Quick question

Sapphire 6850, OC'd to 890 / 1090 stock voltage, stable for a year now. Temps never exceed 65C, I run fan manually at 65%.

This time however, decided to set fan to "auto", in the interest of reducing fan noise. Now when gaming, GPU artifacts after a while. However, completely normal operation with OCCT and Furmark, no artifacting.

Further details: GPU peaks at 70C during gameplay, it seems to only start artifacting when I hit the 72C mark. When stress-testing with OCCT or Furmark, GPU goes to 80C, no problems, no errors, no artifacting. Running Catalyst 14.3 Beta V1.0.

I'm annoyed. So what's going on?

doesn't really help, but I've had similar things happen with my 7870 CF setup. When gaming, everything is fine for first hr, but after that is starts to artifact when I turn quickly. if I exit game, even chrome flickers and artifacts until I reset my PC. after reboot I can stress test with no artifacts.
same here with temps being is safe zone and multiple benches still don't show artifacts (benched 3dmark and heaven several times back to back with no problems).
only difference I see is that my VRM is going to steady 50 which before it usually got to 45ish. going to redo my fan curve and adjust the angle of my fans on VRM to see if that possibly helps.

Like I said, both OCCT and Furmark are stable after 1 hour of testing, using my overclocked settings.

Yes, by which you mean the "error check" box? I have that enabled to check for errors. If I set my clocks too high, yes it will tell me I'm getting errors. At stock and my current overclocked settings though, no errors after 1 hour of testing, with temperatures of around 85 C.

As long as I don't reach 72 C while gaming, I don't run into any artifacting or GPU crashing problems. The last time it reached 72 C though while playing Skyrim, the GPU started artifacting, followed by a BSOD.

I think I'll change drivers. I'm currently running the latest 14.3 Beta V1.0. Do I simply uninstall these drivers and install the official ones? Or is there a more complicated process to it than that?

EDIT: The last time I uninstalled drivers to update to newer version, the uninstall process removed my USB and LAN drivers... how can I avoid that?

I think I found my problem. It seems to be something to do with RadeonPro. The games don't seem to like that I set my GPU clock speeds in RadeonPro and allow MSI Afterburner to control my fan speed. I'll do further testing to confirm this.

EDIT:

Interesting, I tested again and it confirms my hypothesis. Setting clocks in RadeonPro and allowing MSI Afterburner to control fan and display FPS, artifacts minutes into the game.

When I set my clocks in MSI Afterburner instead, no problems... bummer, I guess I have to use one program or the other, but not both at the same time. Still, very relieved its not a hardware problem.

EDIT:

If anyone else is having the same problem, it is specifically caused by enabling Overdrive in RadeonPro.
