Thanks! sorry I didn't look harder. I have been having other issues with CS4 so I wasn't sure if it was symptomatic of a larger issue. Wish I would sprung for the 32GB instead of the 16GB of RAM!! Dang!!
That's a pretty big frame size. Tiling would be a good approach.
Hopefully, with the advent of CS5 (64-bit) and a true 64-bit OS, these memory limitations won't be an issue.
I also am running a ridiculous number of layers, 3d objects, lights, you name it. I am suprised there is not smoke coming out of the sides of the machine. I took my machine into Apple and they said that one of the video cards was bad. Is it possible that I could have fried it out because the RAM settings were wrong in AE? I'm not going to tell them that.......just curious.
So Apple will have to update there OS to 64 bit too to take advantage of CS5? Let's hope they are on it...
Snow Leopard is already out!
I really doubt that your RAM settings in AE could have fricaseed your video card in any way, shape, or form.
There's not much you can do to wreck a card from the software end on a Mac unless you have some 3rd party utility that lets you overclock and/or overheat your GPU. I don't even know if those exist on the Mac (they might, but I've never needed to look for one).
It's more likely that there was a problem with it initially, a power spike/drop kicked it's butt, or it's poorly seated on the mobo.
So I just realized that my RAM settings were set to use only 2GB per core, with only 5 cores being used. Still getting the same message....any suggestions besides breaking the comp down to smaller parts? Does it make sense that things run smoother when the computer is just turned on/restarted then after it has been used for awhile. I just imagine the heat sinks on the RAM glowing red in there. I'm giving her all she's got, captain.....
2 GB/core is the minimum that any core should be allocated.
If you fed all of your cores 2 GB, then you'd starve your system.
Todd Kopriva has posted an excellent article about this on his blog.
If you think you have bad RAM, there are some tools out there to test your hardware (do some googling).
It sounds like, from your initial post, that you experienced a pretty bad crash early on that seems to have negatively affected overall performance.
Have you tried uninstalling, running the clean scripts, and re-installing? This won't address the large composition issue, or mimic the effect of some more RAM, but it may help overall stability.
I had already read the article, but I must not be understanding something. If I have it set to use 2gb per core and it's only using 5 cores, plus 2gb for other applications, that is 12GB of RAM, I have 16GB on my system. I lowered the minimum RAM per core to 1GB, because the Adobe site recommends that as a base setting for andHD project and I am actually getting longer RAM previews then with it at 2GB, though they seem to take a lot longer to load in. Am I backwards on something here? Also, if it is an dual quad core system, there should be 8 cores, but in the multi-processer preferences panel it lists CPU's as 16. Please excuse my ignorance. Thank you for all of your help and the timely responses.....

When you say "the Adobe site recommends", what exactly are you referring to? If you're quoting recommendations written for After Effects on the Adobe website, you're very likely quoting me. And this is what I wrote in the Help document:
"The amount of RAM required for each background process varies depending on your system configuration; at least 1 GB per process is recommended. Optimum performance is achieved with computer systems with at least 2 GB of installed RAM per processor core."
This blog post gives essentially the same advice, but with more explicit suggestions.
But, as I say at the bottom of that blog post, if you find that some other settings are working better for you, that's great. Every project and computer system are different. Do what works for you.
> Also, if it is an dual quad core system, there should be 8 cores, but in the multi-processer preferences panel it lists CPU's as 16.
The number of "virtual" processors can be double in a system that uses hyperthreading. After Effects doesn't actually treat these as separate processors in this context, though.
