Hi. I'm having trouble with a previously reliable system I built 2 years ago after trying to double the RAM from 6GB to 12GB (3 new identical G-Skill F3-12800CL9T-6GBNQ 2GB sticks same as original 3). It will still boot into Windows 7 showing all 12GB but no matter what I do (setting Lion to boot into 64 bit mode, editing DSDT, chameleon plist, etc..), it always freezes at the gray Apple with the MB showing POST code 73. Oddly enough, when I open CPU-Z in Windows, it will show the new RAM as it is correctly listed (PC3-12800) but the older RAM is all listed as PC3-10700) while the part number for all 6 is F3-12800CL9T-2GBNQ - NOT 6GBNQ like on the package and the stick labels. Any ideas? 
Thanks in advance for any help.
