For some reason the F5 final and F5h beta bios put my PCI-E x16 with my 8800 GTS in X1 mode whenever I overclock the CPU, returning to stock restores x16 mode. Anyone noticing this also?
I'm using F5 final on GA-P35-DS3P and don't experience this problem, both CPU-z and nVidia control panel show PCT-E at 16 (running eVGA 8800 GTS 320MB).
