    Hello,

    I bought Q9450, GA-X48T-DQ6 and 2 x 1GB DDR3 1333 last week, and ran through the exact problem. I sent mine back but I did fix it before I sent it back. Flash your board with this bios:

    GIGABYTE GA-X48-DS5


    Should fix your problem....

    I have not been monitoring this thread as it was open in my 2nd PC.

    Thanks for posting. What Bioses are they? Are they just mirrors of the offical Gigabyte Bioses or have they been modified by none Gigabyte people?

    There are a number of Bioses on that site for the other DQ6 X48 motherboards, some of which are not on the Gigabyte website but the two Bioses on that site for the DS5 look the same as the ones on the Gigabyte website. I have not checked the files to confirm that they are identical.

    Do you have any more information on this?

    There is a new official Gigabyte Bios which was released today which makes the DES Advanced work with these motherboards. Whether that will improve anything though is open to question.

    Well after testing, I have flashed back to the previous Bios as the newest Bios was causing very high CPU usage when my PC was doing nothing. This was the same in two windows installs, one with the original DES installed and the other with the new DES Advanced. Un-installing the DES software made no difference.

    So it looks like the Bios is doing something with the CPU, maybe it is running something on an interrupt to maintain the DES feature.

    If anyone tries the new Bioses I would suggest to check the CPU usage in windows and maybe do some testing to see what performance you get before and after flashing to see if the performance is affected,

    I have flashed to the beta Bios and that seems okay, with normal CPU usage, so I will continue with that as it is meant to fix a few issues.

    According to Gigabyte memory QVL, 1066 Mhz Ram has to overcloked to 1200.

    I don't think that is strictly true. Those memory modules are rated as overclockable to 1200MHz. Gigabyte didn't test many 1066MHz modules at standard speed. The Bios does support 1066 memory running at 1066 with a 333MHz CPU and that is how I have ran it.

    However the stability did seem okay but recently it has become very poor again. With the DES Advanced software running, the CPU voltage, shown by CPU-z, was dropping to 1.05V and running only slightly higher with the frequency at full speed. This has caused regular system freezes and lock ups with a few reboots. Lock ups are the most common. I don't know what is causing it but this system is just not reliable enough as it is.

    Uninstalling DES has helped a bit, the CPU voltage is better now, without dropping very much, down to about 1.184V on a 1.2125V VID CPU. But it has not stopped the system freezing/lock ups. The 3.3V reported by Easy Tune 5 is sometimes below spec and below the manufacturers voltage tolerance. Dropping to about 3.18V when my system is overclocked to 3.5GHz. My PC froze on Saturday evening and again on Monday evening at about the same time. I will also say that my PC is powered by an APC 1500 Smart UPS but has also froze when powered from the wall socket.

    Bios settings:

    So I need some advice on what I need to do to make my system stable. What tests to perform to check it etc.

    Suggest you pull out one memory module and let it run with 2 GB and see what happens.
    This is to make sure that the board has enough power to run the ram.
    I'm using the same board and can only run 2x1GB of 1200 ram because the board hasn't got enough power to run 4.
    I've tried 4 before but the system becomes unstable even after i up the voltage. After pulling 2 out of 4, suddenly the system becomes stable regardless of the memory slot that i used.
    Never hang since then.

    If it still unstable, test you ram with memtest86.

    If your 3.3V rail is falling out of spec you can RMA the PSU as it is failing, this is not the board doing that. Not sure this would cause your issues though, but if that is correct you can RMA the PSU.


    If your Vcore is to low, just try raising it a few notches.

    Set Performance Enhance to Standard instead of Turbo, set +0.2 MCH. Then set +0.2-0.3 DDR2 Voltage, this is 2.0-2.1V, not sure what your specs are but Auto generally will only give you 1.8-1.9V

    I'm only running 2 Dimms, not 4. 2x2GB. I do have two other 1GB Dimms which are lower speed PC6400 I think they might be. Those I purchased when I was having stability problems after I first re-built with Core2 & X48-DS5. I have seen other people saying they have had problems with this board when overclocking memory but not when trying to run it at standard/default speeds.

    The 3.3Volt line is a difficult one to measure and I don't know what it is used for on this board. Under default conditions it reads 3.26-3.28 according to Gigabyte Easy Tune 5 which is the only thing I have that reports it. I only noticed it dropping when overclocked to 3.5GHz. Very few parts use 3.3 volts to my knowledge, certainly not the Gfx card, CPU, hard drives, optical drives. It's only delivered on the ATX connector.

    If your Vcore is to low, just try raising it a few notches.
    It was only low when I had DES enabled, since I uninstalled that the VCore has been within the range for my CPU.

    Set Performance Enhance to Standard instead of Turbo,
    I have already tried that but it made no difference.
    set +0.2 MCH.
    I have only tried raising that when overclocked. Why should that be necessary when running at defaults?
    Then set +0.2-0.3 DDR2 Voltage, this is 2.0-2.1V, not sure what your specs are but Auto generally will only give you 1.8-1.9V
    The memory is rated at 2.1V@1066MHz but OCZ say it can run at 2V. I have always kept it at 2V and recently in an attempt to improve stability 2.1V. I don't usually leave the Bios settings at Auto, I prefer to set them to what they are meant to be, specific voltages and timings, all except for some of the more advanced timings which I don't alter, but Refresh to ACT delay I have increased to 72 from 54 with no improvement.

    My PC locked up while I was typing the previous reply, it locks while my system is doing next to nothing and seems most stable when stressed. It also froze/locked up early this morning and on Saturday evening and I keep losing work because of it which is really beginning to annoy me.
    I did run memtestx86 v4 after it locked up this morning, I left it going for 8 passes which completed without error. I wanted to use the PC so had to stop it.

    Is there a reliable way to monitor the voltages? To check whether the PSU is delivering voltages within specification? I think this could be a voltage problem. The 12V voltage reported by Easy Tune 5 is always over 12V so that should not be a problem but it does not report the 5V line for some reason.

    There is also another problem with this motherboard. It keeps trashing my Bios settings after a system crash/freeze. If the reset button is pressed and the PC reboots it used to almost always say that there was a Bios checksum error and it would then copy the backup over the main and wipe all saved settings. I re-built the PC and even put in a minimum build but could not get it to re-create the problem. But it did later do it again but it is less common now. When it does happen it is infuriating as it means re-setting up the whole Bios and profiles. I don't know what could be causing this.

    There are so many big and small problems with this board, the clock is terribly unreliable, losing minutes a week, even after replacing the mobo battery. It seems like a board with many gremlins that passed the quality control but doesn't work correctly.

    +0.2 or above MCH is often needed for 4GB or more, this is perfectly normal and expected with all motherboards from any manufacturer.

    You may need to use the full 2.1V, some boards need it or some specific sticks out of a series may not be as good as others so it may be needed in those instances as well. The 2.1V rating only allows you to use that much under warranty, it does not always mean you will need it all, but all sticks in a series should work with that 1.8V through that amount (2.1V). So it is there for your use, if you need it, which you would have to determine by testing.

    I use Everest Ultimate to monitor voltages, you can get a trial version here
    http://forums.tweaktown.com/f69/late...y-tools-30530/

    Also in that thread is a free tool from the maker of CPU-z called HWMonitor, you can get it above or at the CPU-z site.

    I think you just need correct settings is all, it's not really a power issue at all. If you want optimal suggested settings from me please give me your current exact BIOS settings in a template and I will advise back.

    BIOS checkum errors are caused by unstable system settings, you need to get your BIOS settings correct and this wont happen.

    Clock is unreliable? You mean in your BIOS the clock looses time? If so this could also cause the above Checksum issues, this is caused by a faulty or dying CMOS Battery.

    Odd to hear a new one did not help, was it used or new? If you need a cheap place to by new ones let me know, if you are in the US, and I can link you to where I buy them.

    You may also want to update to the latest BIOS, F8c
    GA-X48-DS5 - GIGABYTE - Support&Download - Motherboard - BIOS

    If you do update, please DO NOT USE @BIOS!! Use Qflash or DOS
