Study Notes
Memory Troubleshooting
-
Memory Failure Causes:
- Power spikes from the electrical grid
- Improper handling (static discharge)
-
Memory Error Symptoms:
- System lockups
- Blank screen after POST
- Operating system boot failure
- Blue screen errors (intermittent)
-
Memory Error Causes:
- Hardware: Faulty memory modules
- Software: Poorly written applications accessing bad RAM addresses (leads to intermittent errors and blue screens)
-
Blue Screen Error Analysis (Windows 7 & Earlier):
- Useful information about the memory address causing the error
- Changing address suggests application error
- Constant address suggests faulty memory module
-
Blue Screen Error Analysis (Windows 8 & Later):
- Minimal information provided, hindering diagnosis
Testing Memory Modules
-
Method 1 (Removal):
- Temporarily remove memory modules one at a time to pinpoint the faulty module (time-consuming, especially with intermittent problems)
-
Method 2 (Testers):
- Hardware Testers: Dedicated hardware devices with memory slots for testing, reporting module health
- Software Testers: BIOS/UEFI-integrated testers or external software running from a minimal OS (e.g., on CD/USB)
Memory Installation Issues
-
ESD Protection:
- Use anti-static bags and mats
- Ground yourself with a static wrist strap when handling memory modules
-
Improper Seating:
- Ensure memory modules click fully into their slots using both connector tabs
-
Memory Compatibility:
- Check motherboard's supported memory speed (e.g., DDR3 1066, 1333, or 1600 MHz):
- Install the fastest supported speed for best performance
- Dual-/Triple-/Quad-Channel:
- Ensure identical modules are installed in designated slots
- Color-coding on motherboards often indicates correct dual-/triple-/quad-channel configurations
- Verify dual-/triple-/quad-channel operation in BIOS/UEFI
