As title, I notice against certain background these very subtle green dots flashing on and off (but only against certain backrgounds) and they seem to dissapear after a shortwhile.

I have unlocked my 6950's shaders only. Do you think I should revert back to the the original? Or could this be something else? (I heard it could be DVI cable cross talk? But Ive never had this issue with my previous 5770s).
 
Try different cables if possible but artifacts on screen are vRAM related in my experiance. Have you oc'd the memory? What are your temps like?
 
I would try reverting back to the original state of the card just to see if it vanishes, although artifacting as far as I know is usually related to dodgy memory on the card.
 
Admittedly they are very subtle green dots which usually disappear after a while.
When you say dodgy memory, does it mean that it is grounds for RMA?
I think I was getting these even at standard clocks. But I have to double check.
 
Yeah if the memory is faulty causing artifacts then it's a deffo RMA.

I've had this on two previous cards, although they were visible in the BIOS on boot aswell as on the desktop.

Sometimes underclocking can help remove them, but that defeats the purpose of owning a high end card.
 
Have there been cases of such artefacts appearing due to flashing the bios?

Do you think I should perhaps order another one? Perhaps a Saphire?

Well I got them on a Sapphire without even unlocking/flashing it. Have just RMAed it. It would happen after the card had been under load for a bit and I returned to the desktop.
 
Ooh thanks for th info Operation.
Can I ask what you will use in the meantime while its being RMA-d? Did you describe the fault as such? Or could you demand a replacement or refund?
 
I have a spare 4350 that I am using while I am waiting. Obviously , I'm not gaming gaming :)

I sent my initial query in a webnote and they asked me to reproduce the issue using heaven benchmark, msi Kombuster and a couple of others I can't recall, and to report back. Apparently the suppliers don't respond well to faults reported in games, only benchmarks. I followed it up with a phone call explaining that after a period of load, when I returned to the desktop there were small green an red 'artifacts' appearing randomly around the screen. They asked me whether I was looking for a refund or replacement, I said replacement and they gave me an RMA number and email instructions for the return.

I wasn't asked about flashing/modding, but if I were you I'd get everything to factory settings first :)
 
Tbh, after loading this thing with 3dmark vantage, 11 and heaven benchmark (I wasnt sure about using Furmark as Ive heard some horror stories?), everything seems to be running well and no crashes or green artifacts.

Ill leave it be for a week or so and see how it goes :)

In the meantime, Shogun 2 and Crysis 2 awaits! :)
(As well as some Monkey Island 2 special edition for some GPU stress free activity :D)
 
Ok, but it happened for a reason, and that reason is still there. I would at least restore the bios to default if you're going to keep using it.
 
Hi folks.

I noticed these green pixels flashing against the blue background of the OCUK forums just after booting up my rig. And after about 5 minutes theyre now completely gone.
(And yes I have flashed my card back to the original bios just incase).

Idle GPU temperatures are around 39C atm. What should I look out for to try and solve this? Could it be drivers? Some bios setting? Any insight or input would be greatly appreciated!
 
i had the same issue with mine also, this is a vanilla asus 6950 OC, unflashed.

i would get coloured artifacting on the desktop (most of the time in 2d mode only) but then sometimes when i went to play fallout new vegas, i would get some crazy lighting errors. tried reseating the card and problem gone!. for the moment.. tho i am a bit nervous about the card now...
 
Hmm thanks for your feedback Aikon.
Tbh, so far so good. But like you, in the back of my mind Im a bit nervous.
I never get any crazy lighting errors in 3D games. Playing lots of Crysis 2 lately and no problems whatsoever. Its only the odd time I would notice it in browsing.

Oh and also, I noticed it while W7 was booting up (the flashing windows logo), little green dots would flicker on and off around it, but again I only saw that once, and not sure what to make of it (and whether I should exercise my right to RMA...).
 
I had a few green artifacts that would randomly appear and as mentioned after quittng out of a game. But since I have changed my Psu I have not had them ? My old Psu was a TX650 and my new is a Cooler master 700w gold. The TX died completely so it could well have been the faulty psu causing the problem.. ?
 
That very interesting. I RMA'd my 6950 because of little green artifacts like these but it's being sent back to me as not faulty. A psu upgrade was all I could think of as an explanation so I've ordered a nice psu. That's given me some confidence that it might fix the problem.

The TX650 that I had should have easilly powered two 6950's, I think it was due to the fact mine was faulty and dying..

I have also read that the cards can take a bit of running in ? Seems weird to me but a lot of people have reported the cards to do this at first but then it clears up after time. :confused:
