Hi and welcome to the forum. I think that maybe you made a  typing error in your post. Did you mean 1066 for the memory speed?

No 1666

It could be due to the fact that the F11C is beta BIOS and although such releases are generally stable, sometimes things get missed prior to the final release.

If the tighter timings are essential to you, with your rather impressive Overclock, I would suggest that you revert to one of the earlier BIOS releases that will allow you to obtain them or wait until the final F11 BIOS version is released.
