6950 2GB Crashes in Battlefield 3 Ultra

[mknlb50]

Hi. I recently bought a Sapphire 6950 2GB Dirt 3 edition... Whenever I try to run BF3 in Ultra settings (AA off), the game crashes after playing for about 10 minutes or so. There's no stuttering and what not; The game runs smoothly until it just crashes with an error message showing, "Battlefield 3 has stopped working."

However, when I do set it to "High" settings, the game runs flawlessly.

Shouldn't 2GB vram be enough to not crash BF3 in ultra settings? Should I RMA my videocard?

Thanks!

[edit] I am currently using the official latest 11.10 drivers.

Are your temps / voltages in the green while playing? Even if the VRAM wouldn't be enough, it wouldn't outright crash.

I got these from AMD Overdrive while playing BF3 in window mode using the aforementioned settings:

activity: range 40%-96%
power control: 0%
avg temp: 55C
gpu and ram: stock
fan speed: 33%

They were all green if that was what you were asking. How do I check for the voltages under load?

[edit] Still crashing even after the origin update... I'm about ready to RMA this.

Using GPU-Z in-game...
GPU Load (max): 29%
GPU Temp (max):
56.5
58.5
59

VDDC: 0.900V

VDDC, is that your GPU voltage? Seems a little low, my card runs slightly higher than the reference voltage at 1.112 (reference is 1.108v). I play BF3 on the same settings at 1920x1080 and have not experienced this.

Have you tried running anything like 3dMark to see if stressing the card in general causes crashes?

 

[mknlb50]

Yep. It was the voltage. I set it to its true stock voltage @ 1.10 using sapphire trixx and now the game runs flawlessly.

Why Sapphire would set its default voltage to 0.9v is beyond me.

Thanks for pointing me in the right direction guys!

Sorry to bump, but I'm having the exact same problem, only I'm a noob and don't know how to fix it. Here is a screenshot of my trixx:

Is that what you guys talk about, when setting the voltage 1.10 or 1.12?

Here are my computer specs:

EDIT, I changed Anti-Aliasing to "Use Application Settings" in the AMD Vision Engine Control. And now I'm not having the crashing problems anymore.

The only thing now is, my Card is running at 67-69c when playing Battlefield. My fan speed is set to auto, and is generally 56%

Should I change my fan settings to a certain number. Or is auto fine?
