5850 Display Driver Problems

Hi there,

I've been having problems with my display driver not responding (Event Log says amdkmdap) and some random colour screen within minutes of anything 3D happening. It started happening when I updated to Catalyst 11.6 when they first got released, and after doing a complete format and re-installing 11.5 everything was fine for a bit but it has now started happening again. I've tried updating to 11.7 but that hasn't fixed anything - and yes I have tried the uninstall, safe mode, reinstall thing as well as checking for ghost devices.

Running OCCT or Furmark causes the driver to stop responding usually within 1 minute and games do the same within a couple of minutes.
I did have some overclocks on but even resetting to default settings (and even dropping the memory down to 1333 from 1600) doesn't seem to change anything. Currently running memtest86+ on my RAM but I left MemTest running on it over night and didn't get any errors.

My system:

PSU: Antec TruePower Trio 550W
Mobo: MSI 790FX-GD70
CPU: Phenom II 955BE
RAM: OCZ3P1600LVAM4GK 7-7-7-24 1T (also tried 1333 7-7-7-24 1T)
GPU: MSI 5850 Twin Frozr II
OS: Windows 7 64-bit

Temps are around 40 degrees idle for CPU/Mobo, GPU barely gets to 60 degrees before the display driver crashes.

I've done a fair bit of searching for people in similar situations - I saw there was some amdkmdap crash related to 2D flash players and such but that's not applicable here.

My next step once memtest86+ has finished is probably to drop the card in to an XP machine and see if I get any issues there. It does seem to be Win 7 64-bit related a lot of the time from other people in similar positions.

Any suggestions?


Cheers.
 
Is your CPU overclocked ? If it is you may need to redo the overclock and check the memory voltages and cpu voltages are fine. Also check your PSU and see if it is giving the correct voltages when it's under full load. I woudl set everything back to stock settings and maybe even load up the safe settings in the motherboard BIOS and maybe check if their is a new BIOS for the motherboard while you are at it and same for the graphics card.
 
Everything is back to stock speeds and voltages. I can't seem to find my multimeter to test the PSU voltages properly but the rails seem to be within 5% through the BIOS. The mobo BIOS is also up to date.
3 hours of Memtest86+ didn't find any errors as I expected really.

Seems likely that this is a driver issue rather than hardware related but going to unplug all the unnecessary components to see if the PSU is struggling and will otherwise try a completely different PSU.
 
Sorry, I meant the OCCT - GPU test essentially the Furmark equivalent. Will try running HWMonitor at the same time as the bench to see if there's a huge voltage drop.

Edit: Just ran the OCCT GPU test with Speedfan, HWMonitor and Afterburner monitoring various voltages. +3.3V drops to 3.2 minimum, and is usually 3.22V idle. +12V is reported at 12.06V by Speedfan and 12.14V by HWMonitor and doesn't really fluctuate from that at all. Got a complete reboot this time instead of the more usual driver stopped responding. Voltages seem fine I think.

Try installing 10.10 drivers & if it still does it then its not the drivers.

As far as amdkmdap & driver stop responding then there is likely very few PC gamers who have never had it.
 
The 10.10 drivers seem to be doing the same thing, though without completely reinstalling Windows again I can't be 100% sure there isn't something left over. Guess I'll try putting the card in a different machine and see if the problem persists.
