Purchased (new) a day ago, it's artifacting and rebooting :(

Installed with the appropriate precautions i.e. static strap and making sure the card is seated and not touching any capacitors etc, fresh Win 10 installation with latest drivers. Output is via HDMI to Samsung monitor which was fine with a R290/1080, I've tested it on my HDTV and it's no different.

I've tried various display modes, swapped cables (both twin 8pin power and the HDMI) switched which power rail is used for the twin eight pin power cables etc etc. I've tried the different bios settings too, the only thing i can see is that there is a row of LEDs on the back of the card (above the LED logo on the cooler) as as you look at it in situ and the last to the left but one is lit? - see picture.

I've no idea what this means as the documentation is woeful :( Cooling fans are working.

Specs are Asus sabertooth Z87, 4770k, 1300w EVGA psu that can handle quadfire/sli so that shouldn't be the issue.


Stumped! Apart from a duff psu that springs to mind I've rarely had an issue with hardware, certainly never with new stuff.

That looks like a GPU ram issue, a hardware problem that I doubt will be correctable..

Have you tried a different HDMI cable, or swap to a DP cable? Have you got a different monitor to try? Does it do it in the motherboard bios screen?

If you still get the irregular pattern in the motherboard bios screen then, and it's the same with different cables and alternate monitors then it looks like an RMA job if you've tried all that unfortunately.
 
Unfortunately it's a yes to all those questions. I've taken a screenshot with print screen and the issue is still there. I've now put my R290 back in = no problems, in fact I'm posting via my desktop now :(

Classic failed memory symptoms. If you have another PC to test it in and it does the same, that would be the definite confirmation the card is faulty, but I would send it back for RMA.
 
The row of LEDs on the back is a GPU meter, it lights up an LED for every 10% of GPU utilisation in game. Doesn't signify any faults.

Anyway, that's duff. Send it back.
 
Thanks.

I forgot to mention I have the latest motherboard bios installed too and the pcie slots are version 3.0, tried it in both but still the same :/. I was hoping I'd made some sort of oversight but I have built pcs for over 20 years now, so I generally know what I'm doing for the most part.
 
with vega being in such high demand i think they are really pushing the worse bins out that wouldnt normally passs QA. the oc headroom on most cards now is tiny and i have seen a few barely being able to run stock settings.
 
I wonder if these faults don't affect mining, so they're just hoping the cards are purchased by miners rather than gamers..?
