PCIe state and workload
Interpret current link speed, width and supported maxima in workload context. Idle downshifts may be power saving; an idle reading does not establish insufficient bandwidth under load.
Troubleshooting & recovery
Hardware & runtime checks
Read PCIe links, memory state and VC++ runtime status to identify configuration clues worth investigating. Checks do not automatically modify BIOS settings or equate unavailable readings with hardware failure.
Mechanisms and technical considerations
Memory parameter conventions
Memory clock and effective transfer rate use different conventions; differing numbers do not automatically mean performance is halved. XMP/EXPO hints support manual review, with configuration and stability checked against device support.
Runtimes and reading reliability
Runtime checks identify dependency state; sensor checks expose currently readable information. Missing values may reflect support or permissions and require review. Software checks are not a replacement for hardware diagnosis.
Validation method
- Wait for detection and distinguish current readings, supported maxima and unavailable values.
- Recheck unusual values and cross-check with vendor tools under a known workload.
- Confirm the issue type before choosing manual remediation; do not change BIOS settings from one hint alone.
