Are you running AI Suite? I think latest version will update drivers for you - its on a tab.
If you running win 10, right click task bar
choose task manager
show more details
open performance tab
click CPU
right click the graph and choose change graph to
logical processors
this will show all your processors in small graphs. I only have 4 and most of time 2 of them aren't doing anything. But then PC isn't doing anything either and idling at .77ghz
On your motherboard install DVD you may have Asus CPU Z, it is a Asus labelled version of CPU Z which will show you more info about CPU. But then you need a DVD drive to use that.. i forget not everyone gets those these days. Seems an oversight on behalf of Motherboard makers, they need to release drivers on USB instead.
