error occurred during initialization of vm could not reserve enough space for object heap minecraft server

Question

I have 32G of ram on my desktop so I know the amount of ram isn't the issue but I keep getting the same error saying "error occurred during initialization of vm could not reserve enough space for object heap"

Maybe I'm not running 64bit java? How do I change that? My computer is 64bit.

java -Xmx3G -Xms2G -jar server.jar nogui pause

The error could indicate you are using 32 bit Java, which can allocate +/- 1500MB on Windows. — Mark Rotteveel, Sep 02 '19 at 06:41
Mark I started getting the error again and i was running at 1336. I thought that I made sure that I was running 64 bit. How would I check? — Brad Stephens, Sep 03 '19 at 17:12

Using -Xmx3G sets the maximum memory used by Java (and therefore Minecraft Server) to 3 GB.

To allow it to use more RAM (say, 5 GB), change the argument to -Xmx:

java -Xmx5G -Xms2G -jar server.jar nogui pause

java -Xmx5G -Xms2G -jar server.jar nogui Invalid maximum heap size: -Xmx5G The specified size exceeds the maximum representable size. Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit. – Brad Stephens Sep 01 '19 at 18:13
-Xms1336m -Xmx1336m made the server run again but i'd like to run with with more ram than that. I'm guessing that means I'm running with 32bit instead of 64bit but I don't know how to change that. – Brad Stephens Sep 01 '19 at 18:50
