EXS 24 Logic Sampler Users Group

Hi all,
I'm getting ready to buy a new Dual G5 to run VSL on the EXS24.  How 
much of the 8GB that the box can hold can Logic access for the EXS.  
I've heard that it can only use 4 gig and there's no point in having 8. 
  Is this right?

Thanks a bunch

Apple's site says this about Tiger:
Tiger also provides access to as much physical memory as you can 
install in your PowerMac G5. Even 32-bit applications benefit from 
the system's ability to access large amounts of RAM: The system can 
manipulate data in multiple applications entirely in RAM for maximum 
performance.

Perhaps someone can confirm if Logic/EXS24 takes full advantage or not....

Thanks Colin,
that is very interesting.  The apple guru's at my local Apple Store 
seem to think that, even with Tiger, Logic can only access 2GB of 
ram....the maximum that 32 bit applications can access. hmmm.

thanks again,
julie

I can test this when I get home later this week on my 4GB system (I'm  
about to upgrade it to Tiger and Logic 7.1.)

Even if the app only uses 2 GB, it would still be useful to have 4  
which could be used for the OS, and other apps.  If that is a  
limitation, we could expect it would be a likely one to address in an  
upgrade.

If I were buying a system today, I'd get 2 x 256 SIMMS that come with  
it, and after a burn-in period, remove that memory and install 8 x  
1GB chips from crucial.com.

Multiple applications is the key.

It does not.

It's also a fantasy. :)

No, and Andrea from Redmatica explained this to me definitively,  
including links to the Apple site.

Each program in Panther and tiger can access 4GB of RAM. If you look  
at Activity Monitor with Logic (including EXS) loaded up to its  
breaking point, you'll find it gets up to 3.17GB or so (that's the  
max on my machine); the remainder of the 4GB is "overhead" and  
doesn't show up in that figure, but it's being used.

You can't work at that point - about 2.5GB is a practical maximum.  
That's still pretty good, because it's two Giga or Kontakt machines  
plus Logic, and you can run other programs in the rest of the RAM. I  
was able to run a Kontakt 2 outside Logic, but unfortunately the  
processor load was too high at that point (since I had two Space  
Designers open); I'm going to do some more fooling around to see  
whether that can be made to work. Whether installing more RAM would   
solve that (I have 5GB) is another question.

In any case, this is not 64-bit memory access. That's only for  
command-line programs at this point; the GUI hasn't been adapted for  
64-bit access yet.

Thanks everyone for the input....much appreciated.

thanks julie

Again: the practical limit for working is about 2.5GB, including  
Logic, as shown in Activity Monitor. Each program can access 4GB, but  
you won't get readings of 4GB in A.M.; the max reading before  
crashing was 3.17GB for me.

Since we've been discussing this lately:

The demos sound okay, not great.
