GTX 680 overclock causing BF3 crashes

[HashFail]

While overclocking my GTX 680, I pushed it to 1250mhz on the core using GPU Tweak. I tested it in furmark, and, getting no artifacts, decided to test it in BF3. After a few minutes of gameplay, I got a DX11 error and the game crashed. At first I thought it might be due to the new 310.33 drivers or my FXAA injector, but after ruling those out, I figured out it was caused by the overclock. I found the highest stable clock to be 1230mhz on the core. I was just wondering if anyone knew how I might fix this, since BF3 seems to be only thing affected by the higher clock and I've heard of 680's going higher. It's not overheating (never tops 55) and I'm not increasing the power target, the voltage, or the memory clock. Not sure if doing any of these things would help, I'm new to overclocking.

My rig:
CPU: i5 3570K (stock clocks)
GPU: GTX 680
Motherboard: ASUS Maximus V Gene
PSU: Antec HCG-900 (900w)
RAM: 8GB G.Skill Sniper (2x4GB, @2133mhz)

Which GTX680 do you have? Out of the box, the Asus DCII TOP is not going too much higher either...

If you didn't played yet with the core voltage, I think, it would be the time to start... push it to the max, it supposed to be 1.175, then reapply the OC on the core...

That is your VGA max. It is pretty good and I would not be too worried about it.

All of those will help ;)...particularly the voltage. 1230 is pretty good entirely stock. just push the voltage a bit and increase the clocks a bit too and see what temperatures you get....below 70 is all good...some don't mind low 80s....but I would not go there...not for long anyway.

Yes I agree. Your overclocking is fine, to play BF3 you have to increase the voltage a bit. I have the GTX 560ti and I have to set the voltage to 1.037v to play the game without crashes.

hey guys,

im in the same state as the OP. increased the core voltage to 100% this seems to let me bring a more stable over clock. though after playing 30 mins of bf3 game didnt respond so i guess i have to lower the clock speed. but just confirming if this is safe to adjust the core volt to 100%, max i see is 1.175 volts and even with the core voltage set to 100% it wouldnt go above 1.175 but my GPU-z says a different story... 1.5 ? im paranoid now.

Wow! What resolutions are you guys running on BF3 lol? A GTX 680 is already a heavy duty card. Do you really need to OC it lol?

Anyways, back on topic. nomadVP, you should decrease your OC a little. Remember Kepler starts throttling at 70C then 80C, then 85C and lastly at 95C. In your GPU-Z screenshot, it's already at 78C and your fan is at its max. 😛

Lol I'm running on a big 46inch LED tv @1080p, can't remember the exact resolution but its nice to overclock ! Yeah I adjusted my fans to 100% that's why. Anyways.... Back on topic my real question is about the voltage. Should it be on 100% and is it fine ?

[HiVizMan]

It makes no difference if your tv or monitor is 40" or 108" 1080p is 1920 x 1080. A 680 will max out the eye candy and not stress to hard doing it.

I just wanna know if its safe on 100%
