Hi ive bought some new ram corsair Vengeance LP 8GB CML8GX3M2A1866C9R and they seem to be running at 1333HMZ instead of the 1866MHZ they are meant to be capable of. I have a foxconn A55mx mother board and a AMD A8 3870K both of which claim to support 1866mhz memory so I am somewhat confused also I don't seem to have any option in my bios in which to manually set it :S any help would be appreciated thanks
