🎯 Learning Intention

I will explain how different RAM generations, channels, voltages, and error-correction methods impact system performance and troubleshooting.

✅ Success Criteria

• I can compare DDR3, DDR4, and DDR5.
• I can explain why dual channel improves performance.
• I can identify the difference between ECC and non-ECC memory.
• I can recognize common symptoms of memory failure.
