Graphics card performance lowered suddenly?

[Razero]

I have a 4 month old rtx 2070 which was running fine before except for once or twice it caused my setup to crash after artifacting during gaming which i used to think was maybe because i was playing a game famous for being buggy and gave no heed until recently it happened again,with another game, but on restarting i started getting artifacts all over my desktop background and i did another forced reset, the artifacting was gone but afterburner, rgb fusion, and dxdiag couldn't detect my gpu, so i tried reinstalling the gpu drivers and it was now detectable,but now all of the games are giving lesser performance than before, like 80-110 fps on shadow of tomb raider than than 100-135,and it heavily impacted minecraft(with shaders) which used to run above 90 fps is now barely running 38-45 fps, i tried reinstalling graphic drivers multiple times but it isnt helping, it is also running 1-2° cooler than before(not sure maybe due to weather), i m thinking about RMAing it but i want to know what happened exactly that my performance is diminished, i enabled the same previous settings in my settings but that changes nothing as well?

Early batches of Nvidia GDDR6 cards are known for VRAM failing early, so just RMA. I'm surprised that you got it working even tho at the cost of a slow down tbh

VRAM failure? is that what happened? i had a feeling that something was up with my card because it used to reach 78°c as soon as i put it on full load even without overclocking, the retailer just kept saying that it is common.

temperature depends on the model of 2070. GDDR6 artifacting affects everything from 2080Ti to 1660Ti, excluding the Super cards that came later. It happened to all custom and reference models, including those sold directly by Nvidia. The exact cause is not really clear, I think it has to do with the memory controller in the GPU since it's unlikely for both Micron and Samsung to screw up all their early batches of GDDR6 at once like this.

Well just for the information, it is this one:https://www.techpowerup.com/gpu-specs/gigabyte-rtx-2070-gaming-oc.b6184

I hope this helps.
