Just got a older Mac Pro 2 2.66. It has 2 banks of 512, 4 banks of 1gb and 2 banks of 2gb.


Is this ok? I thought it was better to have all the same size in the machine.


Photoshop cs6 is running really slow on large files 350mb. Plus I need to upgrade the

video card it only has 256.. need to go to 1gb. Running Lion.


Anyway Thanks

    8x2GB or more.


    Quad sets (4x1GB and 4x2GB) minimum


    A "bank" is all of the DIMM slots on one channel or Riser.


    Dump the 512s


    A set of 6 DiMMs is not symmetrical


    Amazon has 2x2GB FBDIMM 667s $39 which is why I (and others) have gone.


    4GB FBDIMMs (as in 2x4GB set) cost too much

  has a lot of good tips about CS6.

    They are top quality brand name... not a big market of us using older Xeon FBDIMMs.. who knows. I wouldn't be using and recommending if I wasn't okay with them. And I've seen a ton of issues with OWC and having to exchange now with FBDIMM issues on 1,1 thru 3,1 models.
