CPU Installation 3.4

Why is ESD protection important when installing a CPU?

Static discharge can permanently damage sensitive CPU components.

What tools help prevent ESD damage?

Use a static mat and wear a wrist strap clipped to it.

Why must you verify BIOS/UEFI support before installing a CPU?

A CPU may physically fit but won’t function if not supported by the BIOS/UEFI.

What happens if you power on a CPU without a cooler?

It can overheat and become permanently damaged within seconds.

What is thermal paste used for?

It increases heat transfer efficiency between the CPU and cooler.

What are alternate names for thermal paste?

Thermal grease, heat sink compound.

What is the first physical step in CPU installation?

Lift the socket lever to prepare for CPU insertion.

Why is modern CPU socket orientation safer than older ones?

Sockets are keyed so the CPU can only be inserted one way.

How can you find Pin 1 on a CPU?

Look for a small golden triangle on one corner of the CPU.

What should you do if the CPU doesn't drop in easily?

Check the Pin 1 alignment — it's likely misaligned.

What does the socket lever do after CPU insertion?

It locks the CPU securely in place.

What does it mean if the CPU can still be removed after lowering the lever?

The installation was incorrect or the socket is damaged.

Why must a CPU cooler be installed before powering the system?

To prevent instant CPU overheating and damage.

What type of mounting mechanism do Intel coolers use?

Four-point push connectors.

What type of mounting mechanism do AMD coolers use?

Locking latch.

What do aftermarket CPU coolers often include?

Mounting hardware for both Intel and AMD sockets.

Why is just installing a cooler not enough for proper cooling?

You also need airflow provided by a powered fan.

Where do you connect the CPU cooler fan?

To the CPU fan header on the motherboard, often labeled "CPU Fan 1" or similar.

What must also be installed before powering on the system?

RAM (memory).

What should you check in the BIOS/UEFI after CPU installation?

That the CPU is detected and correct settings are applied.

What used to be required for CPU setup in older systems?

Manual configuration of the CPU multiplier in BIOS.

What is the benefit of upgrading a CPU?

It can significantly boost overall system performance.

What should you do before purchasing a CPU upgrade?

Research motherboard compatibility with the new processor.

Why is it important to match the socket type and processor speed?

Mismatched components can prevent the CPU from functioning or limit performance.

What should you do before removing the CPU from packaging?

Ensure you are properly grounded to avoid ESD damage.

How should you handle the CPU during installation?

By the edges — avoid touching the pins or contacts.

Why must you not insert the CPU at an angle?

It can bend pins or damage the socket.

What do you do if a CPU doesn’t go in easily?

Stop and realign it — never force it.

What does thermal paste help correct between CPU and cooler?

It fills surface imperfections for better heat transfer.

What should you check for in a multi-processor system?

Install a terminating resistor in unused CPU slots.

Why must multi-processor CPUs match in speed?

Mismatched speeds can cause system errors or instability.

When might a thermal pad be used instead of paste?

Some heat sinks include thermal pads as a simpler alternative.

What happens if the BIOS doesn’t support the CPU’s full speed?

The CPU may run at a lower-than-rated speed.

How can you add support for a newer CPU in an older motherboard?

Update the BIOS/UEFI firmware.

Why update the BIOS after installing a new CPU?

To ensure correct recognition and performance of the CPU.

What does EDB help prevent?

It helps block buffer overflow attacks and stops malware from executing.
