As the title suggests my GPU is showing artifacts. I have just built my first waterloop. Prior to the build I did test the GPU at stock with the FE cooler it worked. Thankfully artifacts are only happening when I try to stress test the GPU or benchmarking in game.
I have the GTX 1080Ti GPU Block + backplate with the included thermal pads for VRMS and mofets. Idle temps avg 30c. Literally no less than a minute into a game or benchmark 3dmark or Unigine superpostion the apps will freeze and will show artifacts. Forcing a reboot.
I have included a video as a example of what I am experiencing hope you guys can help.
Many Thanks
Probably insufficient TIM coverage/a void in the TIM on the GPU itself, or poor VRM contact.
Are you sure all VRM components that were cooled by the stock cooler are making good contact with the waterblock?
How did you apply TIM to the GPU? Bare die parts leave no room for error and even a tiny gap/void/bubble will result in part of the die running much hotter than the surrounding area.
If you are doubly sure TIM application is fine then chances are that you damaged something swapping coolers.
I'm sure the tim was making contact with it. Because if it was not the temps would be alot higher. There was one thing I was not sure about was the VRM thermal pads when I was installing them. i put the white side on the chips themselves then the blue side touching the backplate is that correct? I was trying to replicate how the thermal pads were laid on from the stock version. I think in any case im gonna have to dismantle the gpu to see if its working or not
There are a handful of temp sensors at most; unless a void is directly over one, you aren't going to see abnormal temps. Even a few mm wide bubble/void can result in major issues because those transistors will be much hotter than those just a mm or two away.
These parts do not have heatspreaders and TIM application methods that rely on a heatspreader or that don't ensure 100% coverage will rarely work well on bare die parts.

Hi guys I dismantled the gpu it was worse than I thought. 4 of the memory chips and mosfets on the right side of the die were not installed. It's mad how I forgot to install those. Here's what it looks like now
Later on today I'll put it back in the loop. Also does anyone know where to buy the temperate sensor that EK mentions in the GTX 1080ti waterblock manual please as I would like to purchase it. Tried to find it on the store I couldn't find it any where. If you could link that would be fantastic thanks
