Why 8GB RAM upgrade failed? (Computer sees only 4GB)
So I've decided to put 8GB RAM instead of 2GB available on start in my Macbook Mid-2010 A1342 (White). After reading this page: What is the maximum RAM for a MacBook Unibody A1342?
as one user suggested it should work I put:
2x Kingston 4GB SODIMM KVR1066D3S7/4G, rated 1066MHz into My MacBook. It sees only 4GB after boot. Bank 1 is filled and Bank 0 is empty. I checked each RAM separately in the bottom bank and it works. In upper bank it gives just beeps. No clue what went wrong - I see lots of stuff that people are capable of making A1342 8GB RAM machine.
Please help me!
