Description

1. Desktop Tower PCs:

For desktop PCs, DDR3 RAM comes in a form factor called DIMM (Dual Inline Memory Module). A 4GB DDR3 DIMM module would typically be 240 pins and is designed to fit into a desktop motherboard’s memory slot.

• Key Features:
  • Type: DDR3
  • Capacity: 4GB
  • Speed: Common speeds are 1333 MHz, 1600 MHz, or 1866 MHz
  • Voltage: Typically 1.5V or 1.35V for low-voltage modules

2. Laptops:

For laptops, DDR3 RAM uses a different form factor called SO-DIMM (Small Outline DIMM). A 4GB DDR3 SO-DIMM module would usually be 204 pins and is designed to fit into a laptop’s memory slot.

• Key Features:
  • Type: DDR3
  • Capacity: 4GB
  • Speed: Common speeds are 1333 MHz or 1600 MHz
  • Voltage: Typically 1.5V or 1.35V for low-voltage modules

Compatibility Considerations:

• Form Factor: Desktop PCs require DIMM modules, and laptops require SO-DIMM modules. They are not interchangeable.
• Speed: Ensure the RAM speed is supported by your system. Most systems will downclock the RAM if the speed is higher than what the motherboard supports, but it’s best to match the speed.
• Voltage: Match the voltage with your system’s requirements. Low-voltage RAM (1.35V) is often more energy-efficient.
