Difficulty: MediumRAM Types and Characteristics

A technician is performing a RAM upgrade on a compact All-in-One desktop system that uses a mobile motherboard architecture. The system currently contains one 8 GB memory module in slot A1, operating in single-channel mode. Motherboard documentation indicates that slot A1 belongs to Channel A and slot B1 belongs to Channel B, while slot A2 is the second slot on Channel A. To upgrade the system with a matching 8 GB module and enable dual-channel memory operation, which memory module form factor should the technician select, and into which slot should it be installed?

  1. 260-pin SO-DIMM module installed into slot B1Answer
  2. B
    288-pin DIMM module installed into slot B1
  3. C
    260-pin SO-DIMM module installed into slot A2
  4. D
    288-pin DIMM module installed into slot A2

Answer

260-pin SO-DIMM module installed into slot B1
Compact desktop designs and laptops that utilize mobile motherboard architecture require Small Outline DIMMs (SO-DIMMs), which use 260 pins for DDR4 memory. To activate dual-channel memory mode, memory sticks must be installed across distinct channels. Since slot A1 resides on Channel A, placing the second module in slot B1 on Channel B enables dual-channel memory throughput.

Step-by-Step Solution

1
Determine the physical form factor requirement for the mobile motherboard architecture.
Identified that Small Outline Dual In-line Memory Modules (SO-DIMMs) are required for mobile and compact board designs (260 pins for DDR4), whereas full-sized desktop DIMMs (288 pins) will not fit.
Compact and mobile systems use smaller form-factor slots.
2
Determine the correct slot population for dual-channel performance.
Slot A1 is on Channel A, so the second module must be installed in slot B1 on Channel B.
Dual-channel architecture requires memory modules to be distributed across separate memory channels rather than shared on the same channel.
