3.2 Memory Modules Flashcards
What is the primary role of memory modules?
To store temporary data for the processor to access quickly, improving system performance.
What are the two main types of memory modules by form factor?
DIMM for desktops and SODIMM for laptops and compact systems.
Why is it important to match memory type, size, and speed to the motherboard?
To ensure compatibility and avoid performance issues.
What happens when you mix memory modules of different speeds?
The system defaults to the slower module’s speed.
What does DDR stand for, and why is it significant?
DDR stands for Double Data Rate, and it improves speed, throughput, and efficiency with each generation.
What is the naming convention for DDR memory throughput?
Example: PC4-32000 refers to DDR4 with 32,000 MB/s or 32 GB/s throughput.
Why are memory modules keyed?
To prevent incorrect installation; for example, DDR3 cannot fit into DDR4 slots.
How do you install a DIMM in a desktop system?
Insert the module vertically at 90° and secure it with retaining clips.
How do you install a SODIMM in a laptop?
Insert the module at a 45° angle, then press down until it locks into place.
What is the advantage of using matched pairs of RAM modules?
Improved performance and stability, especially in multichannel configurations.
What type of memory is used in CPU caches?
SRAM (Static RAM), which is faster but more expensive than DRAM.
What is the impact of increasing system RAM?
Improved multitasking and application performance, particularly for demanding tasks.
What are the differences between DDR3, DDR4, and DDR5?
Each generation offers higher speed, throughput, and efficiency while using less voltage.
What should you check before upgrading RAM in a system?
The motherboard’s supported capacity, speed, and type of RAM.
What are the installation steps for upgrading RAM?
Power off the system, discharge static, remove old modules if needed, install new modules, and ensure they are securely seated.
