Wrong AGP-speed on Asus CUSL-C

When I run The FSB/DRAM/PCI at 133/133/33 Sisoft Sandra reports that I am driving the AGP-port at 89 MHZ.
It seems that the system uses the 2/3 divider instead of 1/2.
Since I can´t change the divider manually I really need to know what to do to get the AGP back at the right speed (66 Mhz).
Also, as soon as I overclock the FSB over 133 Mhz the AGP changes from 4X to 2X, why?
I have a Asus v7700 GTS-card.

SISOFT Sandra reports all sorts of wrong information for the ASUS CUSL2 motherboard. Ignore it, as the motherboard is hardwired to use a 1/2 AGP divider at 133MHz FSB.

ASUS also drops AGP4X to AGP2X at FSBs above 140MHz. Supposedly they did this for stability reasons. In terms of real world performance, you will NOT lose a material amount of speed.
