I am getting an Out Of Memory exception in my C# application when the memory usage for the application goes over about 1.3GB.
I had this same problem on a 32-bit machine with 3GB of memory and it made sense back then. But now I upgraded the hardware to a 64-bit machine with 16GB memory using a high-end motherboard and high-end RAM, but the Out Of Memory exception still occurs after 1.3GB!
I know that there are no single objects over 2GB and 1.3 is less than 2GB anyway, so the built-in MS 2GB limit on a single object is not likely to be the problem.
It seems like there is a Windows kill-switch of some sort when an app reaches a certain memory usage threshold. Then there should be a way to configure this. Is it in the registry perhaps?
Any help will be greatly appreciated!

There is no difference until you compile to same target architecture. I suppose you are compiling for
32
bit architecture in both cases.It's worth mentioning that
OutOfMemoryException
can also be raised if you get2GB
of memory allocated by a single collection in CLR (sayList<T>
) on both architectures32
and64
bit.To be able to benefit from memory goodness on
64
bit architecture, you have to compile your code targeting64
bit architecture. After that, naturally, your binary will run only on64
bit, but will benefit from possibility having more space available in RAM.
