Multiprocessor problems
hi, i have 6gb of ram, and a quad processor, and in the options i cannot make after effects CS5 even use 2 processors… what am i doing wrong?
Settings:
Installed Ram 6gb
Ram reserved for other applications: 0GB
Ram available for After effects 6GB
Render multipole Frames: ON
Installed CPU: 4
CPU reserved for other applications: 0
Ram allocations: 0,75GB
Actual CPUS that will be used: 0then i get a message in the info panel saying: Insufficient RAM, Multiprocessing disabled.
What´s wrong?

more ram would be better, but i think you should be able to get mp running with 6gb and 4 cores… you might check out todd’s blog:
he lists configuration suggestions for 4 and 8gb.
i have 16gb ram and 16-cores (dual quad-cores with hyper threading), i’ve found leaving 6gb for other apps and 1gb per cpu seems to give me the best performance. despite ae saying it will use 8 cores, i can see it using all 16, so that info is a little misleading. when i increase ram per cpu, i can see less cpu activity (watch activity moniror or task manager to view cpu levels).
also, never set the ram to leave for other apps to less than the minimum necessary for your os… and honestly, if you want good performance you should leave a lot more than that, otherwise the os will start using disk caching which will really hurt performance.

From the research that I have done it seems that 2gb of ram per core is the sweet spot for a Mac Pro.
