RTX2060 strange behaviour

[Daan._official]

Bought a faulty RTX2060 to see if I can fix it and give it to a friend to upgrade from his RX580. Seller said it has artifacts and crashes, but doesn't have any technical knowledge to fix the issue so he just bought another card.

 

I take it home and put it in and indeed in my rig it has artifacts too. I opened it up, repasted and took air dust cleaner to take out some dust. Put it back in and as soon as I download Geforce Experience and install the driver they disappear. I run some tests (Superposition and a few games) and it seems to be fine but it runs quite hot (83 celsius) and at a clock speed it's not advertised at (+-1900 @ 1050 mV). I try to bring down the clocks and also the voltage a bit and it crashes. 

 

As soon as I restart the artifacts are back and the driver is uninstalled. Basically rinse and repeat with some tweaks (i.e. disabling some automatic updates, ran memtest and it was fine) few times to see if it makes any changes. I got the driver to stay installed but it stil keeps crashing even when not under load. But occasionally it also runs fine. 

 

I know it's the card and not my rig because I run both my old RX580 and 2080Ti just fine with it. 

 

Does anyone have any suggestions about what it can be? I already contacted Nvidia an another forum and tried some things like checking the vBios but all seems to be as it should be. Maybe just a faulty card but something tells me that's not the case. 

 

 

 

I opened it up and with spray can dusted out

i was thinking about the vbios too, i don't really know what "checking" you did to it but imo a reflash is a good point to start. Although artifacting is most commonly connected to vram instability/failure so other than increasing the vram voltage (if i remember correctly its possible on the 580) and dialing back the clockspeed a bit, you won't be able to do much else

There are tools/bootable USB stick images which check the VRAM and can indicate which of the RAM ICs is faulty. Next step would be removing it, reballing and soldering it on again.

The solder joints of the core can also be problematic but that's harder to fix.

Could also be a different issue.
