Hello, my cpu have one video card 7900 gt/gto of 256mb, 3 gb of ram and the Amd dual core 4800 of 2.41 ghz, my question is if you see the image below you will see the memory used when is rendering, appear 1308 mb,
ok if the render goes to 1500mb inmidiately crash, why if i have 3 gigas of ram this happens. how i need to reconfigure to avoid that.
sorry for my english

please help me with that.

Right, when it hits 1.5GB your total used by applications exceeds the maximum of 2GB that's the default in 32-bit Windows, and the result is that whatever app is making the request for more memory crashes because nobody writes a robust exception handler for that error.

What most people do is use the /3GB switch (Google it - it's too well documented to need explaining here) but this can lead to other problems, because what it does is to take Windows' 4GB memory map (the 32-bit Windows address space is 4GB independent of your having 3GB of RAM) and divide it as 3 for apps and 1 for system, instead of 2 and 2, which is the default. These numbers were set up when Windows went 32-bit way the heck back in the NT days, and nobody considered the situation of a computer with more than 1GB RAM, but that 1GB for system isn't all that much by today's standards and it's possible to overrun it and cause driver errors. If that happens, you can use the /USERVA=xxxx switch instead, where xxxx is the amount in megabytes to be allocated to apps. Mine is /USERVA=2700, because the full /3GB switch causes my video card driver not to load.

mmmm i see, yes we are going to buy a server with a lot of ram to avoid that, thank you very much for the info, in one or two months i will make a post with the specs of the server to know your opinion.
thanks
