Hi all, Once in a few months time my PC freezes while gaming. The only thing I can do is reset my PC using the reset button. My PC then gives me a BSOD when starting up, I don't even get into Windows. The BSOD says something with 'atikmdag.sys'. The only thing that seems to repair this is reinstalling my whole PC, which is of course a lot of work. Fixes like this one don't seem to do the thing for me: http://forums.guru3d.com/showthread.php?t=363233 I also tried booting in safe mode (which works), and then run DDU (the latest version). This also does not seem to fix it. This has happened a few times already, once every half year or so.. I had this problem with Windows 8.1 and now with Windows 10. Are there any guru's that can help me find a way to fix this BSOD without reinstalling my whole Windows?
it's going to take months to figure out if anything fixes it.... troubleshooting it could take decades. Need to find a way to reproduce it faster, and without the corruption that seems to be happening when it does. I think maybe totally disabling windows write cache, and doing a disk image with something like macrium reflect, they have a free version, could save you a lot of headaches at least while you are trying to figure all this out. After doing all that... maybe start with downclocking the gpu core and ram a slight amount would be my first thing to try. Just feels that way to me.
Ha, no you wouldn't think so. I downed memory on mine, about 20mhz, in the card's bios. Too many strange things going on at one time and i wanted to rule it out. Since i lost no fps, i just left it like that since. Rather be safe. I don't trust video card components at all, seen too many just burn out out of nowhere and do things that make absolutely no sense. EDIT: also being on crossfire? A whole nother thing... have you disabled ULPS? Test 1 card at a time etc. One could be just slightly off.
I formatted and reinstalled Windows 10. So the dump file is not available for me anymore. But thx anyways!
I'll have to check this out when I get home. How do I enable or disable this? In the BIOS, or in Windows? EDIT - I can see on the internet that I need to edit my registry for this? Is there any way to disable this in the Windows UI or AMD driver or something?
No option in the UI but you could either edit the registry manually or use software to do it for you like http://forums.guru3d.com/showthread.php?t=403389 Find EnableUlps and right click, set new value -> 0. Either restart the driver or reboot for changes to take effect.
And this maybe can fix this issue I am having? If I am right, ULPS is only enabled when I am not gaming. This issue occurs only while I am gaming.
Might as well disable it, it's kind of redundant and has been known to cause issues. It's a bit of an extreme measure to save power, especially for a desktop, as the cards will save plenty from their own power states. Sure in a world of perfect drivers it shouldn't make a difference but.... lol AMD. Just use oneofgod's tool, its make it a lot easier and has many more tweaks in it in case you want to try something. I found it handy to keep around.
I have had that error with my trifire and it turned out to be bad stick of ram that only showed itself during gaming. Found that out with Intel Burn In test, it runs processor and ram thru 10 cycles and if it makes it thru that you can eliminate processor and ram as the problem. http://www.xtremesystems.org/forums...-IntelBurnTest-The-new-stress-testing-program BaNsHiE
Another thing... re-seat all ram, GPU cards, and and sata connections-->both ends. I've had RARE times where, even though those things were seated perfectly, this did the trick. Just another base to cover.
you probably know this already. http://support.amd.com/en-us/kb-art...TIKMDAGhasstoppedrespondingerrormessages.aspx
Could this be an IRQ issue? Is your NIC sharing it's IRQ with your GPU? It can happen, especially if the NIC is using a PCI-e lane (I've seen it happen before, but usually occurs with other expansion cards such as sound cards).
