COMPTIA A+ Practice Exam

A PC3-8500 DIMM has 240 pins. This type of memory module belongs to the DDR3 (Double Data Rate Type 3) SDRAM family, which is designed to provide higher bandwidth compared to its predecessor, DDR2. The 240-pin configuration is a standard for DDR3 memory modules, allowing them to accommodate the necessary electrical connections for data transfer, power, and management signals.

Understanding the pin count is important for compatibility with the motherboard. Since DIMMs with differing pin configurations cannot physically fit into a slot designed for a different standard, knowing that PC3-8500 DIMMs require 240 pins ensures that users select the correct type of memory for their systems, maximizing performance and stability.
