    I have two 8's right now. I'd like to upgrade for a total of 32. I have two questions:

    1. Is it always best to keep all memory modules from the same manufacturer? Or can I just add two more 8's that are from a different manufacturer?

    2. Any opinions regarding memory purchased from OWC?

    What jgo said. I ordered 16gb (2x8) from owc. The system now shows 24.

    You can get less expensive RAM (and possibly better timings) going with someone else than OWC. Look for Crucial on Amazon or Newegg
