Lots of RAM
Fast hard drives
Your question is a little vague. What OS, Are you upgrading, buying or building?
I ditto Rick.
My extreme example
Lots of RAM (4GB per core)
Fast Hard Drives (2 drive RAID 0 w/ WD Velociraptors)
Lots of Cores (8, 16, 32!)
All the RAM in the world won't get past XP's 3.2GB limit. The RAM available to each process is divided by the number of cores. The more cores, the less RAM available per process thread. AE would be happy if it could have a terabyte of RAM, but it needs a new 64-bit or higher OS and needs to be rewritten for that OS. And while Adobe is at it, they could add XDCam support perhaps?
"All the RAM in the world won't get past XP's 3.2GB limit."
Are you saying Multiprocessing doesn't work in XP? I'm trying to follow what you're saying. You're making it sound like more than 3 gigs of RAM isn't useful on the OPs potential machine, which would surely be multi-core.
After Effects on current 64-bit operating systems can use 3.5-4GB of RAM per process, so it could make use of 14-16GB of RAM on a four-core machine.
quoting from the "Memory usage and storage" section of After Effects Help on the Web:
"The operating system imposes certain limits on the amount of memory that an application can use. After Effects on the Mac OS X operating system can use up to 3.5 GB of RAM, although only about 3GB is actually available to the foreground application, because Mac OS X uses approximately 500MB to load the user interface libraries. After Effects on 32-bit Windows operating systems can use up to 3 GB of RAM; however, to use more than 2 GB in After Effects, you must configure Windows XP or Windows Vista appropriately. (For details, see the Microsoft website or Jonas Hummelstrands website: www.adobe.com/go/learn_ae_jonaswindows3gb.) After Effects on 64-bit Windows operating systems can use up to 4 GB of RAM with no special configuration.
Note: These numbers are for each After Effects process. The background processes used to render multiple frames simultaneously can each use the amount of RAM mentioned above. (See "Render multiple frames simultaneously".)"
I recommend that everyone who is confused (or just interested) about RAM and multiprocessing in After Effects go and read that whole page, including the comments.
I know all of what you said (that's why I have 16GB), my point was that he made it sound like the original poster would not need more than 3.2GB of RAM. The guy is looking to build a new machine and I just wanted to make sure it's clear to him that at least for Multiprocessing in AE, the more the better.
"So After Effects can make use of 12GB of RAM in a four-core machine running 32-bit Windows XP."
Not true, since the 32bit OS can only see 4gig installed.
Oops. I believe David is right, and now I see that Mylenium may have been saying the same thing. Sorry to have muddied the waters. I've edited my post.
have built 32gb afx cs3 machines running xp64 and they crank :-)
afx will use up to 4gb ram PER CORE, thats why i specc'ed 32gb with an dual intel quad - afx cs2 doesnt multiprocess very well, so no need to go there
XP cant use more than 3.2 what ever your cores are
you are thinking about the 32bit version.
and that limit isn't exactly 3.2...
4GB is the amount of memory the OS can address
- amount of memory the OS needs to operate
- amount of memory your video card uses
= the amount left over for possible use by applications (after throwing the 3GB switch ect...)
The ultimate pc would be:
8 Gigs of ram
5TB HD space
a 2.8 GHZ Quad Core
SLI stacked 8800 GTX ultras
64 Bit vista or xp
uh yeah thats about it.
Since Open GL doesn't help in final render, seems like SLI is a waste...(unless you use the same machine for gaming as well...)
am I missing something here? I guess if you do a lot of long previews in your work it may help you a bit.
Me? I keep it turned off.
You should have two Quad Cores too :)
i have the same issue too!
I'm on XP x64 sp2
board asus p5w dh deluxe Intel 975x
Intel core 2 extreme QX 6700 2.66Ghz (quad)
8 gb ram
my system says that there are 8gb of ram available but AE Cs3 when starts says 4GB
Also tested in photoshop:
in performance tab / memory usage / let Photoshop Use :....maximum vailable is 3255 !!!
pls is there any solution on this?
AE CS3 is a 32-bit app, as is Photoshop CS3.
32-bit apps can only access a maximum of 4 gb/process on a 64-bit OS.
They can only access 2GB/process on a 32-bit OS (unless you enable the /3GB switch).
so i have 4 more gb useless!!!
what about nucleo? i heard that this plugin works better with a lot of ram.
Will this plugin use the extra 4 gb instead of AE ?
CS3 (or Nucleo) will use up to 4 gig per process on 64bit OS. AE multiprocessing opens multiple processes of AE. So, it can utilize your additional 4gb with another process helping you render.
ie. Enable Multiprocessing in Preferences. Render something and fire up Task Manager. Take a look at processes and performance.
you mean that more than 4gb is under usage only while rendering,
but what about when something is building in a composition?
for example , i m workinig on a 10000 x 4000 pixels vanishing point project that needs to be in a HD frame resolution at the end.
And i cant scaled it down, because i need a flying camera starting from a wide open view to a close up ....
