The memory problem occurred about two years ago. Apple released a 
memory firmware that, many people found, disabled some or all of their 
add-on memory modules. It turns out that the new firmware included a 
test to ensure the computer's memory complied with Apple's specs, which 
sounds ok, but many third party-memory modules that had been working 
were now shown to be below-spec and therefore disabled.

Most reputable vendors replaced any modules that had been disabled by 
the new firmware test. (I had used OtherWorld Computing,

anymore, and a link to DIMM First Aid, which is available and may help.
