So, I did a little sleuthing to try to find modules that are as close as possible to what Apple installs. Short version: I'm buying the
Kingston KVR1333D3SOK2/8GR.
Long version: I first checked the
iFixIt teardown and grabbed the model number off the SO-DIMM in the photo (Hynix HMT325S6BFR8C). I then found the
datasheet for that module, which lists the model numbers of the actual chips as H5TQ2G83BFR. I then zoomed in on images of modules at Newegg until I found the Kingston one mentioned above, which seems to have the exact same chips.
Of course, the Kingston module is different in that the board itself was manufactured by Kingston and not Hynix, for all I know the chips may be from a higher or lower-quality bin, maybe the Kingston module I receive will use different chips, etc. But I'm betting this module will be pretty darned similar to what Apple uses. In reality, any cheap module will probably work flawlessly, but I guess the paranoia got the better of me.
