problem is with the PCIe frequency that in synchronous when FSB is raised.

Try to set it at Asynch Mode and set the value to around 115Mhz and you should be able to hit more FSB or better yet do the BSEL Mod.

Go to this thread for more info and help..

you have to do the bsel mod for a fsb 800 cpu to fsb 1066 cpu
then the strap of the northbridge is changed and in the bios it is set to
fsb auto 266mhz
pcie 100mhz
in sync mode

or u can take a look at ur mobo - when u see a area between the bios chip and the nb wich is called FD where are 3 contacts for a jumper.
but on this board there is no jumper for it so u have to cut this bridge and change it to pin 2-3 instead of 1-2 as default - that also will do the same thing with the strap for the nb
when u want to make it more professionel u can place there a 3 pin jumper - so u can always change between 800 original and 800 to 1066 strap.
i tryed that it works with a fsb 800 cpu only.

in this case u have the 115mhz pcie frequency if u reach the 333mhz fsb setting in the bios with a 800fsb cpu.

hope u understand bad english
