RAM (Random Access Memory) is one of the easiest and most impactful PC upgrades. Proper installation is crucial for stability and performance. This guide walks you through how to correctly install RAM in your PC and avoid common mistakes.

Step 1: Know Your RAM Type
- Modern systems use DDR4 or DDR5 RAM.
- Check your motherboard’s manual for compatibility (type, speed, and max capacity).
Step 2: Power Down and Prep
- Turn off your PC and unplug it from the wall.
- Press the power button once to discharge remaining power.
- Use an anti-static wrist strap or touch metal to ground yourself.
Step 3: Locate the RAM Slots
RAM slots are long slots next to the CPU socket, usually labeled DIMM1, DIMM2, etc. Most boards have 2 or 4 slots.
Step 4: Check the RAM Orientation
- Line up the RAM notch with the slot divider — it only fits one way.
- Don’t force it in backwards.
Step 5: Insert the RAM
- Push back the locking clips at the ends of the slot.
- Hold the RAM by the edges and push it down firmly into the slot.
- Apply even pressure until the clips click back into place.
Tip: You may hear or feel a soft “click” when it's seated properly.
Step 6: Dual-Channel Optimization
For best performance, install matched RAM sticks in the correct slots:
- Use slot 1 + 3 or 2 + 4 (usually color-coded).
- Refer to the motherboard manual for correct dual-channel pairing.
Step 7: Boot and Check Detection
- Turn on the PC and enter BIOS/UEFI.
- Ensure the RAM is recognized and running at full speed.
- You may need to enable XMP/DOCP in BIOS for higher speeds.
Step 8: Verify in OS
# Windows
Ctrl + Shift + Esc → Performance tab → Memory
# Linux
free -h
Troubleshooting Tips
- PC won’t boot? Try reseating RAM or trying one stick at a time.
- RAM not running at advertised speed? Enable XMP or update BIOS.
- Mixing different brands/speeds? Stick with matched kits for best results.
Next Steps
Now that RAM is installed, you’ve boosted your system’s multitasking power. Consider running a memory test (e.g., MemTest86) to ensure stability, especially with new or overclocked kits.
