The biggest difference between working /3GB option and not working is
the memory card and its driver. It depends how much system memory it's
mapping. With the /3GB option, you're only leaving 1GB for kernel
address space and everything else. We've had to fit PCI-E graphics cards
to our Dell machines (which had onboard graphics previously) to get it
to work properly.
The nvidia cards seem to play nicely with the /3GB option.

Hello,
For me, I just put the /3GB option in boot.ini. Everything just works
fine.

Hello:
I am writing this email just for record.
I met the same problem as ZhiWei had in OCt 13,2009 while compiling
the tutorial example 4,'poco_wide_10_r311'.
http://www.mail-archive.com/[email protected]/msg00901.html
I followed the suggestion in the emails, put the /3GB option in
boot.ini. After rebooting, my Windows desktop didn't function as it
was, couple of strange error messages kept popping out and the
response is extremely slow. After i removed the /3GB option, it back
to normal. So, i am pretty sure the 3GB option made the malfunction
of Windows computer.
After searching the internet, i put USERVA = ???? with /3GB option.
At first attempt, i put "/3GB /USERVA = 2500" that means 2.5G user
memory. With the USERVA option, the Windows computer functioned well
as it should be, but i still got the "out of memory" error message
while compiling the wide band tutorial 4 example, 'poco_wide_10_r311'.
I also tried to increase USERVA =3030, the compilation of tut4 still
failed by "out of memory".
Then i put another option of PAE ,Physical Address Extension,as the
website below suggested as :
/PAE /3GB /USERVA = 3030
The compilation of 'poco_wide_10_r311' passed with computer time of
5:18:42. I compiled it again with computer time of 04:15:30.
