Zorluk: Çok zorRAM Types and Characteristics

An IT support technician is upgrading the memory on a high-performance mobile workstation laptop that currently suffers from memory bottlenecks during CAD rendering. The laptop motherboard supports dual-channel DDR4 memory up to 3200 MHz. The technician needs to procure and install a new 32 GB memory configuration. Which TWO of the following specifications or installation steps must the technician ensure to achieve physical compatibility and enable dual-channel mode?

  1. Select 260-pin SO-DIMM modules specifically designed for laptop motherboards.Cevap
  2. Install matching memory modules into designated memory slots across both Channel A and Channel B.Cevap
  3. C
    Select 288-pin unbuffered DIMM modules to ensure full bus-width bandwidth.
  4. D
    Populate both memory modules into adjacent slots designated exclusively for Channel A.

Cevap

The technician must select 260-pin SO-DIMM modules for laptop form-factor compatibility and populate matching modules across both Channel A and Channel B slots to activate dual-channel architecture.
Selecting 260-pin SO-DIMM modules ensures correct physical pin keying and dimensions for a laptop memory upgrade. Installing matching modules across separate memory channels allows the memory controller to access RAM concurrently over a 128-bit wide bus, enabling dual-channel operation.

Adım Adım Çözüm

1
Determine the physical form factor required by the system chassis.
Laptops require SO-DIMM form factor modules (260 pins for DDR4), whereas desktop motherboards take standard 288-pin DIMM modules.
Full-sized desktop DIMMs will not fit inside the smaller spatial footprint of a laptop motherboard.
2
Determine the motherboard slot configuration for multi-channel memory operation.
Dual-channel throughput requires placing memory modules into alternating slots belonging to separate channels (Channel A and Channel B).
Installing both modules into adjacent slots on the same channel restricts the system to single-channel 64-bit communication instead of dual-channel 128-bit communication.
