Configured Memory Speed: 1866 MT/sRefer to the exhibit. A server administrator runs a dmidecode command to check memory configuration and obtains the output shown. The system supports DDR4-2666, but all DIMMs are running at 1866 MT/s. Which action will allow the memory to run at the maximum supported speed?
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 A1 with a DDR4-2666 registered module.
Correct: The slower 2133 MT/s DIMM in slot A1 limits all modules to its speed. Replacing it with a 2666 MT/s module allows the system to run at the highest common denominator. Option A is wrong because reordering slots won't change the speed limitation. Option C is wrong because XMP is for overclocking desktop memory, not typical on registered server DIMMs. Option D is wrong because clearing CMOS only resets BIOS settings, not memory speed mismatch.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable XMP profile in the BIOS to force all DIMMs to 2666 MT/s.
Why it's wrong here
XMP (Extreme Memory Profile) is an overclocking feature typically unavailable or unsuitable for stable server operations with registered memory.
- ✓
Replace the DIMM in slot A1 with a DDR4-2666 registered module.
Why this is correct
All memory runs at the speed of the slowest module. Replacing the 2133 MT/s DIMM removes the bottleneck.
- ✗
Clear the CMOS to reset the memory training data.
Why it's wrong here
Clearing CMOS might trigger retraining but will not override the hardware limitation imposed by the 2133 MT/s DIMM.
- ✗
Move the DIMM from A1 to A2 and the DIMM from A2 to A1.
Why it's wrong here
Swapping slots does not eliminate the speed mismatch; the slowest DIMM still dictates the memory bus speed.
