Are you asking in the context of AE CS3 Multiprocessing or NP2? If it’s CS3 then I’m afraid any response I give would be mostly speculation. It’s probably best that someone from Adobe address these concerns.
That said, I’m not aware of any egregious lag issues with NP2’s preview so I will assume you are referring to AE CS3. If indeed NP2 is suffering from this, I’d like to get my hands on a sample project and have the problem fixed as soon as possible. Please let me know.

Imagine getting back preview results that didn’t jive with the layers and animation defined in your comp. That would certainly cause head-scratching and possibly fits of rage.
Saving the project is a necessary artifact of the multiprocessing approach. I’d guess that AE’s MP would likely suffer from this also – but there I go … speculating… 😉

Hey Mike,
The issue with intermittent color bars when referencing QT footage is a known problem with MP in AE CS3. Adobe is working on a fix. We have seen this happen with NP2 from time-to-time in CS3 also but we have put in measures to minimize its occurrence.
Hang tight, the AE team is on top of it.

If you are not using multi-processing (either from Nucleo or AE CS3), I’d suggest that you tweak your memory prefs in AE.
The default setting for image caches is 60% of physical RAM. It sometimes happens that your renders hit a point in the comp where the frame size is huge or the amount of cached data peaks to some crazy level where the default limits get exceeded.
I’d try bumping that 60% number up to say 90% and see if your renders get any further. (you don’t need to change the one that’s set to 120% – just leave it)
Even if this works, I’d still recommend dropping it back down to the default once you get through this crunch.
If you ARE using multi-processing – forget everything I just said ’cause the rule change in that case :).
Hope this helps,

True, CS3 can give you improved performance for previews/renders, it does not allow you to do background or speculative previews/renders.
Having peaked processors is nice, but being able to go back to work while you’re rendering, that’s where the real power is. That’s the message we get from our users.

I wish I had an answer for you. Could you please send this question to our support team (support@gridironsoftware.com) and we’ll have look to see what’s going on.
I assume you’re at 29.97 fps, no fields/pulldowns?
Anyway – I’ll be sure to post the resolution once we find it.

Yeah, my first suspicion was that it was fear-mongering, planting a seed of doubt in would be do-it-yourselfers. No way to know for sure but try it. It won’t be me though.

Actually,
It will depend on whether you’re running a 32 or 64 bit OS. If you’re running 32bit XP for instance, the OS will be able to recognize up to 4GB total (minus some for OS function and PCI express “blackhole”). AE 7 alone on a 32 bit OS can recognize up to 3GB (with some persuasion. i.e. using the /3GB switch in the boot.ini)
On a 64 bit OS the skies the limit if you are using Nucleo/NucleoPro or AE CS3. Both force AE to run multiple instances with each instance able to access its maximum memory(which I think is 3GB on both 64Win and OSX).
If you’ve got multiple cores and a 64bit OS – go nuts on the RAM.

This link might be of interest. It basically says the memory and drives for your quad might not work when attempting to upgrade to 8 cores.

Oh yeah, some links might be helpful.

I’ve seen Trapcode Echospace cause that. I think they have a patch available for it.
