To fix some of the memory issues in Fiji, the following steps can be taken

Check Fiji Java version

Make sure you are running a 64bit version of Java

If you are not, then delete/rename the java folder in your fiji installation and download the 64-bit Java Development Kit (JDK)
Make sure that Fiji understands that you are running on this Java Version by setting the JAVA_HOME and PATH variables to the right location in Windows.

Increase The Allocated Memeory in Fiji

Go to Edit → Options → Memory & Threads

And set the memory to about 80% of your available RAM

Change ImageJ.cfg file

You can change the amount of RAM as per the instructions of the ImageJ wiki
