• PC3-6400

• PC3-8500

• PC3-10600

• 
  PC3-12800

  
  

What package does DDR3 SDRAM use for desktop PCs?

• 30-pin

  
  

• 168-pin

  
  

• 172-pin

  
  

• 240-pin

  
  

Why is SDRAM faster than regular DRAM?

• It makes two processes per clock cycle.

  
  

• It runs synchronously with the system clock.

  
  

• It uses dual-channel architecture.

  
  

• It has fewer pins, resulting in fewer corrupt bits.

  
  

What is the minimum requirement for RAM for Windows 10?

• 512 MB

  
  

• 1 GB

  
  

• 2 GB

  
  

• 4 GB

  
  

What does a non-maskable interrupt cause the CPU to produce?

• The Blue Screen of Death

  
  

• A parity error

  
  

• Excessive heat

  
  

• An incorrect memory count

  
  

What happens if you mix RAM sticks of different speeds?

• Your computer will work fine as long as it uses dual-channel architecture.

  
  

• Your computer may slow down.

  
  

• Your computer will work fine if all the memory modules are slower than the speed of the motherboard.

  
  

• Your computer may lock up every few seconds or provide corrupted data.

  
  

What does the CPU use to access the system’s RAM?

• The system bus

  
  

• ReadyBoost

• The address bus

  
  

• The expansion bus

  
  

Which of the following is a valid package size for DDR4 DIMMs?

• 204-pin

  
  

• 240-pin

  
  

• 260-pin

  
  

• 288-pin

  
  

If you upgrade your memory but notice that Windows Settings does not reflect the additional memory, what should you do?

• Remove the RAM and try to reinstall it.

  
  

• Restart the computer.

  
  

• Return the memory because it’s probably bad.

  
  

• Go to Setup and configure the memory to reflect the new amount.

  
  

Silas has an AMD-based motherboard with two sticks of DDR3 RAM installed in two of the three RAM slots, for a total of 8 GB of system memory. When he runs CPU-Z to test the system, he notices that the software claims he’s running single-channel memory. What could be the problem? (Select the best answer.)

• His motherboard only supports single-channel memory.

  
  

• His motherboard only supports dual-channel memory with DDR2 RAM, not DDR3.

  
  

• He needs to install a third RAM stick to enable dual-channel memory.

  
  

• He needs to move one of the installed sticks to a different slot to activate dual-channel memory.
