Can get above 4 GBs

[Aharon Rabinowitz]

wait – are you on a 64 Bit OS or not?

Because natively, AE will not see all 4 GB on a 32-Bit OS. However, it will use the extra RAM during RAM previews and renders if you enable multi-processing, because it basically opens up invisible instances of AE in the BG, and those instances will use the extra RAM.

Yes I’m running Vista Ultimate (64 bit) OS.

Can you be more specific ?
Wich motherboard do you have?
How much Ram does your bios show?
How much Ram does Vista Show? (system properties)
How much Ram does AE show ?

my cpu is athlon X2 4800 dual
motherboard is a ecs n-force 6
bios shows 8+ GBs
windows vista ultimate 64-bit shows 8 GBs
ae is limited to 4 GBs as advertise, no more
video cards is geforce 8400 gs 256mb pci-express*16

I just built it to get 8 GBs for faster rendering, I want to do this without going to Mac (no offense). If it not possible,
I would care to much for the extra 4 GBs.

Well it is the same thing in OSX; AfterEffects internally can only use 3GB. Under the multiprocessing tab you can enable to render multiple frames which will use 400MB per instance and then each instance can use all available RAM for previews.

I noticed a huge increase in RAM preview length when I went from 4GB to 6GB.

Switching to XP64 or OSX won’t help,
AE will use 4GB max, every renderinstance can use whatever is available (max 4gb).
So when using multiprocessor rendering, your system will use all the memory it needs.
