System shuts down following the CPU upgrade on all essential components
System shuts down following the CPU upgrade on all essential components
I recently changed my Ryzen 5 4650g to a 5950x. Since the system shuts down under heavy CPU use, it’s not always consistent (previously stable). When it powers off, RGB and fans remain active. Occasionally it restarts, but most times turning off the power supply works (without pressing the power button or hard reset).
My setup includes: Asrock B550m Pro 4 Ryzen 9 5950x Cooler Master 212 Evo MSI 3070 Suprim X 2x16GB@3200 & 2x8GB@3600, Crutial Ballistix Corsair RM750.
I know the 212 Evo may not be sufficient for the 5950x, and an upgrade is planned. However, this isn’t the main issue. The PC also experiences crashes when CPU isn’t overclocked—around 3800mhz under full load, with temperatures below 70°C. Notably, when I first installed the new CPU, it handled ~4500mhz under all loads, then throttled to ~4000mhz, always staying near 90°C and using ~150W. It would crash at that point too, but I could run a 10-minute Cinebench without issues.
After updates, I installed the latest BIOS, chipset drivers, and Ryzen Master. Still unsure what caused the change. Previously, at ~3800mhz under full load, it would crash but not often. I managed a 10-minute Cinebench run successfully.
I’ve been using Ryzen Master, and both AutoOC and manual overclocking seem to trigger crashes. AutoOC lowering power limits seems more stable, but at 150W it still crashes during Cinebench. Manual overclocking causes similar problems—even a steady 4100mhz leads to crashes during Cinebench.
In short, based on my attempts without success: the BIOS update, single RAM type, and power supply seem fine. The real cause might be something else—perhaps the PSU or mainboard. I’m not very experienced with power systems, but from OpenHardwareMonitor, mainboard temps never exceed 65°C even at high loads. Still, since my B550 is only 65W, a failure is unlikely. If I must replace it, I’d consider an X570.
But right now, I can’t afford to spend much on more parts; the AIO would have to wait.
I wanted to mention this: in Windows Event Viewer, there’s a critical error labeled ‘Kernel-Power’ with ID 41.
The airflow inside the case isn't ideal (Thermaltake h200). However, there should be ample air movement across the VRMs. The CPU cooler uses two fans to push air directly over it. I've placed the front top fan as an intake and added a lower fan that pulls air from beneath the case—this works better than three front fans would.
Does the processor fail after hitting 95°C in games? Cinebench shows less thermal stress, but I think your cooler isn’t powerful enough for sustained high loads—like in CP2077, you’re using around 10C more than it can handle. It’s likely not built for cooling beyond about 100W.
I also have strong fan curves configured, reaching full speed at 65°C CPU temperature.
