Step 2 Look at the CPUs pictured in Figure 3-1, making note of the differences you see In particular, look for the following:
Differing pin grid array (PGA) or Single Edge Contact (SEC) packages Orientation guide notches
Figure 3-1 Exploring different CPUs
Lab Exercise 302: CPU Sockets
Figure 3-2 Comparing different CPU fans
Step 3 Many different types of fans can be attached to CPUs in many different ways Describe the characteristics of the types of fans shown in Figure 3-2 A ____________________________________________________________________________ B ____________________________________________________________________________ C ____________________________________________________________________________ Step 4 On your disassembled PC, locate the CPU and fan assembly Make note of the type of CPU package and fan assembly Also note the type of power connector used for the fan: Molex, three-prong motherboard plug, or none Then replace the CPU into the anti-static bag and return the fan assembly to your work surface

Lab Exercise 302: CPU Sockets
Because you know your CPUs, you have identi ed Joe s purchase, but you explain to him that until you look at his motherboard, you can t say whether he ll be able to use it CPU compatibility is determined largely by the motherboard s support capabilities Some motherboards enable you to upgrade the PC by

replacing the existing CPU with a faster model of the same type In many cases, however, you must replace the entire motherboard if you want to move up to a faster microprocessor
Learning Objectives
In this lab, you ll identify various CPU sockets At the end of this lab, you ll be able to
Recognize different kinds of CPU sockets Know which CPUs require which sockets
Lab Materials and Setup
The materials you need for this lab are
A notepad and pencil to document the speci cations Optional: Access to a working computer with a word processing or spreadsheet application installed and access to the Internet, to facilitate research and documentation of the CPU socket speci cations The Mike Meyers A+ Guide to Managing and Troubleshooting PCs textbook for reference
This lab is more effective if you have access to different types of motherboards with different types of CPU sockets
Getting Down to Business
In the following steps, you ll review your knowledge of CPU socket types Step 1 Draw a line connecting each CPU to its corresponding socket type: CPU Pentium D 820 AMD Opteron 248 Athlon 64 X2 4200+ Pentium 4 Athlon XP 1500+ AMD Sempron 3500+ Socket Type Socket 939 Socket AM2 Socket A (PGA-462) Socket 478 Socket 940 Socket LGA-775
Step 2 Identify and describe the different socket types in Figure 3-3 Include the socket number/letter and the make and model of CPU that would t that socket Example: Socket A (PGA-462), AMD Athlon XP CPUs
