Memory installation troubleshooting tips

 

Diagnosing the Problem

 
  • If the symptoms started after you recently added more memory, the new module could be faulty.
  • Your computer may produce multiple beeps or a continuous beep when you turn it on. These beeps can indicate many different problems, including being a symptom of bad RAM.
  • If you are not comfortable fixing your computer yourself, I recommend taking your computer to a Apple store.

    Fixing the Problem

     

    Press harder when inserting modules into the memory slot.

    Make sure the notches in your module are lined up with the keys in the slot, then press down using 20 to 30 pounds of pressure. While this may seem like a lot of force to use on a small module, it's necessary to properly "seat" the module. If installed properly, the clips on the side of module should snap into place on their own and a thin portion of the gold pins — 1/16th of an inch or less — should be visible (about the width of a line of pencil drawn on a piece of paper).

     

    One memory module one at a time

    Take both RAM out. Use one stick of RAM at a time, if it beeps or causes crashes, remove and set aside and then repeat for 2nd RAM. Once you have found out which stick is causing the problem, we can arrange for a replacement. When you find the sticks that are bad you can order replacements. It is possible all the memory modules are damaged if your computer experienced a serious power surge.

     

    Swap memory slots

    It is possible that a memory slot is failing. Try testing each memory module in each of the memory slots to find if one of the slots is faulty. To fix a faulty slot you would need to replace your motherboard.

     

    Double-check internal cables

    Did you accidentally bump one of the wires or cables inside your computer while you were installing your modules? A loose hard drive cable can prevent your computer from booting up properly. Make sure all cables are firmly lodged in their sockets.

     

    Failing Power Supply

    Random reboots can be cause by a failing power supply.

     

    Dirt and Dust

    Dirt and dust can also cause issues that look like memory problems. It is a good idea to clean dust out of your computer with a blower or a brush at least once a year, more often if you have furry pets.
