Hello hi, I have a 2009 Mac Pro, 4.1, I've updated the firmware so it how shows as Mac Pro 5.1 under "About this Mac". I have 20gb of Ram at DDR3 ECC 1066MHZ 4GB x 4 and 1 GB X 1 Question 1) any benefit in going to 1333MHZ Ram ? 2) or just add more RAM overall and it will be better ? "Sharing is Caring" section ================= I used to doing 3-5 minute videos, and hardly see the RAM usage go over 10gb. Now I just got a series of videos that are 30 to 45 minutes long and I can see that RAM is completely used up. thanks.
