After effects multi core problem

I have an 8 core processors but After Effects only see's 4 cores.
I have an Asus P6T Deluxe mother board with the Intel core 920 i7 processor, 12 Gb of Ram and I am running vista 64. The graphics card is the new PNY NVidia FX1800 RT.
I tried to make adjustments in the memory and multiprocessor tab. I reduced the ram per core for 2Gb to 1Gb and turned off open GL preview.
Any suggestions?

the i7 range of processors is currently not supported, and there are known issues with the multiprocessing feature in a computer that has such processor(s).
A bug fix update will add support for these processors.
You may want to turn off multiprocessing until that update is released.

I am not allowed to say anything but "soon". Sorry.
With 12 GB of RAM (once the update ships), you may want to use 6 of your 8 cores (you can set the multiprocessing preferences to leave 2 CPUs free)... This should still give you screaming fast performance.

Sorry for multiple questions I asked earlier if this update will work with AE 7.0 and also wanted to know if AE 7.0 it isn't able to fully utilize the i7 can you tell me the which processor would yield the best render performance with AE 7.0?

It's hard to say how would AE 7.0 work on an i7 processor. Running software on hardware that didn't exist when the software was introduced is always a risky move.
It probably will work fine. But it won't take advantage of multiple cores, since AE 7 didn't have the "Render Multiple Frames Simultaneously" feature.
Rather than getting the best processor for AE 7.0 why not get CS4 which will take advantage fully of your i7-based machine?

Makes sense I have been looking at CS4 anyway.
In your opinion, is the i7 the way to go?
Right now my render times on my old P4 are way too long for the amount of work I have and I want to pick the best machine for the job. I am doing a lot of chroma key rendering and the i7 machine I am looking at is only $1000.

Yes, an i7-based machine should give you very nice performance.
To take advantage of multiprocessing, make sure you get at least 2 GB of RAM per core. So, in a quad core machine, you want at least 8GB of RAM. Otherwise, you will probably have to tell AE to use just two of the available cores.

Hi Adolfo,
i am running cs4 at the new dell t7500 with 2 Prozessors, and 12GB Ram.
But AE is incredibal slow. My Old Notebook M90 with Dual Core and 4 GB Ram is much, much faster.
To get out a 5 Minutes quicktime referenze (avid-dv codec) as a mpg, after effects need up of 30 minutes (without multiprozessing and using only 30% ram). If i enable multiprocessing the machine need up of one hour.
The same work, with the same harddrives (external) my notebook needs 5 minutes only.
I have tryed a lot (two weeks)settings in the presets (cache, multiproccing, ram) but without any access.
Good idea would be great - and helpful of corce ;).

Hi Adolfo,
I'm running into issues where it's showing incorrect system values.
This is what I run on:
OS: Windows 7 64bit
MB: DFI UTX58 T3eH8
CPU: Intel Core i7 975 Exteme @ 3.33GHz - (Overclocked to at one point @ 4.00GHz) I know I could go more but not at this time.
RAM: OCZ 12GB DD3-1600
GPU: NVIDIA GeForce 285 GTX 1GB
I have 12gigs installed and the prefs are only showing 8 installed.
Windows 7 shows I have 12gigs installed and so does CPU-Z.

Mind you that the latest updates have been applied to CS4.
Would the patch resolve the issue with the correct amount of ram installed?

Nubian:
As you can imagine, Windows 7 is not supported by the current release of After Effects. That's usually the case for any major OS upgrade that is released after the application itself.
I'd love to help, but honestly I don't have Win7 installed here and have my hands full helping people who are running supported OS/hardware configurations :)
