I’m trying to figure out what has been causing system instability. I was having trouble passing burn tests. I cleaned out my GPU fans and fixed an issue with a wire touching a fan. CPU and GPU tests were crashing and the GPU would crash at 70 C. I changed the EZ tuning settings from Quiet to Normal and now I can pass burn tests. OCCT 7 hours, IntelBurnTest (very high) and Prime95. Great, my CPU is now stable. The downside of Normal is that my fans, probably CPU, keep revving up and down. GPU is not working currently, however, it would crash with Furmark at 73C instead of the usual 70C. The problem is that the RX 480 has a temperature target of 80C. The RX 480 is stable if I set frequency (%) -4. It is also stable if I set Frequency (MHz) Dynamic. I’m not sure what is causing the computer to lock up. Is the GPU overheating, is it not pulling enough voltage, or is my motherboard not providing enough power. I’m thinking about upgrading my GPU to something with a bit more power and efficiency and want to make sure the card doesn’t have any problem. It could be a PSU or MB problem but I don’t have any spare parts to test. OCCT is supposed to test PSU as well but didn’t find any problems.
