JVM in 32-bit mode, the maximum heap size that can be allocated is 1280 MB. So, if you want to go beyond that, you need to invoke JVM in 64-mode. Frequently Asked Questions About the Java HotSpot VM -Xmx-Xms-Xmx. In theory, on a given computer system, the addressable memory is 2b bytes where b is bit of the processor architecture. (Although there is much more to it like PAE and stuff. ). So maximum physical memory in a 32 bit is: 232 4X(1024)X(1024)X(1024) Bytes 4096 MB 4 GB. Confusion starts here because you can not really set 4GB as maximum heap size for 32 bit JVM using -Xmx JVM heap options.I have seen couple of comments on my post 10 points on Java Heap Space regarding what is maximum heap space for Java or 32 bit JVM or 64 bit JVM and why Windows As Guidelines for Java Heap sizing the limit for Windows XP/2008/7 is 2 GB.Maximum Heap can be allocated for 32bit JVM is 232 4G, Again 4gb will be devided into 1 GB for VM to use for runtime classes.

java -Xms1G -Xmx2G MainClass. In the above line, we have set the minimum heap size to 1GB and maximum heap size to 2GB.Practically, you will get around 1.5GB in 32-bit Windows, 2.5GB on 32 bit Linux and slightly more on 32-bit Solaris system. So the exact maximum heap-size may vary between java-versions (maybe even between different computers), but according to Oracle. On most modern 32-bit Windows systems the maximum heap size will range from 1.4G to 1.6G. So for anything that needs Java Stack Size ThreadStackSize 1024 kilobytes (1M).

Theoretical limit for maximum heap size on 32 bit JVM is 4G. I observed even after having 100GB of physical memory, was not able to allocate 4GB to a java process on a 32-bit machine. This might be because of below reason. So if its 32-bit windows, the max size is about 1.5gb to 2gb since windows takes some in the middle and needs to be continuous. So shouldnt the 64- bit be a lot more? RecommendMaximum Java heap size of a 32-bit JVM on a 64- bit OS.
