I'm getting in on this thread late, and this may have been said already.
EXS24 uses Logic's RAM for handling samples. If you have up to the maximum
RAM Mac OS 9 can handle (1.5GB) and want Logic/EXS24 to access as much RAM
as it can, set your Preferred Size of memory to just over half a gig. Then,
it'll see and use what it needs. My preferred RAM for Logic in OS 9 is set
to 500427KB.

Remember that apps in OS 9 expand their RAM usage as needed. They'll start
below the preferred memory, and then expand as you load instruments. So,
maybe it's only using the 640MB because that's all you have loaded.

Another DUMB thing about "Mac OS Old" (versus Mac OS X) is that applications
can ONLY access your RAM CONTIGUOUSLY! So, if you load in Logic first and,
although it is set beyond 500MB in its preferred memory, it may only be
taking say 100MB and then you simply load in the Calculator, the Calculator
will BLOCK LOGIC from accessing further RAM. OS 9 deals with RAM in SOLID
chunks per app. Mac OS old cannot "jump" across the RAM used by the
Calculator to grant Logic access to more RAM BEYOND the Calculator. As a
matter of fact, when you boot Mac OS Old, it ALL gets loaded at ONE END of
the RAM. The apps start loading at THE OTHER END, one atop another.

So, always load your memory stable apps first (calculator, email app,
instant messenger etc.) and RAM hogs LAST (like Logic and Photoshop and web
browsers).
