Difficulty: HardRAM Types and Characteristics

An IT specialist is configuring memory upgrades for a batch of high-performance mobile workstations used for field site telemetry analysis. The system hardware specifications require DDR4 memory operating in a dual-channel configuration. Which TWO of the following requirements must be satisfied when selecting and installing these memory modules to guarantee physical compatibility and dual-channel performance?

  1. Select 260-pin SO-DIMM modules specifically designed for mobile form factors.Answer
  2. Install identical capacity modules into designated matching slots across separate memory channels.Answer
  3. C
    Select 288-pin unbuffered DIMM modules to maximize bus bandwidth.
  4. D
    Populate matching modules into adjacent motherboard slots labeled Slot 1 and Slot 2.

Answer

To ensure proper installation and dual-channel operation on mobile workstations, the technician must select 260-pin SO-DIMM form-factor modules and populate identical modules into matching slots across separate memory channels.
Selecting 260-pin SO-DIMM modules ensures proper physical fit in mobile workstation motherboard slots, while populating identical memory modules in matching slots across distinct memory channels activates dual-channel throughput.

Step-by-Step Solution

1
Determine the physical form factor requirement for mobile workstations.
Laptops and mobile workstations use Small Outline Dual In-line Memory Modules (SO-DIMMs), which feature 260 pins for DDR4 memory, unlike standard 288-pin desktop DIMMs.
Full-size desktop DIMMs will not physically fit into mobile motherboard slots.
2
Determine the installation arrangement required for dual-channel memory activation.
Modules must be installed in alternating/color-coded slots corresponding to separate channels (e.g., Slot 1 and Slot 3 or Channel A Slot 1 and Channel B Slot 1).
Populating adjacent slots (Slot 1 and Slot 2) typically places both modules on the same memory channel, resulting in single-channel operation.
