Stable overclock but bf3 crashes???

rupok93 · Sep 17, 2013

I overclocked to + 200 mhz core and +275 memory on my 660ti. I tested stability with msi kombustor and it seems to be fine with temps reaching max 67C under load. However when I go and play bf3 it crashes to desktop after a few minutes with the message

"DirectX function
"GetDeviceRemovedReason" failed with
DXGI_ERROR_DEVICE_HUNG: Device hung due to badly formed
commands.. GPU: "NVIDIA GeForce GTX 660 Ti "

Now I am wondering if this means my overclock isn't stable or if its just the game can't handle my overclock or something.

Please help. Thanks

what's your PSU, how much extra voltage do you have going to the 660

It might not be stable. Its kind of like if your car was good in a straight line but couldnt turn.

Same idea. It might be able to run Kombustor until the day it dies, but the mixed load of the game might take a toll.

just means your oc isn't stable... benchmarks and stress tests are insufficient to determine the stability of an overclock- gotta play games to figure that out

Try bringing down your memory clock a bit, in most cases that can be your main problem.

Darren Kitchin :

PSU is 700 watts I don't think thats the issue.

Ill try and bring down memory clock and see if that helps as Hyaku suggested.

How did it go?

Hyaku :

Ya didn't workout unfortunately. The max I can seem to go is at +165 core and +263 memory.
at 105% power target. You think raising power target to max (123%) will help stabilize the overclock?

rupok93 :

When I overclocked my GPU, I maxed out my power target and core, then slowly brought up my memory till it crashed, then put my mem down by 25 . After that I brought my power down till it it started to crash. right now I have mine at +109%. I believe you said you have a 660ti, I think it's default clock is 900 something... Try setting the clock to ~1000 and slowly bring up the mem clock from default till it crashes on about +120% power.If it crashed right away bring down the clock a tiny bit (~25), sometimes overclocking is tedious, it took me 2 days to find a perfectly stable oc for my card.

Sorry it took me so long to get back to you, I had a few errands to run.

overclock one clock at a time... keep your memory at stock and find your max stable core overclock, then you can try overclocking the memory

If you do both at once, you have no way to know what the problem is.
