Does the machine actually support 16 gig of RAM? Next, did you buy Apple compatible memory? And finally, does OS X or Windows boot or?
I venture to guess that either the system doesn't support 16 gig of RAM OR, the RAM you bought isn't fully compatible with the system. Remove 1 module and run memtest again and see if you get the same result.
yes, it does support 16gb. many places to proove that for my particular model of laptop.
yes. apple memory, purchased directly from "apple memory" section of newegg. Mushkin memory. I got the correct package.
have not tried to boot yet (OSX), due to my concern of a change of startup settings. this thought is not validated though.
