Powermac G5 2005 - max RAM 16GB on OSX Tiger 10.4

[joecool99]

I see that this system supports 16GB RAM max, however it's running OSX 10.4.11 Tiger (needs some older audio applications)

Would the 10.4 take advance of more then 4GB RAM ? Does the system needs to be 64-bit to address more then 4GB RAM?

Tiger will be able to use all the ram.

Tiger can address the ram, but one single application running on Tiger will not address it effectively. We did not start to see 64 bit rewrites until Snow Leopard, nor were they really supported until then. A few applications like those from Adobe used virtual memory buffering as in basically caching to ram rather than immediately paging to the disk. You may wish to research what was typical for the application in question.

I hated the G5s. I've never seen a line of machines with so many logic board failures. Not all of this was on IBM.
