6GB of DRAM? a 2GB and a 4GB stick? Try raising the DRAM voltage to 1.575

yes,adata 2gb 1333mhz stick and 4gb stick.the 4gb that im using has frequency of 1600,but my mob support only 1333mhz. does this has any thing to do with the lockup?

Try starting with the 2GB stick only and raise voltage as mentioned, save, exit and shutdown, then add second stick and give it a try
