    Default X48-DQ6 having ati2dvag errors and infinate loops

    Getting ati2dvag errors when I try to play games. The computer either hangs, resets or the monitor goes into standby mode for a bit before it drops out to windows. Once there its in the most basic resolution with the most basic colours and a pop up says the ati2dvag has stopped working normally and that I need to reset pc. And when I checked the event viewer it says its getting stuck in an infinate loop.

    Built the system 2 days ago..only changed 3 components from the previous build. Motherboard, cpu and ram. All brand new. And I set windows up identical to how it was on the previous build. Was a completely fresh install of everything with no errors. So I know there must be an issue between the mobo and the gpu. I've tried deleting the ati drivers and booting to safe mode and completely cleaning them out with Driver Cleaner Pro. Then only installing the driver without the Catalyst Control Center. I've tried turning the hardware acceleration down. I've tried turning write combining off. And I've gone through bios to make sure everything is at standard settings. And I updated everything with windows update. I'm at a loss.

    System is as follows:

    OS: Windows XP Pro SP3 (+ I installed netframework 1.1, 2.0 and 3.0)
    Processor: Core 2 duo E8400
    RAM: 2Gig Dominator PC8500
    Motherboard: GA-X48-DQ6 (Rev 1.3)
    Graphics card: Sapphire HD4770 (using catalyst 9.7 driver)
    PSU: Silverstone ELEMENT 500W

    Everything is at its standard settings. No overclocks or voltage tweaks or anything. Any help would be greatly appreciated. I don't want to have to send the mobo back for a refund if at all possible.

    This can be caused by many things. I would go ahead and install the latest drivers first

    Then can you please check to be sure your card is not overheating.

    What BIOS version are you using on your board? I do recommend you update to the latest one if you are not using it now. F8e is posted here >>>

    Please use Qflash to update your BIOS, not @BIOS. Here is a guide

    As for your settings, did you make any adjustments for your ram in the BIOS? If not you may need to at least set your ram voltage manually to the specified amount. That's only 2GB you have right? Just checking

    Yup only 2GB of ram. Ah I think the bios version is F6. I have updated everything else and the graphics card hits 60-65 C under load so its defiantly not overheating.

    I'm cool with flashing the bios but I've never touched voltages before. I went into the bios but it didn't seem to say what voltage its at now so I don't know how much I should add to get it to the 2.1 volts they can apparently take. So what should I do ? Thanks for the reply btw :)

    Your ram voltage, if spec is 2.1V would be setting of +0.3 (1.8V Default +0.3 = 2.1V)

    I'd go ahead and update your BIOS, please follow the guide so you get it all flashed safely and properly.

    Will do. I'll go check that thread just to be sure. I have flashed an asus board before but it can't hurt to be 100%

    Check back in here in a bit and let ya know how it went.

    Good luck, be sure if you are using RAID that you go back to the BIOS after loading optimized defaults and rebooting and change your settings back to RAID. Noted heavily in the guide of course.

    Voltage adjusted and bios successfully flashed. Guess now I just need to go game a bit and see what happens.

    Nice to see you had no issues!

    Post back anytime with your findings or if you need more advice on things

    Thank you. Its always a little worrying flashing the bios but it went flawlessly. Unfortunately its made not a bit of difference. Still getting the same errors. They happen in windows environment too. Just takes longer to happen. In game though it usually happens in the first couple of minutes.

    Since I made the original post I did a fresh install onto a different HD just to rule out a bad install or a dodgy HD. I also only installed the bare essentials and left out SP3. That also made no difference what-so-ever. I'm stumped.

    Edit: Oh the temps on my graphics card were actually from a really hot night so I checked again while gaming and they were only 54C. Pretty damn good.

    These kind of errors can occur either from excessive heat (not an issue with your temps) or an unstable clock speed on either GPU or VRAM. Have you used Overdrive to overclock the graphics card? If so I'd recommend backing off by 10MHz on each setting and try running some more games. If the issue doesn't occur, raise clocks until it does, then lower by 3-4MHZ for a little safety margin.

    If you have everything at stock, I'd try un-installing the ATI driver suite, then manually cleaning out the /system32/drivers folder and registry while in safe mode. Then install the latest drivers. The 9.8 catalyst suite has been released on an ATI employee's blog as a "treat" for his readers. he confirms they are the final, complete drivers. They're not on the official AMD download page yet, so here's the link: What?s a good title for a Quakecon blog? | AMD at Play the drivers are just above the comments at the end of the blog.

    If you still have the problem, try lowering clocks down slightly from stock. This may sound strange, but it may help diagnose the problem. I'd say if it stabilises on lower clocks, there could be a quality issue with the card. The 4770 is the first ATI card to use a smaller manufacturing process, and there have been some problems with it both in terms of ATI getting poor yields (lots of non functioning chips, ie wastage) and in terms of end users having problems. Signal leakage could be an issue if the new GPU isn't shielded well enough for example (usually done with more transistors around the edge of the die, actually on the die not external). ATI added such measures to the 4890's GPU to enable higher clocks than it's previous 4870.
