Zorluk: OrtaRAM Types and Characteristics

A desktop workstation currently has a single 16 GB DDR4 DIMM installed in memory slot A1. A technician needs to install a second identical 16 GB DDR4 DIMM to optimize memory throughput for rendering applications. The motherboard contains four slots labeled A1, A2, B1, and B2. Which of the following slot configurations should the technician use to enable dual-channel memory architecture?

  1. Populate slots A1 and B1 so that each memory channel contains one matching module.Cevap
  2. B
    Populate adjacent slots A1 and A2 to consolidate memory on Channel A.
  3. C
    Replace the existing DIMM with a 260-pin SO-DIMM module to save physical space on the motherboard.
  4. D
    Install a high-frequency DDR5 DIMM into slot B1 alongside the existing DDR4 DIMM in slot A1.

Cevap

Populate slots A1 and B1 so that each memory channel contains one matching module.
To enable dual-channel memory performance, identical RAM modules must be installed across separate memory channels (e.g., Slot A1 for Channel A and Slot B1 for Channel B). This allows the memory controller to access two 64-bit channels simultaneously, effectively doubling memory bus bandwidth to 128 bits.

Adım Adım Çözüm

1
Identify motherboard memory channel layout
Slots A1 and A2 belong to Channel A; slots B1 and B2 belong to Channel B.
Dual-channel architecture requires distributing memory modules evenly across both independent memory channels.
2
Select correct slot pairing for dual-channel throughput
Installing the second module in slot B1 matches the existing module in slot A1 across independent channels.
Matching slot positions across Channel A and Channel B activates 128-bit dual-channel data bus operation.
