XP64 bit & memory

[Richard Cole]

Dear group

At the risk of a pest... I have two different PC XP65 w/4 gig of memory.  I
have install the new java.  In the imagej.cfg file have point to that
(D:\Program Files\Java\jdk1.6.0_01\jre\bin\javaw.exe) version.  From ImageJ
help, there is 3500MB memory, but I get out-of-memory at 2500MB when trying
to load image stack??

Thanks in advance

RWC

Try adding the -XX:+AggressiveHeap option to the third line of
ImageJ.cfg. It will look something like this:

-Xmx3500m -XX:+AggressiveHeap -cp ij.jar ij.ImageJ

Thanks Wayne, I added this tip to the ImageJ documentation wiki's FAQ
entry about increasing available memory
(http://imagejdocu.tudor.lu/imagej-documentation-wiki/faq/how-do-i-increase-the-memory-in-imagej).
