Horrible Things are Happening

post #1 of 14
Thread Starter 
My Sapphire 5870 2GB Eyefinity 6 Edition graphics card is acting strange.

I can't even play Crysis 2 for more than a minute before it starts crapping its pants and freezing and showing grey screens and crashing.

My friend and I decided to take it apart (this is before it was acting up) and apply some new thermal compound on it.

It worked fine after that nothing was wrong, but I'm just throwing that in there because it possibly could be the problem.

He has the same card as I and he came over and we Crossfired our cards.

They were super buggy and such and wouldn't run anything without crashing or freezing.

After reinstalling drivers and such, it worked flawlessly.

Then more problems came when we took his out and it was doing the same thing as when we first put the two together.

After reinstalling the drivers, it worked fine again.

Until now.

Now it just refuses to play anything without going crazy.

I'm using the Catalyst 11.4 Preview Drivers with the 11.3 CAP 2 Profiles.

I am also using MSI AfterBurner 2.2.0 Beta 2.

I never get above 70C on my card under heaviest load with a custom fan profile in MSI AfterBurner.

I'm also overclocked to 900/1275, and I have made sure this is perfectly stable.

I noticed that my GPU #1-3 Temps were VERY high.

Here's a pic of when I was running Kombustor:



Are those normal temperatures?

Also, what are those temperatures for, anyways?

Thanks guys, hope you can help me.

Try bringing it back down to stock. GPU temp 3 is at 113 C. That is probably your VRMs overheating.

1st question is. What thermal paste did you use?
2nd question.Did this happen before you reapplied thermal paste?

No dust? Try putting a fan on the temporarily.

I think one of those temps are for the VRM's on your card. Those are abnormally high but can be reached by running stability programs. The card will start to throttle the clocks somewhat when the VRM's reach 125 degree's and that might be whats causing the card to crap out when playing games but that is an extreme rarity.

Those temps actually aren't the VRM's, they're separate in GPU-Z (the VRM's only get up to 60C).

The GPU temp's themselves are fine, as I said, not ever over 70C.

I used Arctic Silver 5, and I'm not sure what these temps were before applying new paste.

I think it's just the drivers messing up, because the card worked fine after we did it, it only after putting it in Crossfire and then taking it out I had these problems.

I just would like to know what temps others are getting in that area.

The temp there will climb higher too, I had it up to ~120C with minor glitching of the screen.

I just don't want to push it too far.

The inside of the card is filled with little thermal pads, so maybe one isn't making contact?

I'm going to test some more games and see if they work and what the temps get to then.

Also, the temps seem fine at idle, only in the mid-to-high 40's.

I reinstalled drivers again and it seems much more stable.

I ran FurMark stable for about 2 minutes, it wouldn't run it for more than 15 seconds before.

The temps still get really high though, and I'm not sure if they're normal.

After taking it back apart and putting it back together, I'm getting much better temps.



I'm still not sure if these are normal though.

Someone that has one of these cards, could you please check and see what your temps are for me?

I don't want to have to waste anymore thermal paste and I'll just RMA it if I have to take it apart again and it doesn't work.

According to Grunion, GPU Temp #3 is probably shader temp. You must have had bad heatsink contact with the GPU die.

Have you taken it apart yet?

Before you reseat, just make sure all 4 screws are torqued down evenly.
