How To Clean Your RAM Contacts Properly

By Marlo Strydom

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 on how to clean RAM contacts effectively. This method also applies to all types of memory modules, add-in cards, and anything else with an edge connector.

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 On How to Clean 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 delicate metals.

  • Thorough Cleaning : Make sure to remove all eraser residue; leftover particles can cause connectivity issues.
