Do I have a unstable overclock?

[TastyGuava]

So I've been trying to overclock my RTX 2060 for a while now (and I don't know if RAM or CPU could make a GPU OC more unstable since I had a very poorly done RAM and CPU overclock that I redid recently and my PC has been running a lot smoother all together and with higher framerates) but I got it to +120 Core and +900 Memory and after extended testing I had no crashes or visual artifacting. But I went to play some Overwatch today and all of the sudden it looked like someone pissed on my screen and I was wondering whether memory or core could cause it or is it just a combination? I had no stuttering or crashes just color shifting slowly and it's only been this one game. I do have it on max settings and I don't know if that could cause an issue on it?

 

Also I was playing some Modern Warfare (2019) Battle Royale and when I had the DirectX Raytracing it caused a bunch of visual issues but with it off my game runs perfect and better than ever.

 

I also played a bunch of R6 and had 0 issues which is what I had my main issues on when I overclocked before.

It's probably your GPU OC. I could MAX out the memory OC on my 2080S and have no artifact/crashes on any benchmarks or games, but in Escape from Tarkov I would get random flashes of colour on my screen. Brought down my mem OC and it was fine.

It’s definitely your VRAM, +900 is a lot.
