The Best Way To Clean RAM Contacts

Keeping your computer’s RAM clean is crucial for maintaining system stability and reliability. In this guide, I’ll share a trusted method I’ve used for over two decades to clean RAM contacts effectively, applicable to all types of memory modules and add-in cards.

Essential Tools for Cleaning RAM

Before you begin, gather the following tools to ensure a safe and effective cleaning process:

  • Phillips screwdriver
  • High-quality pencil eraser (such as Faber-Castell)
  • Lint-free cloth
  • Compressed air or an air compressor
  • Ground wrist strap (optional, but recommended for avoiding static damage)

Step-by-Step Guide to Cleaning RAM Contacts

Step 1: Prepare Your Workspace

  1. Power Down and Unplug: Ensure your computer is unplugged and all cables are disconnected.
  2. Reduce Static Charge: Touch the metal case of your computer to discharge any static electricity from your body.
  3. Open the Case: Remove the lid of the case. If your computer is dusty, clean the inside first to avoid contamination during the RAM cleaning process.

Step 2: Remove and Clean the RAM Modules

  1. Remove the RAM: Carefully release the clips at the ends of the RAM slots and gently pull out the RAM modules. If a clip doesn’t move, be extra cautious as it is designed to be fixed.
  2. Clean with Eraser: Place the RAM on a clean, flat surface. Gently rub the contacts with the pencil eraser in short strokes until they appear clean. Flip the RAM and repeat on the other side.

Step 3: Remove Eraser Residue

  1. Wipe the Contacts: Using the lint-free cloth, wipe the RAM contacts thoroughly to remove any eraser filings.
  2. Use Compressed Air: Blow off any remaining debris with compressed air. Tap the RAM module gently on a flat surface to dislodge hidden filings before the final air blow.

Step 4: Clean the RAM Slots

  1. Air Blow the Slots: Use compressed air to clean out the RAM slots thoroughly. Ensure all dust and debris are removed, checking closely with a good light source.

Step 5: Reinstall the RAM

  1. Check and Align: Ensure the RAM slots and modules are clean and free of debris. Align the RAM module with the slot, taking note of the notch position.
  2. Insert the RAM: Carefully press the RAM into the slot until the clips click into place, securing the module.

Common Mistakes to Avoid

  • Avoid Touching Contacts: Never touch the RAM contacts with your fingers, as oils and static from your skin can damage them.
  • No Solvents: Do not use solvents or sprays on RAM contacts, as these can corrode or damage the delicate metal.
  • Thorough Cleaning: Make sure to remove all eraser residue; leftover particles can cause connectivity issues.


Cleaning your RAM contacts can significantly reduce the need for replacements and improve your system’s performance. By following these detailed steps and avoiding common pitfalls, you can maintain your RAM effectively and ensure your computer runs smoothly.
