ok, thanks for your mooching, i have enabled them and does seem better as i was having trouble sometimes in games getting booted to desktop but now seems ok? early days though, just thought that enabling them would cause some sort of loss to something else, oh well, i'll see how it goes, oh and i had recently flashed bios to latest 1014 don't know if options were there before but certainly are now, thanks again.
and your correct the mobo manual is very vauge, i guess alot are.
