After Effects Memory and Multi-Processing Advice
on Feb 22, 2010 at 4:36:57 pm

Hello I'm new to this forum and I like to ask a question, I'm sure, however, its been asked before. Here it goes:

I'm relatively new to After Effects CS4, I'd would like to know if I'm making the best of my computers ability. Don't get me wrong I've read numerous instructions on the subject and it can get a bit confusing.

I run a Q9500 overclocked to 3.40ghz with 8gb ram -Windows 7 [64bit]

Memory and Multi-Processing settings:

Total AF usage: 7.5GB
Ram to leave other applications 0.5GB

Render multiple frames simultaneously [Ticked]

Minimum allocation per cpu [0.5] should this be higher?

Foreground memory: 1.4GB
Background memory: 6.1GB

1.52GB per cpu

I've also enabled disk cached at 8GB

and turned off enable open GL

I'd be graftful for any tips or advice since I've had the dreaded 7:66 error code once or twice.

Thanks Bob.

At least 2 GB of RAM per core. AE can use up to 4, but 2 is the absolute minimum you want.

Thanks Michael, just to make it clear to my own reasoning did you mean increase it from 1.52GB to 2GB? or did you mean increase the minimum allocation per cpu [0.5]setting to 2GB?

Regards Bob

I would increase the minimum allocation to 2 and tell it to use one less core or whatever you have to do to make it use more than 2 GB per core.

[Bob Crampton] "Any other suggestions are welcome."

Buy more RAM. The current version of AE can (with a 64 bit OS) use up to 4 gigs per process. The new version coming out (CS5/After Effects 10.0) will be a fully 64 bit program. It will probably be able to use tons more than that.

Buy more ram LOL my motherboards limit is 8GB! and I have a 64bit OS already (thats something!). I wish money grew on trees.

Thanks Bob

[Bob Crampton] "I run a Q9500 overclocked to 3.40ghz"

Who makes this processor? AMD or somebody? You may want to double-check that AE will even work with this processor first.

I made that mistake: now I have a Windows box with AMD processors, and I can only open up half of my CS$ applications. It sucks.




[Bob Crampton] "Ram to leave other applications 0.5GB "

Um, you might want to be a little more generous to those other applications. I'd go 1GB minimum.

You already have heard about RAM. Know this: AE is the ULTIMATE RAM hog.

Hello Dave its a CPU Intel 12MB Cache, 45nm and yes it runs After Effects CS4 95% no problem. I'll try that 1GB minimum you recommend.

Dave does it matter what graphics card you have in After Effects? or does it rely mainly on ram and CPU power.

Thanks Bob

Adobe's making noises on its web site that a hot graphics card will be a BIG help for a future version of Premiere. But for AE, nah. Fast processors and lots 'o RAM are the big deal.

Sorry about your RAM limitation. It's like having a bowling ball chained to your foot.

Yes the 8GB limitation is not so bad; but as you mentioned After Effects loves ram and therefore the limitation is then magnified somewhat. Then again I didn't have After Effects back then when I built my computer.

Out of interest Dave, what spec do you run After Effects with?

I can't speak for Dave, but at the office my computer has dual quad-core Intel Xeon processors with 16 Gigs of RAM (I WANT MORE!!!) on Windows Vista 64 bit (to be upgraded at some point) and some sort of decent graphics card but since I'm just doing AE the card doesn't really matter a lot. I've got a zippy RAID setup too, btw.
(I also capture using AJA, but I don't think you were asking about that.)

At home I'm running a Pentium 4 processor (before they had hyperthreading) at 2.4 ghz, 1 GB of RAM on Windows XP service pack 2.
Yeah...
I need a new machine, but I plan to pay this off first.


Although, I do rag on my old machine occasionally, it still works. I did the intro for my friend's video with it and it didn't suck too badly. I mean, I expected it to die; the original is 1920x1080 HD
I mean, if the machine hadn't been so sluggish, I would have done more with the graphic, but whaddya want? It was free work!

I'm primarily a Mac guy. At work, I have a dual quad core Intel PowerMac running Leopard and AE8... and only 8 GB, too. So I know all about that ball 'n chain.

The home Windows machine? I don't even want to talk about it. Woefully inadequate.

I've got an eight-core Mac with 32 GB of RAM.

I'd estimate that for most of my HD renders, I usually have between 8 and 16 GB free, so that means I can leave other apps open and running. My large-raster widescreen renders nearly max out the RAM.

Well, more like annoyed with the doofus engineer who said, "You can't put any more than 8GB on these Macs."

He's the same guy who's the System Administrator. And the same guy who can't get our font issues sorted out... okay, the boss' machine is fine on fonts. Figures.

[Bob Crampton] "Wow 32GB of ram Walter, now I'm really envious."

When I ordered the system, the salesperson paused and said, "32 GB of RAM? Are you sure? What are you doing with this thing?" Adding the RAM doubled the cost of the workstation, but I work with some really large custom frame sizes, so I viewed it as an important investment to allow me to really use multiprocessing.

Like I said, for my HD projects, it's complete overkill, and 16 or 24 GB would have been enough.

For my large format work, though... like Michael said, when 64-bit AE CS5 comes out, I'll be upgrading RAM again.
