About 2 months ago, I upgraded my 17" MBP 8,3 to 16GB of RAM.  The exact specs are:

  • 2 x Super Talent DDR3-1333 SODIMM 8GB Value Notebook Memory


The laptop works GREAT with the RAM installed, except for one crucial scenario.  When I try to boot my 10.6 install DVD (hooked up via external USB superdrive), I get the 3 beeps signalling bad RAM.  The thing is, the computer runs fine when it's in 10.6.8, and it recognizes all 16GB of RAM.


I've tried with my external superdrive (removed to install an SSD) and with an install boot USB (created with the 10.6.3 install DVD and Disk Utility).  It will boot to a USB hard drive with a full OS installed on it, just not the install DVD (or USB).


Has anyone else had this issue and solved it?  I know 16GB is not officially supported by Apple for the MBP 8,3; but there has to be a way to have my cake and eat it too.  Thoughts?
