Is there any way to get this board to a higher FSB with a quad without insanely high VTT?

And what is this board doing on auto.

I cannot get thing remotely stable or even to POST at a high FSB unless i use most everything auto.

Here's what i just did.

Q9550 @ 7x477 (way below it's max OC)
1.4vcore
AUTO VTT (ET6 reads 1.5)
AUTO CPU reference (ET6 reads 0.76)
1.59pll
AUTO MCH everything (ET6 reads as 1.2)
AUTO MCH reference (ET6 reads as 0.76)

It runs P95 blend stable, & IBT 5 passes stable.

So i go into BIOS & change VTT to 1.5 manual + GTL to 0.76 (both values same as being reported AUTO), & the damn board cannot POST.

So wtf magic is AUTO doing?
I don't want to be pumping 1.5vtt into my chip...i only needed 1.34v on my P5Q-D.

I assume ET6 is reading things wrong...

Any ideas would be great.
