If you guys are still looking for the C1E option in the MSI P35 Bios here's a few pics to show you exactly where it should be............. At least this is where its at on my MSI P35 board..............

Main screen, go to the advanced bios features (second option)



Advanced bios features, go to CPU features (third from bottom).



CPU features when you first go into them.



Press F4 when you're in the CPU features menu and you should see the C1E option come up.




This is he way it works on my current MSI P35 board as well as my old MSI P6N board, it's a standard MSI option as far as I know................
