Which RAM would typically be installed into a laptop computer?
ECC
SPD RAM
SDRAM
SO-DIMMs
- SO-DIMMs -
Laptops and other small electronics use SO-DIMM
ECC RAM is usually found in server grade computers
SDRAM is an early generation of RAM technology but it is not specific to laptops
There is no such thing as SPD RAM
Which type of RAM can function even if one of its memory chips fail?
SO-DIMMs
ECC
Double sided RAM
Dual channel RAM
- ECC -
Error correction code (ECC) RAM and parity RAM can function with a failed memory chip
SO-DIMMs are small outline (form factor) memory modules
Dual-channel is technology that supports simultaneous access to multiple RAM modules
Double-sided RAM are RAM modules they are organized into 4 bits
In what order should memory slots be filled?
A. Whatever order the motherboard manual specifies
B. Closest to the CPU to farthest from the CPU
C. Alternate slots starting farthest from the CPU
D. Farthest from the CPU to closest to the CPU
A. Whatever order the motherboard manual specifies
What should a technician do to improve performance if the virtual memory file is constantly full?
A. Increase the size of virtual memory file
B. Add more RAM to the computer
C. Close some applications
D. The technician should do nothing; virtual memory works best when the file is full
B. Add more RAM to the computer
You are using the compTIA troubleshooting methodology to determine the cause of some faulty RAM. You theorize that one or more RAM modules might not be properly seated. You test the theory, and it seems like a probable assumption. What is your next step?
A. Identify the problem by removing all hardware components from the motherboard.
B. Remove the RAM and replace with new modules
C. Verify full system functionality by rebooting the PC
D. Implement the solution by reseating the RAM
D. Implement the solution by reseating the RAM
