Difficulty: MediumRAM Types and Characteristics

A technician is assembling a desktop workstation and has two matching 16 GB DDR4 memory modules. The motherboard contains four RAM slots labeled A1, A2, B1, and B2, representing memory Channel A and Channel B. To ensure the system operates in dual-channel mode as recommended by the motherboard documentation, which pair of slots should the technician populate?

  1. Slots A2 and B2Answer
  2. B
    Slots A1 and A2
  3. C
    Slots B1 and B2
  4. D
    Two SO-DIMM modules in slots A1 and B1

Answer

Slots A2 and B2
Dual-channel memory operation requires installing matching RAM modules into separate memory channels. Populating one slot on Channel A (A2) and one slot on Channel B (B2) enables the system's memory controller to utilize dual-channel performance.

Step-by-Step Solution

1
Identify memory channel architecture rules.
Dual-channel operation requires installing matching memory modules across two distinct channels (Channel A and Channel B).
Distributing modules across channels allows the memory controller to communicate with both modules simultaneously over a 128-bit wide bus path.
2
Map motherboard slot designations to channels.
Slots designated with prefix A (A1, A2) belong to Channel A, while slots with prefix B (B1, B2) belong to Channel B.
Choosing one slot from Channel A (A2) and one slot from Channel B (B2) satisfies the dual-channel population requirement.
3
Verify memory module form factor compatibility.
Standard desktop motherboards require full-size DIMM modules.
Laptop SO-DIMM modules feature a smaller footprint and key notch positioning that will not fit full-size desktop motherboard slots.
