Q

external clock speed

A

Frequency of the front side bus which connects the Northbridge to the CPU.

Newer motherboards do not use anymore.

18
Q

You are troubleshooting a CPU and have already cut power, disconnected the power cable, opened the case, and put on your antistatic strap.

What should you do next?

A

Check the connections of the motherboard / CPU.

19
Q

When deciding on a CPU for use with a specific motherboard, what does it need to be compatible with?

What is the amount of power required to cool the computer?

A

Thermal Design Power (TDP) aka Thermal Design Point.

32
Q

Which kind of socket incorporates “lands” to ensure connectivity to the CPU?

A

Land Grid Array (LGA)

33

34
Q

motherboard bus speed

A

Base clock speed of the motherboard.

35
Q

HyperThreading

A

Intel’s instruction set that allows a single CPU to accept and calculate two independent sets of instructions simultaneously which is present in Pentium 4s and the new i3, i5, i7’s.

36
Q

You just completed a CPU installation. However, when you turn on the computer, the POST sounds a series of beeps, and the system won’t boot.

What is most likely the cause?

A

The CPU is not properly seated (also there could be a RAM issue).

37
Q

LGA

A

Land Grid Array Socket use “lands” that protrude from the socket and touch contact points on the CPU.

Better power distribution and less chance of damaging CPU.

Commonly used on Intel Motherboards.

38
Q

Where is thermal paste / compound applied to : CPU Cap or Heat Sink?

A

Apply thermal paste to CPU Cap and not heat sink.

39
Q

What is the difference between clock speed and bus speed?

A

Clock speed is referred to the CPUs internal clock speed and the bus speed refers to the motherboards clock rate or front side bus speed.

40
Q

What is another name for the speed of the CPU?

A

Internal Clock Speed

41
Q

Four A+ CPU Troubleshooting Steps

A
  1. Check the big four (CPU, RAM, Video Card, Motherboard) for compatibility.
  2. Fan is connected and functional.
  3. Heat Sink is connected properly.
  4. CPU installed properly with correct orientation and flush in the socket.
42
Q

Thermal Design Power

A

The maximum power that the computer’s cooling system needs to dissipate heat generated by the CPU.
