New MacBook Pro and RAM Management

A report posted on Macrumors forum brings some information about the RAM management of the new MacBook Pro. The user indicates to have installed 2 DDR3 RAM modules of 4 GB each in a new MacBook Pro. After the installation, the notebook becomes unstable, and the system does not manage more than 4 GB of RAM.
However, according to the technical specifications, the hardware should support 8 GB of RAM without any problem, so it might indicate that Mac OS X is not set to manage more than 4 GB RAM for the moment. A similar problem was spotted with Mac Pro, and it disappeared from one day to another after an update. In addition, the same memory bug is present with the previous Penryn-MacBook Pro model if you install 2 DDR2 modules of 4 GB each.
We currently think that Apple did not implement support for 4GB RAM module as so far such modules were either not available or so highly priced that no one would install such modules in a MacBook Pro. Now with the current crisis on the RAM market, such RAM are no outrageously expensive anymore, so Apple will have to quickly implement such support as it becomes now required. Last but not least, if you install 6 GB of RAM in a MacBook Pro everything will work fine…
