Artefacts on GTX 660 SC

Fresh windows install and several driver versions - still getting tonns of artefacts on the card ( only in windows , not in bios) so i am assuming its the driver problem?

running OC stress test on gpu crashes the driver and cannot continue

You can fiddle with the driver but it looks like the GPUs memory is faulty. I would RMA it if you can.

Hello,

A few things come to the top of my head when I see your issue. First does your card require a 6 pin adapter? I looked up your card and it appears it does - did you make sure it's seated correctly in your PCI E slot? If a 6 pin is already plugged in can you try a different 6 pin from the one you are using?

Is it possible to try that GPU in another computer? Perhaps a friends computer or family member? If it doesn't work as well in another computer it may be a sign that GPU is defective.

What OS are you using?

@chainzsaw - yes it does require a 6 pin and it is connected properly and the card is sitting snug in the slot. trying different 6 pin didnt help.I dont have another computer to try the gpu at, but i tried a different gpu in the same rig and it was fine. i am running win 7 x 64

currently filed a return on the card which will take a couple of days, but still interested in what the problem might be.

skit is probably right - the memory modules are probably faulty. Well at least we know it's your GPU and nothing else

I've seen this often when the GPU memory modules are running too hot. It could be something as simple as the memory heat spreaders have inadequate contact/paste or they are just drawing too much current and are over-heating.

the card was cold at all times ( not sure if that is relevant ) . In any case i am going back to hd 6850 untill i get the replacement. thanks!

Just thought I would share an update - i sucessfully returned the faulty 660 and bought 770 instead
