REVIEWING THE BASICS

1)Name two ways that a SIMM and a DIMM are alike. Name two ways they are different.

 

 

  1. How many pins are on a SDRAM DIMM? On a DDR DIMM? On a SIMM? On a RIMM?

 

  1. Which is likely to be more expensive, a 512-MB DIMM or a 512-MB RIMM? Why?

 

  1. How many notches are on a DDR SDRAM module?

 

 

  1. What prevents a DDR DIMM from being installed in a DDR2 DIMM slot on a motherboard?

 

  1. What component must be installed in every empty memory slot on a motherboard using Rambus technology?

 

  1. What types of memory can be used on a 100-MHz motherboard?

 

 

  1. Looking at an SDRAM DIMM, how can you know for certain the voltage needed by the module?

 

  1. How many 30-pin SIMMs are installed in one bank?

 

 

  1. How many 72-pin SIMMs are installed in one bank?

 

 

  1. What are two speeds of RIMMs?

 

 

  1. List at least four things you can do if you receive memory errors during a memory upgrade.

 

  1. What might be a symptom in Windows of unreliable memory on a motherboard?

 

 

  1. List at least four things you can do if you receive memory errors during normal operation when you have not recently upgraded memory.

 

 

    1. If your motherboard calls for 60-ns memory, can you substitute 70-ns memory? Why or why not?
    2. When buying memory, what can you look for that might indicate that the memory is remanufactured?

 

    1. Which memory module standard (RIMM or DIMM) is an open standard? Which standard is a copyrighted standard?

 

    1. What is the data path size of a SIMM? A current DIMM?

 

 

    1. What are the two current data path sizes of RIMMs?

 

 

    1. What improvements did DDR make over regular SDRAM?

 

 

    1. When a DIMM has chips on both sides of the module, do the pins on one side of the module work independently or dependent to pins on the other side of the module?

 

    1. Which is faster, CL3 memory or CL5 memory?

 

 

    1. You are looking to purchase two DIMMs running at 400 MHz. You find DIMMs advertised at PC4000 and PC3200. Which do you purchase?

 

    1. You need to find out how much RAM is installed in a system. What command do you enter in the Run dialog box to launch the System Information utility?

 

    1. Although ECC memory costs more than non-ECC memory, why would you choose to use it?

 

THINKING CRITICALLY

 

  1. If your motherboard supports DIMM memory, will RIMM memory still work on the board?

 

  1. If your motherboard supports ECC SDRAM memory, can you substitute SDRAM memory that does not support ECC? If your motherboard supports buffered SDRAM memory, can you substitute unbuffered SDRAM modules?

 

  1. You have just upgraded memory on a computer from 64 MB to 128 MB by adding one DIMM. When you first turn on the PC, the memory count shows only 64 MB. Which of the following is most likely the source of the problem? What can you do to fix it?
  1. Windows is giving an error because it likely became corrupted while the PC was disassembled.
  2. The new DIMM you installed is faulty.

 

  1. The new DIMM is not properly seated.

 

  1. The DIMM is installed in the wrong slot.

 

  1. Your motherboard supports dual channeling and you currently have two slots used in Channel A on the board. You want to install an additional 512MB of RAM. Will your system run faster if you install two 256 MB DIMMs or one 512 MB DIMM? Explain your answer.
