How To Clean Your Ram Slots

Got a donated G5 20' iMac with several problems. After replacing power supply, it began to work. Then tried to add RAM (matching chips), but top (2nd) slot doesn't work. With RAM in 2nd slot, iMac experiences constant kernel panics.

How To Clean Ram Laptop

A Proper Way to Clean a RAM Stick. A lot of people just dump their computer’s memory stick, just because it isn’t working while testing their computer with a new RAM. Believe it or not but if you are having a brand memory plugged into your computer, then there is only 2% to 3% chance that you’ll lose your memory stick and need to buy a new one.


Original suggestion from multiple sources said it was likely logic board problem, but this Mac is too old to put money into that. Since it's 6 years old, and the 2nd RAM slot was never used, IS IT POSSIBLE that the RAM slot merely needs cleaning? (One tech guy suggested cleaning connectors on the RAM itself with an eraser, but since it was new and clean, I wondered about the slot itself.)

Can the RAM slot be cleaned safely? If so, what should I use? (Alcohol or other cleaner? How to apply if any cleaner can be used? Or is there something like a pencil eraser that could go into the inside of the slot?)

Is this a good question?

How To Clean Ram Memory

To remove memory modules, or RAM, from a laptop, you follow very similar steps from one brand to another; today, nearly every laptop design places an access panel on the bottom of the laptop and uses similarly latching sockets. The description used here is for the Toshiba Satellite P205 laptop.

You first want to make sure that the laptop has no electrical power and is cool and stable. Take these steps:

  1. Turn off the computer using the Windows shut-down process.

    Keep in mind that you lose stored data if you use Sleep or Hibernation mode.

  2. Unplug the AC adapter cable that runs to the laptop.

    Why remove the AC adapter and the battery before removing memory modules? First of all, plugging them in while power is on could result in damage to the RAM. Secondly, doing any work on a laptop while power is applied could result in a damaging spark.

  3. Remove the battery.

  4. Disconnect any other cabling to the laptop, including an Ethernet cable or a telephone modem wire.

    If the laptop has been running recently, allow it to cool for about 15 minutes; memory modules can become quite hot when they are in use.

  5. Locate a small Phillips-head screwdriver.

    This is the screwdriver with an X-shaped head.

  6. Place a soft cloth or other protective mat on a desktop.

  7. Turn the laptop over so that its bottom is facing up.

  8. Locate the memory module slot cover.

    The illustration above shows the proper technique for removing the memory module slot cover on the bottom of a laptop.
  9. Carefully remove the screw that holds the cover over the memory compartment.

    Hold the screwdriver at a right angle to the bottom of the laptop and turn the screw carefully; it shouldn’t require a lot of force to remove. Once the screw is removed, put it in a safe place. Use a piece of clear tape to attach it to the desktop or the side of the computer.

  10. Ground yourself before touching the memory module.

    Touch any grounded metal surface, like a light stand, or touch the center screw on an electrical outlet.

  11. Carefully release the latches on the side of the module holder.

  12. Lift it to an approximately 30-degree angle from the bottom surface of the laptop.

  13. Gently slide the module out of its connector and out of the slot.

    Lift up the memory module holder and remove the memory.
