Difficulty: HardRAM Types and Characteristics

A field technician is configuring a small-form-factor graphics workstation whose motherboard specifically requires DDR5 SODIMM modules. The technician needs to ensure proper physical compatibility and optimal system performance. Which TWO of the following statements correctly describe the technical or physical characteristics of these memory modules? (Select TWO.)

  1. SODIMM modules have a shorter physical form factor than standard DIMMs and utilize distinct notch positions that prevent installation into full-size desktop slots.Answer
  2. Each individual DDR5 memory module natively incorporates two independent 32-bit memory channels on a single physical stick.Answer
  3. C
    Standard desktop DIMM modules can be installed into SODIMM slots by trimming the protective plastic alignment tabs on the motherboard socket.
  4. D
    Installing matching memory modules into adjacent slots designated for Slot 1 and Slot 2 on a four-slot motherboard activates multi-channel performance.

Answer

The correct statements are that SODIMM modules have a shorter physical form factor with unique notch positions preventing installation into standard desktop DIMM slots, and that each individual DDR5 memory module natively features two independent 32-bit subchannels.
The correct statements accurately identify key characteristics of RAM types: SODIMMs provide a smaller footprint tailored for compact systems and laptops with physical keying preventing insertion into desktop DIMM slots, while DDR5 architecture split each physical module's bus into two independent 32-bit subchannels for enhanced concurrent data access.

Step-by-Step Solution

1
Analyze the physical form factor requirements for small-form-factor SODIMM memory.
Confirm that SODIMM modules are physically smaller and keyed differently than standard desktop DIMM modules to prevent incorrect insertion.
Form factor alignment is a physical hardware constraint.
2
Evaluate the architectural specifications of DDR5 memory technology.
Identify that DDR5 introduces internal dual subchannels (two 32-bit channels per stick) to enhance memory bandwidth efficiency.
DDR5 architectural design differs fundamental from DDR4 single 64-bit channel layout.
3
Evaluate distractor claims regarding socket modifications and channel population.
Recognize that physical socket tabs must never be cut to fit mismatched form factors, and dual-channel operation requires populating designated alternating motherboard slots rather than adjacent ones.
Prevents physical hardware damage and performance degradation due to improper slot placement.
