P35C-DS3R Stuck at 267 fsb

Long and short of it I have the following:
Gigabyte P35C-DS3R
2 X 2 GB Patroit DDR2 6400 RAM
EVGA 8800GTS 320
Q6600 B3 Stepping w/ Extreme 120 cooler in an Antec P180 V2 Case
Corsair 620HX PSU

So I updated the bios to the F6 and all was dandy at 3.01 ghz with 5-5-5-15 timings 1.468 v on the cpu to include vdroop, and RAM at 2.0 volts. With the RAM divider Memory was at 804 and was Prime stable for 12 hours.

I have ran this system at this amount for a good 4 months now. It froze today and I tried a few things:

1 stick of RAM. RAM in different locations, etc. The weird thing is no matter what I set it to it always reboots to 267 fsb. I can adjust the multi no prob. But the fsb is IDENTICAL regardless of which way I go with it (i.e. I cannot under clock it either)

So guys, I am stumped. I tried the f4 bios, the f6 bios, and the new f7 bio as well. I get the same error. I rechecked all of my settings and even manually set the pci-e bus to 101 to implement the lock and reset to auto as well to insure it was not the culprite. Bottom line is, I had a sweet 3.0 ghz Quad that will only run stock now because the motherboard seems stuck at 267. If someone has any ideas what I can do it would be great. RAM is fine, volts on PSU are fine. The big thing for me is that it shows all of my settings in the bios as there but will not adjust in anyway shape or form up or down on the fsb. It is always 267.

Thanks for taking a read and let me know what you guys think.

After updating bios you did do the "reset to optimal settings" thing in the main menu (i think the button is f7). Not sure whether it makes a big difference, but gigabyte reccomend doing it after a BIOS flash.

Does your computer instantly reboot? The motherboard will reset itself to default clocks if it fails to boot properly. Like when i push my CPU too hard so it wont even post, it simply reboots back at defaults.

So... maybe try resetting back to defaults, rebooting, and then when overclocking make sure you arn't missing anything that may cause instability.
