Ok so i read everywhere that 6gb of ram was possible in a black macbook the last model made the summer of 2008. So what i did was 6gb worked with a 4gb and 2gb chip but i don't want to lose dual channel. So i bought 2x4gb chips installed it and got 8gb somehow to show on my laptop 
. thing that sucks is that it works for about an hour then all the sudden get really laggy and either freezes or gives me a weird power symbol. Now i know that the firmware update allowed it to go from 4gb to 6gb and I'm pushing it by installing 8gb but i don't care for the extra 2gb that i get i only put 8gb because i wanted it to have 6gb showing with dual channel. Now what I'm asking is how can i install the 8gb of ram on my mac and tell the computer to only read 6 and dump the other 2 so it doesn't crap out likes it been doing because it works fine with a 2gb and 4gb =6 but i lose dual channel and 2x4gb shows up as 8 but I'm hoping that if i tell the mac to see only 6 by either allocating 2 of them someplace else i won't have freezing problems please let me know if you guys know any solutions i know this may not make to much sense. At the end of the day i want 6gb of ram with dual channel. Nothing more nothing less.
Thanks guys
