Hi iFixit community! I’m not sure if the RAM I received is bad, but I’m currently trying to upgrade my MacBook to 8GB of RAM, and it beeps 3 times upon installing the new RAM. I’m not sure if this is the issue, but the RAM I ordered is SK Hynix PC3L 12800S RAM. I would greatly appreciate any help on the matter!
You need 1066 MHz PC3-8500 DDR3 SDRAM SK Hynix PC3L 12800S RAM is not the correct RAM.
