I bought a 2.4GHz mid 2010 MacBook Pro logicboard on eBay. Upon installing RAM, the computer beeps every five seconds indicating it doesn't detect RAM. I used standard 8500s 1066MHZ RAM with 8 modules on each side of the chip (2Rx4?). The seller claims the board will only work with RAM that has 4 modules on each side of the chip (1Rx4?). I guess the terminology here would be 1Rx4?
The RAM is good because both chips worked in an A1342 MacBook.
I understand Macs are particularly sensitive to RAM clock speeds and such but I'm concerned I bought a bad board. Any ideas? Thanks.
