1. Introduction

This manual provides essential information for the proper installation, operation, and maintenance of your Intel Core i5-3470 processor. The Intel Core i5-3470 is a 3rd generation quad-core processor designed for the LGA 1155 socket, offering a base clock speed of 3.20 GHz. It incorporates Intel's Clear Video HD Technology, Enhanced Speed Step Technology, Virtualization Technology, and Extended Memory 64 Technology to deliver efficient performance for various computing tasks.

2. Safety Information

Observe the following safety guidelines to prevent damage to the processor and other components, and to ensure personal safety:

• Electrostatic Discharge (ESD) Precautions: Always handle the processor by its edges. Wear an anti-static wrist strap and work on an anti-static mat to prevent ESD damage.
• Physical Handling: Avoid touching the gold contacts or the top surface of the processor. Do not apply excessive force when installing or removing the processor.
• Power Off: Ensure your computer system is completely powered off and unplugged from the wall outlet before installing or removing any components.
• Cooling: A proper CPU cooler must be installed and correctly seated on the processor with thermal paste applied to prevent overheating.

3. Package Contents

Verify that your retail package contains the following items:

• Intel Core i5-3470 Processor
• Intel Stock CPU Cooler (if purchased as a boxed processor)
• Installation Guide/Documentation

4. Setup & Installation

Installing the Intel Core i5-3470 processor requires careful handling. Follow these steps for proper installation into an LGA 1155 motherboard.

4.1. Pre-Installation Checklist

• Compatible Motherboard: Ensure your motherboard supports the LGA 1155 socket and the Intel 3rd generation Core processors. Refer to your motherboard's documentation.
• Thermal Paste: If using an aftermarket cooler, ensure you have thermal paste. Intel stock coolers usually come with pre-applied thermal paste.
• Tools: A Phillips head screwdriver may be needed for cooler installation.

4.2. Processor Installation

1. Open the CPU Socket: Locate the CPU socket on your motherboard. Gently push down the load lever and pull it away from the socket to release the retention frame. Lift the load plate.
2. Align the Processor: Carefully remove the processor from its protective packaging. Align the two notches on the processor with the corresponding keys on the socket. The golden triangle on the processor should align with the triangle on the socket.
3. Insert the Processor: Gently place the processor straight down into the socket. Do not force it. The processor should sit flat and level in the socket.
4. Secure the Processor: Close the load plate over the processor. Push down the load lever and snap it back into place under the retention tab.

4.3. Cooler Installation

1. Apply Thermal Paste (if necessary): If your cooler does not have pre-applied thermal paste, apply a small pea-sized amount to the center of the processor's integrated heat spreader (IHS).
2. Position the Cooler: Place the CPU cooler onto the processor, ensuring the mounting mechanism aligns with the holes around the CPU socket on the motherboard.
3. Secure the Cooler: For Intel stock coolers, push down each of the four push-pins until they click into place. For aftermarket coolers, follow the manufacturer's instructions.
4. Connect Fan Power: Connect the CPU cooler fan cable to the 'CPU_FAN' header on your motherboard.

5. Operating Principles

The Intel Core i5-3470 processor is designed to execute instructions and perform calculations for your computer system. Key operational aspects include:

• Clock Speed: Operates at a base frequency of 3.20 GHz, dynamically adjusting based on workload.
• Quad-Core Architecture: Features four physical processing cores, enabling efficient multitasking and parallel processing.
• Intel Turbo Boost Technology: Automatically increases the processor's frequency above the base operating frequency when operating below power, current, and temperature specification limits.
• Intel HD Graphics 2500: Integrated graphics processing unit for display output without a discrete graphics card.
• Intel Virtualization Technology (VT-x): Allows one hardware platform to function as multiple 'virtual' platforms, improving manageability, security, and flexibility.
• Intel Enhanced SpeedStep Technology: Enables the system to dynamically adjust processor voltage and core frequency to reduce average power consumption and heat production.

6. Maintenance

The Intel Core i5-3470 processor itself requires minimal maintenance. However, maintaining the cooling system is crucial for its longevity and performance.

• Dust Removal: Regularly clean dust from the CPU cooler heatsink and fan using compressed air. Dust accumulation can impede airflow and lead to higher temperatures.
• Thermal Paste: If you notice consistently high temperatures or if the cooler has been removed, consider reapplying fresh thermal paste.
• Airflow: Ensure good airflow within your computer case by keeping cables tidy and ensuring case fans are functioning correctly.

7. Troubleshooting

If you encounter issues after installing your processor, consider the following common troubleshooting steps:

• No Display/No Boot:
  • Verify the processor is correctly seated in the socket and the load lever is secured.
  • Ensure the CPU cooler is properly installed and its fan is connected to the 'CPU_FAN' header.
  • Check that all power cables (24-pin ATX, 8-pin EPS/CPU) are securely connected to the motherboard.
  • Confirm RAM modules are correctly seated.
• Overheating:
  • Ensure the CPU cooler is making proper contact with the processor and thermal paste is applied.
  • Clean any dust from the heatsink fins and fan blades.
  • Verify case airflow and fan operation.
• System Instability/Crashes:
  • Update your motherboard's BIOS to the latest version, as this can improve compatibility and stability.
  • Run diagnostic tools to check for other component failures (e.g., memory tests).
