I am currently running Solaris 2.6 on a Ultra 450 w/ 400 MHz Ultra
Sparc chips. The current max memory a process can access it 3.75 GB.
If I upgrade to Solaris 7 and switch to 64 bit mode what is the max
memory a process can then access? (Looking at past posts it is implied
that it is over 4GB, but would like to get that confirmed and confirm
the actual number).
Massive Thanks,
Monty

Yes, it's over 4GB. For 32 bit processes the limit is raised to 3.996 GB; for
64 bit processes the limit is probably in the order of 2^44 (the amount
of memory addressable by an UltraSPARC-I/II mmu)
That's 2^14 (16384) GB.

can't tell 'ya. it'll be something like:
RAM + swap - (some amount for the OS, and other req'd functions)
on a 450 you may be limited to 40 terabytes--but if
you have 40000 GB of swap--welll....

The memory limitation of a processor is based on the external memory
interface. The limiting factor in any computer, however, is what the
motherboard can support, and your best bet there is to consult the
manufacturer's spec.
I assume you are talking about the Sun Enterprise 450. The specifications
on Sun's web site indicate a 4Mb limitation.
