A technician is troubleshooting a blade server with correctable memory errors on only one DIMM. Which of the following troubleshooting steps should the technician take FIRST?

Correctable memory errors logged against a single identified DIMM indicate that module is the likely faulty component. Replacing the suspected DIMM with a known-good module directly addresses the identified hardware fault and confirms whether the errors were caused by that specific module. This follows hardware troubleshooting methodology where the most directly implicated component is replaced first before performing more disruptive or extensive actions.

Swapping the DIMM to another slot helps isolate whether the fault is in the slot or the module, but since a specific DIMM is already identified as the error source, direct replacement is more efficient.

Replacing all DIMMs in the bank is excessive and costly when only one specific DIMM has been identified as faulty.

Applying OS and application software patches addresses software-level issues and has no bearing on hardware memory errors occurring at the DIMM level.
