CPU. :(
-
As a matter of interest what PSU are you using?
-
Hey Dark Mantis,
I am using a Corsair 750 Watt PSU which has very good efficiency.
I am really starting to believe that there is something wrong with the UD5 motherboards as a model, like they cannot work out big amounts of RAM. It is really strange that a second motherboard exhibits the same exact problem. On Monday the service department will have another new UD5 delivered as well as a new CPU, if the problem persists there is no doubt that there is indeed something wrong and I am afraid I will have to change the motherboard model.
I spent two weeks trying to figure out what is wrong with my MOBO trying all kinds of BIOS settings I could find in this forum and other sources and now it seems that there is something else going wrong.

Well I think we can discount the PSU as the problem area. I don't really think that the UD5 has a problem with large amounts of RAM though as there are others running large amounts and I haven't heard anyone complaining of this problem. The UD5 is basically the same as the UD7 and UD9 and they definitely work ok. Please keep us informed of your progress with the new board and CPU.
-
I certainly will, unfortunately I won't be having my PC until Monday, but I hope that the problem will be shorted with the new UD5 board. I will report back!
-
Just one quick question:
In case the service department replaces my UD5 with a UD7 or UD3 will I be forced to perform an Windows 7 format and re-install? Or will I be able to keep the same OS given that these motherboards have more or less the same components?
Thank you!
-
No even a change of motherboard for the same model will be picked up by Windows as a change of hardware and you will have to reactivate the OS again. You will probably be able to get away with actually having to reinstall it though.

Ηmmm...reactivating is not so much of a hassle, re-installing will certainly be a job that will take me approximately 2 weeks to do. I am ok with reactivating windows, what concerns me is whether the OS and the programs will work correctly and that all the devices will function as well.
-
If you sent away a UD5 that should be what is returned (otherwise I'm sending my UD7 back for a UD9 ;D). If so there shouldn't be any difference in the chipset or other devices onboard. As long as your peripherals are the same you shouldn't have any problems.

I know, but I was told that UD5 was out of stock so there may be a replacement with another equivalent motherboard ;D. They tried with another brand new UD5 but it had the same behavior. I don't know what to think. Let's see...
-
I expect if the original UD5 is out of stock they will replace it with a GA-X58A-UD5 instead. Basically the same board just a bit upgraded.
-
Well, right now all the X58 motherboards are out of stock. I'll most probably get a UD3R because it is in the same price range as the UD5.
-
Personally I would hold out for the same spec which would be the GA-X58A-UD5 ;)
-

Why is that? As far as I can see in the specs, the only difference between the two is that the UD3R suports SLI / Triple SLI whereas UD5 supports only SLI. All the other specs look identical. Am I missing something?
-
Both boards specifications are almost identical apart from the fact that the UD5 is slightly better built. They both will accept triple SLI/Crossfire setups, have the same number of USB ports etc.
-
Is it something critical then? In what aspects is it slightly better built. The most possible replacement will be a UD3R that's why I am asking.
-
Nothing to worry about. The heatpipe cooling is a bit better on the UD5, that type of thing.
