    I never thought Kronos had a Sonnet - they are rare. At first I supposed to find somebody who made CPU swap and overclocked 7457 to 1.8 GHz. I found such guy, but he don't know exactly the VCore, because after several month with 1.8 GHz he lower frequency because of high fan noise ( i.e. not ideal cooling )
    If somebody has Sonnet, it will be fine, but probably he don't want to remove cooler and investigate settings.

    and after that 7447B/C rated frequency rises upto 1700 MHz, and frequency of 7457 stayed on 1267 MHz all the time.
