problems with 8gb ram
Hi I’m running AE on a Q9300 Intel Core 2 Quad machine with 8GB of ram on vista x64, the problem is that AE sees only 4GB of ram instead of 8 :/
Can someone tell me what is the problem?? everything should be fine it’s a 64bit system -

your os is 64bit, but ae is only 32bit. being 32bit, the most ram it can address is 4gb.
however, with cs3’s multiprocessing (or nucleo pro), ae will launch a render engine for each processing core you have. each render engine can then be assigned 2gb of ram each. so if you have 8gb of ram and 4 cores, you can effectively use all 8gb of ram while rendering.
also, if you disable opengl for previews (preferences>previews), you can use ae’s multiprocessing for preview renders too (you can’t use opengl and ae’s multiprocessing together, they aren’t compatible).

I see, thanks.
So how should I configure memory & cache settings? sould i leave it as it is – 120% Maximum memory usage (4GB) and 50% Maximum RAM Cache size 50% (2GB) or configure it like each core should be using 2GB and set Maximum memory usage to 50% and Maximum RAM Cache to 25% ??? -
i’d go with something closer to the 120% max memory and 50% max ram cache. the ram cache is the portion of ram that will be given to each core.
