At first, I tried to overclock. I found out that my GPU VRAM speed runs stable at 2630MHz, with default clock speed. Then, I attempted to maximize what the GPU can do and increased the GPU clock speed without any issues. I tested it to restart my PC on this day to check if it works without any problems and yes it work how it should. I ran memtest Vulcan, OCCT, and 3DMark without any issues (you can see the results in this picture and this link: https://www.3dmark.com/3dm/100669134). The gpu will not too hot they are always by 45-50C° (hotspot 65C°) with 100% usage. However, after a day, when I started my PC again, it didn’t run stably anymore, and I don’t know why because it seems like I have a different GPU. This is the first problem: the AMD app shows incorrect values after a crash, and I have different GPU clock speeds every time.
If anyone has any idea why it’s running unstable, please help me.
