My BFG 680i motherboard has greyed out most overclock options in the bios (such as FSB, CPU and RAM speed) all that’s left is the CPU multiplier and a few other things. Ntune is unable to implement any changes that it makes (even those that are greyed out in the bios). There is a very quiet high pitch squeak (like a dog whistle) when I try to change the fsb memory clock mode and it also freezes at this point. I do not know if the motherboard is responsible, but I am unable to make any changes to the graphics card fan speed or clock speeds either. To my knowledge I am running the most recent version of the bios. When everything is set to default the same occurs. Here are some photos taken from various bios menus that should be useful:
These are all my components and setup:
BFG 680i motherboard

4x1gb Corsair Dominator CM2X1024-8888C4D
Inno3D Geforce 8800GTX 500w Xlico PSU
Zalman CNPS 9700 LED
4 regular sata HDD 2 DVD drives
1 front 12cm intake fan and 1 rear 12cm exhaust fan
WinXP SP3
change fsb memory clock mode to linked then you can adjust the fsb and oc plus read stickie on top of forum
When I try to change the settings from auto to manual (better known as linked, unlinked or auto) this is where I get to the screen that I can do nothing on as all option are grayed out and my RAM is seen as 800Mhz instead of 1066.
