Which OS-side indicator suggests memory DIMM issues?

• A. Kernel logs show ECC corrections/uncorrectables; rising counts suggest DIMM issues.
• B. High CPU temperature spikes.
• C. Disk I/O latency spikes.
• D. Network interface errors.

Answer: (A)

Memory issues on DIMMs show up in the operating system as ECC error reports from the memory subsystem. ECC can correct single-bit errors, and you’ll see messages about corrected errors in kernel logs. If the counts of corrected errors start to rise, that’s a warning sign that a DIMM or the memory controller may be degrading. In more severe cases, uncorrectable errors will appear, indicating a failing module that could lead to data corruption or crashes if not addressed. This OS-side evidence is the clearest signal that there’s something wrong with memory hardware.

Other symptoms point to different subsystems: high CPU temperatures relate to cooling or workload, disk I/O latency spikes point to storage performance issues, and network interface errors indicate problems with networking hardware or drivers. So the key indicator for memory DIMM problems is the appearance and increasing frequency of ECC corrections (and any uncorrectable errors) in the OSLogs.
