Who said that nothing good can come from breaking the rules? Apple’s specs for the Intel Core 2 based MacBooks state clearly that the computer supports up to 2GB of RAM via a pair of 1GB chips. But after extensive testing in the Skunk Works over at OWC (Other World Computing), it turns out that the MacBook can support just as much memory as its big brother, the MacBook Pro!
Apple claims that systems using the GMA950 graphics chipset require memory modules be installed in equal pairs. Apple indicates that a massive performance hit is the result of unmatched memory. But in OWC’s testing, this proved rarely to be the case. In fact, in most tests there was a negligible performance penalty when running odd memory configurations.
With this is mind, the next logical question would be the MacBooks support for a 3GB memory configuration. That was the next test the OWC lab rats decided to run. Not only did the MacBooks boot with a 2GB and 1GB chip running in tandem, but the memory was also properly addressed by the operating system!
So now that the MacBook can boot and address 3GB of RAM, the next thing to test was performance. Though specific benchmarks have yet to be posted, my source tells me that the MacBooks perform just as well in a 3GB configuration as they did with 1.5GB.
Not only is the MacBook a powerful and economical dual core notebook, but it turns out that it can sport just as much memory as the top of the line MacBook Pro. And with modern applications consuming more and more memory, it becomes more and more advisable to add as much memory as possible to any computer that does heaving lifting.
