Process usage fluctuates unpredictably and affects frame rate.
Process usage fluctuates unpredictably and affects frame rate.
Configuration - Ryzen 5 5600X connected with a Radeon 7800X on an MSI B550M-A Pro board, 32GB of Kingston Fury CL16 RAM in dual channel and an MSI Magma A750GL PSU. I’ve been running it for a month now. GPU usage is decreasing and frame rates are dropping significantly, especially in games like Hogwarts Legacy (GPU utilization falls to 20%), but it still drops to 60-70% in titles such as Forza Horizon 5 and GTA V. I’m unsure why, but when playing CS2 for over 15 minutes my PC freezes and I have to restart it to get it working again. Cinebench and FurMark function perfectly without issues or throttling. I’ve tried disabling the rear bar and it helped temporarily until the problems returned. I’ve also overclocked and undervolted the GPU, but nothing changed. This issue has been present since the start of my build. Temperatures are normal, around 65°C for both CPU and GPU. My main concern is the motherboard—it only has a single 4-pin header for CPU power, not the standard 8-pin. Also, there’s no heatsink for the VRMs.
If the issue was the motherboard, Cinebench didn’t throttle much. Your 5600X seems to perform similarly to others, indicating minimal throttling. Regarding power delivery, it provides sufficient voltage for the 5600X, especially since it’s a mid-range CPU with lower power consumption. The VRM design can keep things cool without needing a heatsink when there’s not excessive heat buildup; natural airflow helps dissipate warmth. If stability concerns arise, running OCCT tests could help identify problems related to PSU, GPU VRAM, or power delivery. This test evaluates various aspects like VRAM and other factors that might not be fully stressed by Furmark.
I gathered sensor information using hwinfo64. When my GPU usage decreases, the CPU core clock falls from 4.4 to 3.8 GHz and the TDC also drops simultaneously. The GPU frequency varies widely between 3800 and 4400 MHz, yet this doesn't match the observed CPU slowdown. This is the conclusion I drew from hwinfo.
Temps are all fine. gpu max at 70 cpu max at 80-85 when tested by occt under 100% load. Also another weird update- GTA5 crashes 10 mins into the game. My screen goes black and gpu fans go into full blast. I have to turn off my pc manually. And when I power it on my display drivers are somehow not compatible with the amd adrenalin software and I am stuck at 1080p resolution and cannot change it. So I use DDU to uninstall the drivers and reinstall them again. After that the display is fine but only till I run GTA5 again and it does the same damn thing.
Temperature seems high, but the software behavior is unusual.
Hotspot tends to run hotter, around 85 degrees. The driver problem was different this time. I was playing CS2 and the GPU stayed stable until about 20 minutes, then it crashed with a black screen, fans sped up, and I had to restart my PC manually. This year’s GPU seems new, maybe it’s faulty, but that’s unusual.
