Possible to have too much Memory?
Hello.
I have been getting the dreaded image buffer with my 8000X5333 Comp that I am panning and scanning in my 720X480 Comp. I have tried all the workarounds on the web, tweaked all the settings, spent the night searching for answers…and today I have decided to just buy more memory.
So, I was curious if it is possible to buy too much? What seems to be Optimal for After Effects 7?
I am running a: 4X2.5 G5 with 4Gig of DDR2 SDRAM I am thinking of going up to 8 Gigs.
Any thoughts?

In After Effects, hold Shift, go in Edit > Preferences > (Any preferences) > Scroll down the menu and click on Secrets/Shecrets. Look at your settings.
I really really recommand you to look at Aharon’s tutorials (about Nucleo and workflow tips) if you click on his head at the top of the After Effects forum page.
Good luck.

I have seen his 2 part tutorial, and unfortunately tweaked the setting in the “secret” prefs. After all of those tweaks….I was able to click my Comp to Full Res. but still got an error message when I tried to do the render cue.
I should say that when I lowered my Memory Cache to around 40% (It failed at 60) it seemed to be working, but was going to take 13 hours!
Do you not think adding memory will help?

AE can’t address more than 3GB of RAM in any working environment. Your OS usually wants to hold on to 1GB for itself, so more than 4GB of RAM will only really benefit you if you’re running AE and other RAM intensive programs at once.

Thank you. Thats really great to know. I never run other programs while I am in After Effects so doesnt seem as if buying more Memory would help the problem.

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.

I’ve read some very deep articles on the whole 32bit v. 64bit issue and although my understanding is far from complete I thought that a 32bit app couldn’t address more than 4GB of RAM even if running in a 64bit OS. Although said 32bit application could benefit from an efficient 64bit OS implimentation (OS 10.5?)
Any info would be helpful =)

Apparently CS3 will act rather like Nucleo, in that when you’re rendering or previewing it will fire up several instances of AE (each using upto 4GB) so on a 64bit OS even AE7 (with Nucleo) will use all the RAM you can throw at it..
The caveat is that the extra RAM won’t enable you to preview anymore *duration* of the comp, it will just preview that same amount faster..if that makes sense?
So, say with 4GB ram you can preview 30seconds of a particular comp at full res. If you have 16GB RAM you will still only be able to preview 30secs at once, but it will render the preview way faster.
Steve Forde will no doubt correct me if I’m wrong, but that’s the jist I got.

Finaly getting my head around all this technical gubbins then – phew!
There was a time a couple of years ago when to me a PC was just, well a PC and my world was my Quantel Paintbox that had full tech support and I didn’t know how anything worked! Well that thing is like a baby’s Photoshop Elements with SDI in/out these days!…Anyone want to buy it?
It’s ten times more satisfiying knowing what’s going on under the hood, being able to tweak it yourself reasonably cheaply and more importantly explain to a client when they say “why is that JUST THE WAY IT IS?!?”
