In my main system's mobo : Asus Striker II Formula, I had to DOWNGRADE my bios to make my Kingston DDR2 1066MHz mem sticks run at that speed. Otherwise, using a more contemporary bios versions, I couldn't increase the default 800MHz to 1066MHz without increasing the FSB at the same time (Linked overclocking). Increasing the FSB even within the workable stable range with all the necessary voltage adjustments, produced unexpected auto reboots while playing 3D games. (The unlinked option waz greyed out). After downgrading, I was able to increase the memory's speed to 1066MHz without increasing the FSB (Unlinked).
I downgraded several revisions back, I think from revision 2001 to 1201. I reflashed each revision backward from 2001 till 1201, after which the system is stable at mem speed 1067MHz ( shows as 1067 at P.O.S.T., in bios is 1066.666) and FSB 1333MHz. Current bios revision at asus website is 2201. I'm still using the 1201 revision without any problems.
I'll never know if the Kingston HyperX memory sticks or the intel Q9300 CPU and/or the combination of the nVidia 780i chipset with all these and the bios revision is causing the hiccup. But I managed to run the system smoothly now.
Not sure if this is related to your problem, but reading this thread reminded me of the problem I had as written above.
