Chosen Solution
MacBook Pro Mid 2010 13" Unibody I’m trying to upgrade from 4GB RAM to 8GB RAM. I bought two 4GB sticks from iFixit, followed the iFixit install instructions, and upon restart, it appeared as if the swap had worked. Going into About tab I can see that the computer is recognizing the new sticks, but shortly after starting the computer, horizontal colored lines filled the screen, the computer froze, and then shut off. I tried turning the computer back on, but couldn’t make it past the log-in screen before the lines showed up again. I took out the new RAM sticks and put back in the old 2GB sticks, and this fixed the issue. Any ideas on how I can upgrade to 8GB successfully? Is there a step that I am missing? I am in a pickle here; I need to upgrade to 8GB since one of my school’s software programs is no longer working on my computer, since their last software update. I was told that Lockdown Browser now requires 4GB of available RAM in order to facially recognize the test taker. :(
You likely put in the wrong RAM. This series uses the main RAM for video RAM. This model has a “48 core” NVIDIA GeForce 320M that shares memory with the system. Reference: 13" MacBook Pro 2.4/2.66 Core 2 Duo (Mid-2010) Make sure you are using 1066 MHz PC3-8500 DDR3 SDRAM. You may want to put back your original RAM to make sure nothing else got damaged.
