RAM and Nucleo Pro

[Kevin Camp]

i know i saw a post here just a week or two ago, asking a similar question about a pc workstation, but i can’t find it… the response back was that nucleo pro would use up to 3-4gb of ram for each processing core.

i think the mac may only be able to grab 3gb per core, but if you’ve read about ae and intel macs, you’ve probably heard about issuses with rosetta only allowing about 1.25gb of ram for non-universal apps (like ae). i’m not sure exactly how that may effect nucleo pro, but most people seem very happy with it.

you might look at gridiron’s site, or send them you’re question, although steve forde frequently answers questions here.

here’s a thread i found at gridiron, it’s about a 64bit windows machine, but they disucuss having at least 1gb, prefereably 2gb, of ram for each core. so at least 8gb could be used to render, the rest could be used for other apps and the os.

I received a response from the tech department at Gridiron. They say basically that Sys X has a 3GB limit per application. So, AE can theoretically address 3GB. I just asked whether there was 1.25 GB restriction for AE running under rosetta, so I haven’t heard back on
that yet.

Nucleo/Nucleo Pro creates six iterations of AE and its project when rendering – each needing up to 3GB as far as we know at this point – so the more RAM the merryier. They did tell me that testing showed that a minimum of 2GB/iteration seemed to work well. They weren’t sure just how much benefit the extra RAM would have other than for foreground work with Nucleo Pro, which allows you to work in AE while rendering or other applications.

good to know… i hope they respond to the rosetta question. i’ve been requesting nucleo since we got our mac pro.

have you read about some of the issues with ae7 and intel macs?

graham jones has a great article (and thread) here about better ae performance on a mac pro by limiting ram, although it seems if you have over 4gb ram there is less beneifit.

iv’e noticed some issues, particularly with older plugins… i get fequent crashes with some of them, including the cc effects that are bundled with ae pro. cycore does offer updated plugins for a price, but when i asked them about updates to the ones bundled with ae, they made it sound like they weren’t too interested in rewriting the freebies, although i hope they will for the next ae version. if you like cc effect it’s probably worth the upgrade. i’ve also noticed similar problems with many of the pete’s plugins, retrodots and sindots.

there’s another oddity with opengl and opengl accelerated effects. if you apply an accelerated effect (like gaussian blur or curves) directly on a layer, ae will crash immediately. apply them to an adjustment layer and they work great. other opengl accelerated features seem to work fine (motion blur, blending modes…), although antialiasing on 3d layers is rough (2d, ok… go figure).

I couldn’t get any sort of confirmation on the 1.25 GB limitation on AE running on Intel.
I appreciate the heads up on some of the Intel/AE issues.

Have you heard that Apple is releasing a new Intel machine – supposedly twice as fast at NAB?
