I have a SIMM G41 D3 Mobo with 775 socket which runs on 800 MHz default but is marked with 800/1066/1333 MHz , so I want to upgrade my bios, and the Mobo manufacturer has shut down the production(I think) coz nothing about the motherboard is mentioned on its website, so kindly help me by providing latest bios, or get me links where I can read about OC'ing the rig, thankyou.
