RAM / Memory Modules

🧠 RAM / Memory Modules Overview

What is RAM?
RAM (Random Access Memory) is a type of volatile memory that temporarily stores data that your computer needs to access quickly. It plays a critical role in overall system performance—more RAM generally allows smoother multitasking and faster application response.

🔍 Key Types of RAM

1. DDR (Double Data Rate)

   • DDR3 – Older standard, used in many systems from 2007–2017

   • DDR4 – Current mainstream type (used since ~2014)

   • DDR5 – Newest generation with higher speeds and efficiency

2. Form Factors

   • DIMM (Dual Inline Memory Module) – For desktops

   • SO-DIMM (Small Outline DIMM) – For laptops, mini-PCs, and all-in-ones

3. ECC vs Non-ECC

   • ECC (Error-Correcting Code) – Used in servers/workstations

   • Non-ECC – Standard consumer RAM

⚙️ Specifications to Consider

• Capacity: 4GB, 8GB, 16GB, 32GB, 64GB, etc.

• Speed: Measured in MHz (e.g., 2400MHz, 3200MHz, 4800MHz)

• Latency: Lower CAS latency = better responsiveness

• Voltage: Impacts power consumption and compatibility
