Hello
I am experiencing intermittent GPU-related system instability on my MSI MAG B850 TOMAHAWK MAX WIFI motherboard.
My system configuration:
During gaming (mainly World of Warcraft, but also observed in other situations), the system occasionally experiences a GPU timeout:
CPU and memory stability tests pass.
GPU temperature is normal.
VRAM tests pass.
Troubleshooting already performed:
After updating BIOS to 7E62v2A64, I tested the system with completely default BIOS settings:
My questions:
Thank you.
I am experiencing intermittent GPU-related system instability on my MSI MAG B850 TOMAHAWK MAX WIFI motherboard.
My system configuration:
- Motherboard: MSI MAG B850 TOMAHAWK MAX WIFI (MS-7E62)
- CPU: AMD Ryzen 7 9800X3D
- GPU: Palit GeForce RTX 3070 Ti GamingPro
- PSU: DeepCool PQ850M 850W
- RAM: DDR5 32GB, currently running at JEDEC 4800 MT/s (EXPO disabled)
- BIOS versions tested:
- Previous BIOS: E7E62AMSI.2A62
- Current BIOS: 7E62v2A64
During gaming (mainly World of Warcraft, but also observed in other situations), the system occasionally experiences a GPU timeout:
- The image freezes for several seconds.
- Sometimes the screen briefly disappears and recovers.
- Sometimes the GPU driver recovers automatically and the system continues working.
- In more severe cases, the system requires a restart.
- Source: nvlddmkm
- Event ID: 153
- Message:
- \Device\Video3
- Error occurred on GPUID: 100
CPU and memory stability tests pass.
GPU temperature is normal.
VRAM tests pass.
Troubleshooting already performed:
- Clean NVIDIA driver installation using DDU.
- Different NVIDIA driver versions tested.
- EXPO disabled.
- RAM tested at default JEDEC 4800 MT/s.
- GPU tested in another PCIe slot:
- Secondary PCIe slot
- PCIe Gen3 mode
- Power Limit reduced to 80%
- Main PCIe slot tested with:
- PCIe Gen4 forced manually instead of Auto.
- ASPM disabled.
- NVIDIA Control Panel:
- Power management mode set to “Prefer maximum performance”.
- CPU NB/SoC Voltage was tested manually at 1.25V.
- GPU power connection verified:
- Two separate PCIe power cables from PSU to GPU.
After updating BIOS to 7E62v2A64, I tested the system with completely default BIOS settings:
- PCIe settings Auto.
- EXPO disabled.
- RAM 4800 MT/s.
My questions:
- Are there any known PCIe compatibility issues between MSI B850 motherboards and older PCIe 4.0 NVIDIA GPUs such as RTX 30 series?
- Does BIOS 7E62v2A64 contain any PCIe/AGESA fixes related to GPU link stability, PCIe power states, or nvlddmkm recovery errors?
- Are there recommended BIOS settings for this motherboard when using RTX 30 series GPUs?
- Could this behavior be related to PCIe link training, ASPM, CPU I/O/SoC behavior, or AGESA firmware?
- Are there any diagnostic logs or tests you recommend to determine whether the motherboard PCIe subsystem or the GPU is responsible?
Thank you.
