Rust is poorly optimized and immediately pegs my GPU at full and constant load and pulls on my CPU pretty good too. Downclock your CPU, might help. As a test, set your 8320 at 4.2GHz and run the benchmark built into CPU-Z and let me know what you get. I had some pretty noticeable shifts in CPU performance / stability by changing some power settings in my BIOS. I'm curious how yours does. Running CPU benchmarks by themselves are not always the greatest indicator of stability, particularly with the power hungry components we run. GTA V is my usual long term stability test because it pulls so much power from both my CPU and GPU and makes' em work for it. Our builds are practically identical so I can probably give you some performance insight and see what might be going on. Is your 390 overclocked at all? Have adjusted power limits at all? (See my sticky in the GPU subforum)
Has anyone seen a website where I can order such a thing for a reasonable price ???
How can I improve the sale-ability of my goods ???
I did not find the right solution from the internet.
