Memory Basics

What is RAM?

Random Access Memory (RAM) is your computer's working space. It temporarily stores data that the CPU needs quick access to, including: - Operating system files - Running applications - Game assets and textures - Background processes

Types of Memory

  • System RAM: Main memory for CPU operations
  • VRAM: Graphics memory (part of GPU)
  • Cache: Ultra-fast memory inside CPU
  • Storage: Permanent data storage (SSD/HDD)

RAM vs Storage

Aspect RAM Storage
Speed Very Fast Slower
Capacity 8-128GB typical 500GB-8TB typical
Volatility Loses data when powered off Retains data
Purpose Active programs File storage

Memory Timings

Understanding Timings

Lower timings = better performance, but: - Higher speeds often compensate for looser timings - Stability more important than ultimate performance - Manual tuning can optimize both

Common Timing Sets

DDR4 Examples: - DDR4-3200 CL16-18-18-36 - DDR4-3600 CL16-19-19-39 - DDR4-4000 CL19-19-19-39

DDR5 Examples: - DDR5-4800 CL40-40-40-77 - DDR5-5600 CL36-36-36-76 - DDR5-6000 CL30-36-36-96

Performance Impact

  • Gaming: 1-5% difference between timing sets
  • Productivity: Minimal impact for most tasks
  • Memory-sensitive: Up to 10% in specific workloads

Memory Channels

Single vs Dual Channel

Single Channel (1 stick): - Half the bandwidth - Cheaper entry point - Upgrade flexibility - Performance penalty

Dual Channel (2 sticks): - Double bandwidth - Better performance - Standard configuration - Slight compatibility risk

Triple/Quad Channel

HEDT Platforms: - X299, TRX40 platforms - Professional workstations - Diminishing returns - Complex troubleshooting

Memory Slots

Installation Priority: - 2 slots: A1, B1 (usually) - 4 slots: A2, B2 first, then A1, B1 - Check motherboard manual - BIOS will show detected configuration

Overclocking

XMP/DOCP Profiles

XMP (Intel): - Predefined overclocking profiles - One-click enablement - Manufacturer tested - Warranty coverage

DOCP (AMD): - AMD's XMP equivalent - Same functionality - Platform-specific naming

Manual Overclocking

Steps: 1. Start with XMP profile 2. Increase frequency gradually 3. Adjust timings if needed 4. Test stability thoroughly 5. Stress test for hours

Overclocking Benefits

  • Performance Gain: 5-15% in memory-sensitive tasks
  • Gaming: 1-5% FPS improvement
  • Productivity: Variable impact
  • Learning: Understanding system limits

Compatibility
