ADDING RAM AND SPEED TO AFTER

[Kevin Camp]

if you want all 4 processors to work all the time for rendering and previews you will need version cs3 or nucleo pro (from gridiron software). if you have either of these, then you will also need additional ram to feed the processors… the recommended minimum is 1gb per processor.

i have cs3 and a 4-core mac with 4gb ram and to get all 4 processors to work, i actually need to lower the default ram cache in ae, otherwise i only have enough ram for 3 cores. however it is interesting that restricting the ram cache to add a processor didn’t speed things up any more. although there was a noticeable difference just enabling multiprocessing, about a 1.6x boost (note that some effects and features in ae are multiprocessor aware already, and enabling multiprocessing doesn’t improve those).

Thank you very much moldyboot.
I have the same machine as you (RAM , processors), but in windows.
I understand the prossesors thing, but I,m wondering why the after tells me that it use only a maximum of 2 Gb of RAM (PREFERENCES / MEMORY AND CACHE), its possible to increase that?. Otherwise I’m working with the same power of 1 year ago machine, It’s that correct?.
Thank you again, I will apreciate any advice about how to set my machine(or after).

2gb is the most a 32-bit os can address for any application (well.. i think you can find a boot init file to allow 3gb…).

but that 2gb restriction is for a single application. when you enable multiprocessing in ae3 (or using nucleo pro) it starts a render engine application for each processor (in your case up to 3 additional render applications), allowing you to use up to 8gb (2gb x 4 cores) of ram for ae rendering.
