AMD "Thuban" Core (Phenom II X6) XS Overclocking Charts

[mrbungle]

Just picked up a 1055T and a Crosshair iv and have hit a wall at 258mhz bus speed

Very stable at these settings but cannot get the board to boot over about 260, just bluescreens on login. Have dropped the multi and it still does it. I doubt its the IV, maybe a duff cpu? All voltages are auto though ive played with upping the ones to do with cpu and nb and nothing changes llc is enabled

Any help be welcome
