If your system uses an x86 64bit Intel Xeon CPU built after 2009 or an AMD Opteron CPU built after 2010 it is most likely compatible. For details see Zing System Requirements Documentation. At least 7.5 GByte of RAM is recommended.
Zing can take easily advantage of more RAM with its pauseless Zing GC as it is not limited by long Full GC pauses which you might have seen when increasing the -Xmx with your current JVM in use. Up to 2 TByte RAM (2048 GByte) is supported by Zing.
