Time: 1 Hour Revision Date: 6/26/10 Overview This activity is designed to ensure that you understand the topics covered in your courseware. You are required to know the names, purposes and characteristics of processors / CPUs as well as the names, purposes and characteristics of cooling systems, tools, and diagnostic procedures. You should also be familiar with troubleshooting techniques to check for problems. The components that you identify here will be covered in more detail later in this course. Lab Activities Exercise 1: Identify Cache Memory and How it is Used Exercise 2: Identify the CPU and the Socket Exercise 3: Match the Socket to the CPU(s) Exercise 4: Fill in the Blanks in the CPU Information Exercise 1: Identify Cache Memory and How it is Used Overview: Cache memory is a type of memory which stores data that may be processed or data that has already been processed but may be used again by the CPU. 1. List the speed and size for each type of cache. a. L1 b. L2 c. L3 2. Which type of cache may have been found in a slot on the motherboard that looked like a RAM slot? 3. What does fast cache reduce? 4. Where is L3 cache found? Cyanna Education Services, 2009 Page 1
Exercise 2: Identify the CPU and the Socket Overview: CPUs come in various form factors, are manufactured by various companies, and utilize different pin counts and socket types. Research the CPU form factors and determine the distinguishing qualities. 1. Which corner of the AMD CPU would fit to which corner of the socket? 2. List the three main CPU form factors. a. b. c. 3. Write the name of the component beside the graphic. Cyanna Education Services, 2009 Page 2
Exercise 3: Match the Socket to the CPU(s) Overview: CPUs come in various form factors, are manufactured by various companies, and utilize different pin counts and socket types. 1. Research the following CPU form factors and then fill in the blanks of the chart. Slot 1 Slot 2 Socket 7 Socket 775 Socket A 2. Socket 775 sockets are unique because they have the pins on the and contacts on the processor? 3. Socket 775 sockets are known as 4. What is unique about a ZIF socket and which of the above use that style? Exercise 4: Fill in the Blanks in the CPU Information Overview: Fill in the missing word(s) in the CPU statements and commit them to memory. Liquid Cooling Systems Overclocking Thermal Grease Throttling Voltage Regulator Module 1. allows the motherboard to regulate the amount of volts used by the processor. 2. CPU reduces power consumption and heat production. 3. do a better job of cooling than a standard heat sink and fan and are quieter. 4. can cause overheating and CPU and motherboard damage. 5. Before installing the heat sink and fan, you should apply to the processor Lab Answers Exercise 1 5. List the speed and size for each type of cache. a. L1 Fast 32-128 KB b. L2 Medium 128 KB 4 MB Cyanna Education Services, 2009 Page 3

Slot 1 Intel Pentium I / II Slot 2 Intel Xeon Socket 7 Intel AMD K5 / K6, Cyrix 6x86, IDT WinChip, Pentium, Pentium MMX, Rise Technology mp6 Socket 775 Intel Pentium 4, Core 2 Duo, Core 2 Quad Socket A AMD Athlon, Athlon MP, Athlon XP, Duron, Geode NX, Sempron 2. Socket 775 sockets are unique because they have the pins on the socket and contacts on the processor? 3. Socket 775 sockets are known as Land Grid Array 4. What is unique about a ZIF socket and which of the above use that style? Socket 7 uses the ZIF socket style, which means Zero Insertion force. A lever holds the socket down and when released, the processor can be easily lifted out Exercise 4 1. Voltage regulator module allows the motherboard to regulate the amount of volts used by the processor. 2. CPU Throttling reduces power consumption and heat production. 3. Liquid Cooling Systems do a better job of cooling than a standard heat sink and fan and are quieter. 4. Overclocking can cause overheating and CPU and motherboard damage. 5. Before installing the heat sink and fan, you should apply thermal grease to the processor Cyanna Education Services, 2009 Page 5
