    I am building my Mac Pro, I want to have 3 X4GB ddr3 memory on my Mac Pro.
    I know this is ECC memory and Registered, and Mac Pro uses unbufferred ECC.
    Can some one confirm me if Mac Pro can be put with it (as the below linked ebay item)? From the searched threads, some said yes with speed penalty, but he points to a wikipedia page to explain the speed difference could caused, not confirmed based on experience though. I am not concerned with the speed difference, if there is but minimal. Cost is my concern. I wanted to know if those DRAMs work fine in 2009 Mac Pro. Any body tried before?

    Can't confirm that those specific DIMMs work. However, there is no reason they shouldn't work. Registered memory does work on 2009 Mac Pros, this has been confirmed by multiple sources. 8GB modules are all RDIMMs.
