480 downclocking

post #1 of 17
Thread Starter 
So, my 480 auto down clocks the core to 405 even while under 99% load folding (even at stock clocks). I went into the nvidia control panel and set the global settings to "prefer maximum performance"; however, the I am still having this problem. I am currently running the latest, 260.99, drivers, should I re-install the drivers to the earlier 260.89? Is anyone else having a similar issue?

Usually that's a sign that the card is running an unstable OC. The Nvidia drivers will automatically lower the card's clocks to maintain stability and let you do basic tasks. If the same thing occurs in game then it might be a faulty card.

Wait, lets not jump to those conclusions just yet.

Do you have Aero or any visual settings enabled on windows? If not give that a try cause sometimes without it the clocks decide to go down.

Not jumping to conclusions. Used to happen all the time to my 285s, still sometimes does happen to my 470, even with aero enabled.

Have you tried forcing 3d clocks with MSI AB?

I would if I thought it would help. But the fact that games/WUs crashed right when the clocks dropped made me certain that unstable OCs was the problem.

Yes areo is enabled.
How do you force 3d clocks in AB?

I tried a game, and there were black lines bordering all the buildings and objects. So, either the card is bad, or there was some sort of driver error.

I just re-installed with the older drivers to see if that fixes the issue.
edit:
alright, re-installed the client for this, wanted everything to be fresh.

Well if you are getting lines in games at stock clocks it is a bad card or you need to adjust the volts. Is this a SC version? Also what are the voltage at stock?
Try playing a game now with the new drivers, see if you get the same problems.

To force 3d clocks...
1. Save profile settings (#1-5)
2. Settings
3. Profiles
4. 2d/3d profile - Select the number you saved it on.
5. Press Ok.

stock voltages: 1038
I just bumped the v up to 1138 at stock to see if it would help, and it didn't.

Neither forcing the clocks.

I'm going to swap this out with my other 480 and see how that one works.

Any other ideas before I call it for this card?
