System instability detected: Errors increase with CPU usage - New AM5 version
System instability detected: Errors increase with CPU usage - New AM5 version
Hello, everyone
I just completed my first build using an AM5 motherboard. I believe I haven’t made any beginner errors: RAM was installed correctly, BIOS settings were standard, no overclocking was done, and the BIOS is up-to-date. The system posts and installs the OS work fine overall. Here are the specifications:
CPU – AMD Ryzen 9 7900X
GPU – MSI NVIDIA GeForce RTX 3060 Ti
DIMMs – 2x16GB DDR5 Kingston CL32 6000Mhz Fury Renegade Silver (from Mobo Ramlist)
Motherboard – ROG STRIX B650-A Gaming Wifi
PSU – EVGA 750W Gold
SSD – M.2 2280 WD Blue SN570 500GB
OS – Arch Linux
Boot – EFI GRUB
The problem remains unclear, so I’m posting this thread. It seems games are affected – random crashes under heavy CPU load. GPU benchmarks look good, RAM passed memtest with default settings, and crashes also occur with my browser and other apps over time. Based on how often they happen, it might be random, and increased CPU usage just speeds up the occurrences.
How can I troubleshoot this? Any suggestions?
Hello there! Are you familiar with the BIOS configurations, avoiding overclocking, and ensuring your BIOS is current?
What BIOS version do you have installed on your motherboard?
Which RAM slots are being used on your system? How is the processor being cooled?
Hi, and thanks for the help.
I am using the DIMMs in slots A2 and B2 (as recommended in the B650-A manual).
The BIOS is at the most recent version (1807, released 2023/10/11) updated through BIOS flashback.
This issue existed before me updating the BIOS so I don't think it is to blame.
For the CPU cooler I'm using the Cooler Master 212, CPU temp monitor shows it stable at 40ºC when idling.
lm-sensors
only gives me a few sensors, here is a composite with the all-time max values for everything:
amdgpu-pci-0c00
Adapter: PCI adapter
vddnb: 1.01 V
vddgfx: 1.47 V
edge: +45.0°C
PPT: 65.11 W
nvme-pci-0200
Adapter: PCI adapter
Composite: +41.9°C (low = -5.2°C, high = +79.8°C)
(crit = +84.8°C)
k10temp-pci-00c3
Adapter: PCI adapter
Tctl: +69.4°C
Tccd1: +76.0°C
Tccd1: +74.8°C
Not sure what the
k10temp-pci-00c3
ones are but the values only get this high when initially loading the game assets. Gameplay has much more normal values so I don't think overheating is the cause: Around 63ºC for
Tctl
and either 60 or 40ºC for each of the
Tccd
's.
Hope this can help
