Why Final Cut Pro only see 2.3GB RAM when I have 4 GB?

If I go to Final Cut Pro > System Settings > Memory and Cash tab, I have application memory set at 90% and it shows 2304MB. Even if I set it to 100% it says only 2560MB. What's wrong? I have 4GB installed and if I go to About this Mac it says 4GB. Why doesn't Final Cut Pro sees it?

 

Thanks.

All Mac OS X versions right now are 32-bit, which means at most you can only really access 3GB at at time memory wise. So the remaining 440MB when you have Final Cut Pro at 100% is for Leopard to run. The first Mac OS X version to handle more than 3GB (aka 64-bit) will be Snow Leopard.

FCpro is a 32bit app , even uses not all cores , no modern gpu acceleration as well ,

Yep, yet FC Studio2 ask for Video card with QE and OpenGL... so, why ask if not using them?

The 2560Mb maximum memory is due to Final Cut itself:

 

There is a page on apple site on this issue:

http://support.apple.com/kb/TA27734

 

Not everything in this note is correct (for instance, 10.5 is a 64 bits adressable OS not 32) but it explains why there is this limitation.

 

Unfortunately Final Cut Pro 7 is still written in Carbon (not Cocoa) meaning that it is still a 32-bit application, and thus cannot address more than 4 Gig of RAM.

 

I guess that we will have to wait two more years and the release of Final Cut Pro 8 to get a brand new Final Cut, fully 64 bits and multicore capable.

 

And Apple will probably show the new features as "awesome" while the correct term should be "at last"

Complete bollock5 isn't it!

 

FCP 7 comes out just before SL and it's STILL a 32bit app - sounds like a joke ..

 

what cost a fortune is used extensivley by the broardcast industry and goes: - render, render, render, render, crash - render, render, render, render, crash - render, render, render, render, crash - render, render, render, render, crash - render, render, render, render, crash - render, render, render, render, crash -!?
