• Tried on Windows 7 and now having same issue on a fresh installation Windows 8.1.
• Update motherboard BIOS from F5 to F7 and tried beta BIOS F8b.
• Disabled the iGPU and uninstalled Intel drivers for it.
• Tested with another power supply (XFX 750W
• All drivers and windows updates done.

Included a couple of videos and a screen shot. Usually get artefacts a split second before application crashes or system completely freezes. Sorry for the poor quality phone camera pic but I can't do a screen capture at the system become unresponsive.










Tried the GTX in a different PCI-E slot and connected to TV via HDMI. Still crashes.



CPU prime95 stable @ stock.



Memtest86 9hours without errors.



Intel HD4600 iGPU runs benchmark and games fine without crashing or freezing etc.

At a loss as to what else it could be, would it be a pretty safe to bet on the GPU?

Re: Faulty Gigabyte GTX 680?

Have you tried underclocking your card to the stock 680 specs of - Base Clock: 1006MHz and Boost Clock: 1058MHz? You can use MSI Afterburner or EVGA Precision X to do it with. After that, try running Valley and BF3 again. There's been 3 revisions to the graphics card. If this test works or doesn't, you'll need to follow the steps here to get a replacement.

Re: Faulty Gigabyte GTX 680?

Sorry I should have been more specific. This card is this one, "GV-N680OC-2GD" and is running at completely stock speeds for this particular card. I've not tried to downclock it. I've emailed Gigabyte UK support so I await their reply. I'm pretty sure it is the gpu. Tried BF3 again and I get a crash to desktop and it reports a DirectX error. From reading around the Internet seema its a fairly common error with quite a few people reporting it as a result of a faulty gpu.

Re: Faulty Gigabyte GTX 680?

Thanks. Just tried the onboard. Completely fine after several runs of Ungine Heaven. See op for screen shot.

Even tried via HDMI instead of DVI on my TV screen with the 680 and issue remains and tried the second PCI-E slot too. Have raised a Gigabyte Support Ticket.

Re: Faulty Gigabyte GTX 680?

Yeah I hope so. Got a reply from Gigabyte asking me to try a couple of things like updating the BIOS and building the system outside of the. Have been trying to get hold of my ex-colleague who bought it too just in case it needs to go back to the retailer but no luck so far. Have a copy of the receipt but I hope I'll be able to RMA it directly back to Gigabyte tbh.

yh you should be fine,think they go off the serial number on the gpu,
