A field technician is upgrading the system memory on a high-performance desktop workstation that supports dual-channel DDR4 memory architecture. The motherboard features four memory slots labeled Slot 1, Slot 2, Slot 3, and Slot 4, organized into two separate memory channels (Channel A: Slots 1 & 2; Channel B: Slots 3 & 4). Which TWO of the following configurations or requirements must be met to ensure the system operates in dual-channel mode? (Select TWO.)
- Install matched memory modules across both Channel A and Channel B (such as Slot 1 and Slot 3).Answer
- Ensure the installed memory modules have identical capacities, clock speeds, and timing specifications.Answer
- CPopulate adjacent slots within the same single channel (such as Slot 1 and Slot 2) to activate dual-channel bus speeds.
- DUtilize 260-pin SO-DIMM modules to fit into the standard desktop motherboard memory expansion slots.
Answer
To enable dual-channel memory architecture, the technician must populate matching slots across both memory channels (e.g., Slot 1 in Channel A and Slot 3 in Channel B) and use memory modules with identical capacity, speed, and timing specifications.
Dual-channel memory operation requires installing matching memory modules across different memory channels (e.g., one in Channel A and one in Channel B) with identical capacity, clock speed, and timing characteristics.
