WHEA-Logger Event 17 – Question about RAM and PCI-E Errors

Understanding WHEA-Logger Event 17: Diagnosing Hardware Errors Related to RAM and PCI-E Components

In the realm of computer hardware troubleshooting, encountering system warnings such as the Windows Hardware Error Architecture (WHEA) logs can be concerning. Recently, a user reported experiencing WHEA-Logger Event 17 errors after upgrading their system. This article aims to interpret these error messages, discuss potential causes—particularly focusing on RAM and PCI-E errors—and outline effective troubleshooting steps.

What is WHEA-Logger Event 17?

WHEA-Logger Event 17 indicates that the system detected a corrected hardware error. Specifically, the error message highlighted in this case references a “PCI Express Root Port” and an “Advanced Error Reporting (PCI Express)” source. Such errors typically point to issues with PCI Express devices, which include graphics cards, network cards, and other expansion components.

Sample error details:

• Component: PCI Express Root Port
• Error Source: Advanced Error Reporting (PCI Express)
• Primary Bus:Device:Function: 0x0:0x1:0x0
• Secondary Bus:Device:Function: 0x0:0x0:0x0

Interpreting these details, the error suggests a problem with data transmission or signal integrity over the PCIe interface—commonly associated with graphics cards or motherboard PCIe slots.

Probable Causes and Troubleshooting Strategies

1. Graphics Card Installation and Compatibility

2. Post-Upgrade Symptoms: The user installed a new GPU (RTX 5070 Ti) alongside a 1000W power supply. They noted that errors tend to spike during demanding applications like gaming or rendering.

3. Potential Issue: Incompatibility or instability in the GPU installation could precipitate PCIe errors. Ensuring the GPU is seated properly and that the power connectors are secure is essential.

4. Action Steps: Re-seat the GPU, test with a different PCIe slot if available, and verify power delivery.

5. Memory (RAM) Analysis

6. Key Observation: Memtest86 identified errors on one of the RAM modules, while the other appeared stable.

7. Implication: Faulty RAM can cause a range of system errors, including those related to memory integrity violations and PCIe communication errors—since memory and PCIe controllers often share resources.
8. Actions:
   • Remove the defective RAM stick and re-test the system.
