Logana, can you clarify 'some' and 'seem to'?Won't work with only the PC12800 card
Will work with a PC8500 and PC12800 card
Some mid-2010 white MacBook Unibodies seem to run ok with PC10600 ram but to run a PC12800 card you will need a PC8500 card in the other slot - the PC12800 card will run at PC8500 speed......
Yeah... as I was doing it I thought I should at least *try* mix'n'match, but didn't. I've got no idea if there are still benefits to paired RAM modules but I do intend to keep things symmetrical.some 2010 A1342 MacBooks have been reported as being quite happy with PC10600 ram but yours is obviously not one of them
It will work with at least one PC8500 module in it - the other module can be PC8500, PC10600 or PC12800 so you can save money by fitting one higher speed module since they are usually cheaper.
