According to Apple, the mid-2010 MacBook (not MacBook Pro) will support a maximum of 4GB of memory.
Are there any more authoritative references to more than 4GB of memory working in this model of MacBook?
What is the safe and cheap path to verify this myself? Can I get a single 4GB chip, replace one of my 1GB chips and see if the supported total memory is 4GB or 5GB? Worst case I've just bought the maximum 4GB, best case I prove that it can take more right?
