Giving this a bump. I have the similar specs, 2x3Ghz Quad-Core Intel Xeon, 8GB RAM, Mac OS 10.5.2. I can’t get more than an hour into work and I’m down to a 2 frame RAM preview, or the “can’t allocate space” for a 900 image comp sadness when I try to render out.

Setting my RAM Cache Size to 40%, enabling a disk Cache, none of this helps much. Also, I’m on Leopard now, and it seems worse than Tiger. Any ideas?
