What are the specs on the memory? Size & speed?įYI, the memory slot nearest the bottom case tends to have a high rate of failure since the solder joints tend to break after years of the bottom case pressing against the Logic Board and the memory slot. How long have you have you been using these memory modules? You do need to be very careful to only press on an open area near the edge of the module or you can damage the extremely small surface mount components on the memory module.Īlso make sure the small triangular protrusions on each plastic arm haven't become worn and are holding each side of the memory module in place.Īre these original Apple memory modules or a third party memory upgrade? Macs can be very picky about the memory they use so it is best to use only memory from Crucial or OWC for best compatibility. I like to use a non-metallic tool such as a nylon stick or a wooden toothpick to press on the edge of the memory module nearest the keyboard to make sure it is latched into place after installing the second module. Many times when installing the second memory module the first one can become unlatched since both modules are latched using the same plastic arm. Make sure both modules are securely latched in place. ![]() ![]() I couldn't tell for sure from your post if you had done this already.
