Question 185 of 144
SK0-005 server-hardware-installation-management Practice Question
A server has four memory slots on two channels (A and B). Currently, DIMM_A1 and DIMM_A2 are populated with 8 GB DDR4-2666 modules each. To maximize performance and capacity, which memory configuration should be added?
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
✓
Add two 8 GB DDR4-2666 modules to DIMM_B1 and DIMM_B2
To achieve dual-channel performance, populate both slots on channel B with identical modules. Adding two 8 GB modules to channel B will enable dual-channel operation and increase capacity to 32 GB symmetrically.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Add two 8 GB DDR4-2400 modules to channel B
Why it's wrong here
Incorrect. Mismatched speeds (2400 vs 2666) will cause the system to run at the lower speed, reducing performance.
- ✗
Add one 8 GB DDR4-2666 module to DIMM_B1
Why it's wrong here
Incorrect. While it adds capacity, the single module on channel B will not enable dual-channel operation; performance will be single-channel.
- ✗
Add one 16 GB DDR4-2666 module to DIMM_B1
Why it's wrong here
Incorrect. This would create an imbalance in capacity between channels, potentially reducing performance to single-channel mode.
- ✓
Add two 8 GB DDR4-2666 modules to DIMM_B1 and DIMM_B2
Why this is correct
Correct. Matching capacity and speed on both channels enables dual-channel mode, maximizing bandwidth and increasing capacity to 32 GB.
