After Effects CS4 & 12gb RAM
Hi!
I`m just buying a new Core i7 editing machine, and wondering if there is need to buy 12 gb of ram. Can After effects use that much ram? Is 6 gb enough? I need to know because of motherboard... Thanks in advance |

on AE support page I found the following:
"After Effects on 64-bit Windows operating systems can use up to 4 GB of RAM with no special configuration for each After Effects process. In this form of multiprocessing, each background process renders its own frame and runs on a separate processor core (CPU). The number of processes used to render multiple frames simultaneously is never more than the number of processors" As I understand this you can assign max 4gb of memory to each core meaning 16gb of memory for a quadcore, but I guess you still need to leave some for your own OS to operate. |

This whitepaper covers the topic pretty well at least as a high level discussion of 64-bit performance. The particulars on After Effects are on pages 3 and 4.
http://www.adobe.com/products/creati...m_64bit_wp.pdf Note their tip at the end of page 4: "For After Effects, be sure you have the 9.0.1 update, and adjust the amount of memory per core for the Memory & Multiprocessing option under Preferences. After Effects will also instance itself, but it does this per CPU core, and each core can use 4GB." |
