Zorluk: ZorRAM Types and Characteristics

A field technician is upgrading the memory in a high-performance laptop workstation used for complex engineering rendering. System specifications require dual-channel DDR5 memory with error checking functionality. Which TWO of the following RAM module characteristics or installation choices must the technician select to ensure full system compatibility and dual-channel operation? (Select TWO.)

  1. SO-DIMM module architecture to match the compact physical footprint of the laptop motherboardCevap
  2. DDR5 modules incorporating On-Die ECC (ODECC) for internal bit error managementCevap
  3. C
    Standard 288-pin full-sized desktop DIMM modules to maximize bus throughput
  4. D
    Populating matching memory modules into adjacent slots designated A1 and A2 on the same memory channel

Cevap

The technician must select SO-DIMM module architecture for physical compatibility with the laptop motherboard and DDR5 modules featuring On-Die ECC (ODECC) for memory error management.
Mobile laptops require the compact SO-DIMM form factor to fit the motherboard footprint. Additionally, DDR5 RAM includes On-Die ECC (ODECC) by design to manage memory bit errors internally, fulfilling the memory specification requirement.

Adım Adım Çözüm

1
Determine the physical form factor required by the system chassis
Laptops mandate SO-DIMM modules due to space restrictions on the motherboard.
Standard desktop DIMM modules are too large and have different pin layouts that cannot physically fit into laptop RAM slots.
2
Identify the required DDR5 error handling specification
DDR5 modules integrate On-Die ECC (ODECC) directly onto the memory chip.
ODECC protects against reliability issues caused by high cell density in DDR5 modules.
3
Evaluate correct dual-channel population rules
Modules must be installed into separate channels (e.g., Slot A1 and Slot B1) rather than adjacent slots on a single channel.
Placing modules into adjacent slots on the same channel forces single-channel operation.
