Graphics card failing

[xastxast]

Hi guys,
During the game suddenly some dots appeared on the screen(look attachment I can't explain)then returned desktop everything is fine no dots temperature is normal.When I enter any game those dots appear.There is no overclocking what maybe the problem.XFX 6870 600 watt psu.

Did you update the drivers recently?

 

[xastxast]

Yes even beta

 

[The_Golden_Man]

Try underclocking the card.

 

[xastxast]

I did no change

 

[SocalMark]

Wow that's how my x800 card died.

 

[The_Golden_Man]

I did no change

Well, I'm not going to tell you to put it in the oven.

 

[Greenlepricon]

Yep that's what I was hoping wasn't the problem. Try reinstalling it from the beginning maybe? I hate saying that you might need a new card

 

[xastxast]

Well, I'm not going to tell you to put it in the oven.

You say the problem is that serious before oven I'll clean up the case let's see what will happen.

You should also try the card in another system, in order to be sure it's the card.

 

[xastxast]

I'll install ubuntu to see operating system drivers etc is the problem.But everything is fine besides games.

 

[Greenlepricon]

I second trying another computer. Also if you have another pci slot you can try that (probably won't be the problem)

 

[xastxast]

I installed ubuntu opened a simple 3d game ,there were dots. Cleaned the graphics card applied thermal paste again problem not solved.This only happens in 3d games there is no problem in desktop ,video .I'll buy another card.

bad vram imo

bad vram imo

İs this a fixeble thing?

 

[amenx]

I dont know what it is about crysis that damages vram but same happened to my 7900gt years ago. Also saw dots at post before booting into windows, a sure sign the card was gone. Have heard others experiencing same after playing crysis too. Will wipe the game off my drive, lost interest in it years ago.

If you have access to ram chips and are good in micro-soldering.

These are rendering artefacts, specifically random dots or checkerboard patterns of incorrect colour information suggest bad vRAM on the video card, usually because the vRAM is overheating.

Ideally you need to post a graph of temperatures for the video card during full load so we can see if they're out of range or not. High temps would suggest bad or broken cooling, if the temps are normal then the vRAM might have permanent damage and you'll need to RMA the card (if its within warranty).

I am busy right now ,buying a new one is more practical.

I took out the card but the temparature was normal between 45-62 celcius.I installed a cooler so the warranty is void.Overheating may not be the issue because card was cooled fine I didnt see over 62celcius.

 

[xastxast]

Also there were heatsinks above rams ,arctic cooling accelero and 2x 12cm fans.

Is this 62C under peak load? Is that the temp of the GPU or the vRAM or ambient?

If you modded with a custom heatsink it's possible you have a bad contact between your vRAM chips and the heatsink, either a gap so no contact, or too much thermal paste applied, or air bubbles in the thermal paste.

62C seems very low for a LOAD temp for either RAM or GPU, are you sure that's under full load?

 

[xastxast]

62C is the maximum number shown by msi afterburner during the game it's the gpu temperature.It may not be the full load but its the temperature after 1 hour of game.I have no idea about the vram temperature.I applied thermal paste again didnt change but now I am removing the heatsinks from vram chips ,one of them is close contact to the pipe it may be the problem.I am using like this about a year.

 

[xastxast]

Above I mean ,top of one heatsink is very close or touching the heat pipe ,will it be the problem?

XFX make sh*ty cards.. simple as.
They just cut to many corners = short lived cards.
