I should have specified when I posted before. I did mean on stock drivers and it may just be a Sager thing. If you download drivers from laptopvideo2go.com or the afore mentioned Omega's, you should be able to OC. With mine on stock drivers, I can unlock the OC portion using Coolbits and set it to what I want, but the settings automatically revert back to default. Some google/ forum searching may be required to find out if your system can OC with the stock drivers.
