Process in C#

Question

Hi friends, I want to know that What is the maximum amount of memory any single process on Windows can address?

Senthilkumar · Answer

Hi Amit, On 32-bit versions of Windows, a single process can map and address no more than 3GB of virtual memory at time. In 64-bit versions of Windows, a 32-bit process can map and address no more than 4GB of virtual memory at a time. For 64-bit processes, the amount is difficult to calculate as there are numerous overlapping limits that could apply depending on all kinds of factors. It's typically around 7TB. The maximum amount of virtual memory for the system is difficult to calculate and not a very meaningful number. Also, the limits on physical memory are not related to these limits on virtual memory. I suggest you to go through this official microsoft website for their memory limits for windows process. http://msdn.microsoft.com/en-us/library/windows/desktop/aa366778%28v=vs.85%29.aspx

Hi Amit, The maximum virtual memory for a 32-bit system is 4GB of which 2GB are available to the user processes (3GB running a special configuration). This affects system design when when designing for memory intensive applications such as databases, enterprise applications etc Thanks
