It sounds like RAM training issues. See if it still does it with EXPO disabled. If it doesn't then you can try using a lower RAM frequency by enabling EXPO then setting the manual setting one lower than it selects automatically. 5600 instead of say 6000 for example and see if that helps. -------------
