Question 84 of 144
SK0-005 server-hardware-installation-management Practice Question
A server has been randomly rebooting several times a day with no pattern. The administrator reviews the IPMI System Event Log and finds multiple 'Correctable ECC error' entries for DIMM slot B2. The server memory is configured with 16 DIMMs of the same type and manufacturer, all recently installed. What should the administrator do FIRST to resolve this issue?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Replace the DIMM in slot B2 with an identical spare.
Correctable ECC errors indicate a failing or marginal memory module. The first step is to replace the DIMM showing errors. Option A is wrong because reseating does not guarantee the errors will stop, and the DIMM is likely faulty. Option C is wrong because while increasing voltage might help with stability, it is not recommended as a first fix and could void warranty. Option D is wrong because disabling ECC removes error correction but does not fix the underlying hardware fault.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Disable ECC in the firmware to prevent the module from reporting errors.
Why it's wrong here
Disabling ECC would mask the error but would still leave the faulty module in place, increasing the risk of data corruption.
- ✗
Reseat the DIMM in slot B2 and run a memory diagnostic test.
Why it's wrong here
Reseating may temporarily fix a poor connection, but ECC errors usually indicate a failing DIMM that should be replaced.
- ✗
Increase the DRAM voltage slightly in the BIOS/UEFI to improve stability.
Why it's wrong here
Overvolting can damage components and is not a standard remediation for ECC errors; besides, the modules are all identical and within spec.
- ✓
Replace the DIMM in slot B2 with an identical spare.
Why this is correct
Correctable ECC errors point to a physical memory fault; proactive replacement prevents uncorrectable errors and downtime.
