This tweak works well with MAYA! Thanks!
Rendering a big (7MB) scene in Blender fills up the RAM over time.
The final result is blender closes!
WHY !!

SGI sells 64bit Linux servers with 2048 CPUs and support for 128 TeraByte RAM.
NASA just bought one of these for their use.

This shows that open source is used in large systems.

Is there a 64bits build of blender for Windows ?

Running the 32bits blender on XP64 is not better than on XP32 for me …

I really wish people would stop dropping that 640k quote. Its totally false. I haven't been an MS fan since DOS 6.22, but I at least like to get my facts strait.

and 5 seconds on google will find about a dozen more links like that.

Note: Although the /3GB switch adds 1GB of logical address space to the application it also takes 1GB away from the system to use for resources for that application. This includes the graphics driver which maps its resources into the upper range.
Graphics drivers (both nVidia and AMD) are known to blue-screen when they are unable to allocate address space, so if this starts happening to you revert the change.

This limitation is a Huge problem to me!
Orion Tear(one short animation that I'm making) has two 150000 poligons characters + a 150000 poligons scenario, so 1.5 Gb ram fly away at Space Sutle speed. nowdays I've learned ways to avoid passing the limit, but in early times it was a huge problem…

A Quantum leap for blender " OH boy"

>"8 Tb will be enough for anyone"
>yeah right… I'm just waiting for 128-bit operating systems… :P

Actually the logical limit for 64 bit should be about 16*10^18 (= 2^64) Bytes - that's 16 Exabytes. The 8 Tb limit is due to other reasons.

16 Exabytes should be enough for a while. 32bit has been with us for 20 years now - 64bit will be with us for still a while longer and I seriously doubt anyone of us will live to see the jump to 256bit. And of course, that far into the future, an entirely different kind of computer (think quantum) may disrupt this scheme anyway…
