so i have told the bios to enable all cores ands also in msconfig/boot etc. but i cant work out why cpu-z says i only have 4 cores and wonder if its affecting performance. i have booted up a game and run stress test at the same time and the cores/threads dont change. i have my cpu set to core usage atm so wondered if more cores might pop up under load but that doesnt seem to show in cpu-z. cheers
