Not correct; Win9x and 2000/ME/XP have a hard limit of 2gb per application
(due to the limit of virtual address space; the upper two gigs is reserved
for the system). Whether or not 9x can physically handle that much RAM I
can't say - the info above is purely related to the technical limit that
the OS designers placed upon application memory partitioning.

Win2k advanced server allows 3gb per application (it reserves "only" one
gigabyte for the system).

This 2gb limit is kinda scary when you consider that we have already seen
at least one POV image that uses more than half of that ... for users of
consumer Microsoft OS's, once scenes start hitting 2gb, no amount of RAM
will help the problem (POV will just fail with a memory allocation error).

  Bill Gates 1981: "No application will ever need more than 640k of RAM".
  Sidekick:        "And besides, home users could never afford that much!"

  Bill Gates 1991: "No application will ever need more than 2gb of RAM".
  Sidekick       : "And besides, home users could never afford that much!"

sigh.

As long as Dell&Co continue selling Pentium 4 PC's with 128 Mb RAM there
is no danger. ;-)

I think you are quite right, even presuming that you can use full 4 Gb on
other OS's the limit will come at least within about the next two years.  

Let's hope that at that time there are cheap 64bit systems available.

And BTW:
No application will ever need more than 16 Million TeraByte of RAM

(Anyone who wants to know how much you would pay for that?)

Compaq actually sells a 1.533 GHz Athlon with 512 MB RAM for 1249 $ IIRC.
My own 3 months old system can handle only 1.5 GB RAM at maximum and I
wanted to take advantage of the low RAM prices.
But even with some tricks, Win98SE works only with 1 GB RAM. :-(

I hope my next scenes memory usage grows slower than in the past.

Just for reference, a thousand Terabytes would be an Exabyte.  I have
no idea what comes after that, though.

Are you sure about that?

According to my reference: 10^12=tera, 10^15=peta, 10^18=exa

Hmm ok, missed one.  Still no idea what comes after exa ;)

I guess that's the maximum of most current (Athlon) boards anyway, 3x512Mb
modules.

I think for Povray renders requiring much memory Windows (98) is not the
best system anyway.

  This is quite curious because, AFAIK, the hardware limit in intel processors
(and clones) is currently at 64 GB (of course you can only address 4 GB at
a time because pointers are 32 bits long, but the whole 64 GB memory can be
used with some hardware paging mechanism).

  On the other hand, we should not be so harsh about Windows in this specific
case. I have no idea what is the memory limit in Linux, but I wouldn't be
very surprise if it was 4 GB as well... If someone knows better, it would be
interesting to know.

As of when I last compiled the kernel (version 2.2.x), I could choose a
limit of 2 GB or 4 GB.
