Is My GPU Bad??? DEAD?!?!?!?

[MatthewLy]

Just after a month of building this new computer I decided to do my first liquid cooling. While doing my water cooling the only thing that I took out of my GPU and that was to install the water block. Using the PSU jumper that came with the pump, I then tested for any leaks and it was fine. After testing for leaks I took off the GPU jumper and plugged my GPU into my motherboard to start my computer. ( started computer with all 3 of my monitor plugged in ) My computer barely turn on long enough to reach my lockscreen before it blacks out. I tried only plugging in 1 monitor after I've restarted my computer. ( restarted computer by holding down power button ) After testing with one monitor I can log into my computer and then every works as normal. ( kind of ) After logging to my computer with only 1 monitor connected I then added 1 more monitor and it works fine. Using my computer as normal, browsing the web and watching videos are okay but as soon as I load up a game my computer then dies again. ( Black screen ) Repeating the same method, I log back into my computer after some amount of restarting. I tried running the Asus Furmark Rog Edition bench marks and it only runs about 5 seconds before it starts to stutter then my computer turns black again. My music will still play in the background while my screen is blacked out but I can't skip or do anything else. At this point I'm almost sure something is wrong with my GPU ( Asus 2080 ti ROG Strix ) because I tried an old GPU ( PNY Geforce GTX 1060 OC ) I had lying around and it ran just fine. Not really sure if its my PSU or GPU at this point.

this is where it reaches in Asus bench mark before it goes black.

If your gpu has no sigh of harm etc. Just rma it. It will take couple week at least, but since you have one bare gpu, it could be ok.

 

You should try to ddu and install new drivers.

And your gpu is going pretty hot if you can only run the test at 80c, check that the fans are working.

the gpu is currently running on a water block. no fans on gpu. 1 fan on cpu ( cpu also on a water block ) 6 total fans inside. 2 radiators. ( front, top ) installed corsair strix water block with the pre applied paste.

This is your issue you explained above. Look at GPU temps, these are higher than most air coolers. Seems like you have no cooling either on VRM's or the water block is not well in contact with the die. Just overheats and shuts off. Don't run it, re-assemble it, on idle check GPU VRM temps. Is the Corsair XG7 water block even compatible with the strix version?? Edit. It is compatible, then just probably not put together properly and there is no contact.

He has waterblock on it, most likely with zero to none contact to the die.. Prob goes over 80's, overheats and thats why it crashes.

yes, corsair has their own Strix water block and I'll try to reassemble it once I have time to get more liquid. thanks

All fix. I just added a little more thermal paste. The pre applied paste from the Corsair water block wasnt enough to have full contact. ( at least on mine ) there was barely a spot of contact when I took it apart.
