new asus 660 ti crashing

[dragantoe]

I just got a second 660 ti to run in sli and whenever I play certain games, or whenever the gpu is under heavy load for a long duration, the drivers will crash and go back to the game then repeat every few seconds until the whole system freezes. I've tried a lot of different things, but I'm pretty sure it's defective, however I want to see if anyone else knew what to do before I send it back.

what I've tried and failed;
-reinstalling os
-disable sli
-use only asus card
-updating bios
-use different pci-e slot
-uninstalling nvidia audio drivers (some people said this works)
-using older drivers
-underclocking the gpu

Have you run other sli setups on the same mb?

Have you tried running the card in another machine? At times there can be rare cases of GPUs just not working well with other components, motherboards esp.

asus mobo + gpu not working together? not likely but I'll try a different machine

no, but the asus card doesnt work by itself either

I think it is defective. My hd 7770 did the same thing before it died.

Make and model of your rig's power supply?

I would try dialing back your o/c and lowering you ram speed and loosening the timings. You can probably save your current settings in bios under a profile making it easy to go back.
More gpu power often exposes memory errors in my experience.

edit: I reread and see you have tried running one card again, and the new card alone is causing trouble when the other does not, alone. That can surely point to a defective card also.

I missed that. Yes, it certainly sounds like a defective card. Return it ASAP.
