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......
Logana, can you clarify 'some' and 'seem to'?
I've recently acquired an A1342 with 2x2GB PC3-8500, and want to take it up to 8GB. Looking at online configurators, Crucial sticks by Apple's original '4GB max' whereas Kingston seems to deny the existence of the 2010 Macbook altogether.
Out of idle curiosity I have *just* tried fitting the 2x4GB PC3-10600/1333MHz from my Mini. The MacBook tells me to beep off.
If I want 2x4GB that is 'guaranteed' to work in an A1342, regardless of any secret little parts changes/tweaks that occurred during the production run, do I need to stick with PC3-8500/1066MHz?

EDIT: Dabs appear to have the
right stuff, although I can't trace it back to Crucial's own website. Price looks about right in these expensive times (the Crucial 2x4GB kit for the Mini cost me £33.79 including VAT/shipping 22 months ago!). I guess there's no point looking at non PC3-8500 in an attempt to save a few quid...
