I'm using a A7V with a Tbird 800 @ 1000. My current setting is 100x10. So does that mean i'm only running a FSB of 100mhz. Theoretically, should I be able to run 133x7.5 using my regualar PC133? Would it make a difference in performance??

Theoretically, yes, you should be able to run at 133x7.5. Performance can change depending on what your doing (games, etc.) Only way to really tell is change the fsb rate and multiplier and run the benchmarks. I'm assuming you have rated pc133 sticks, etc...

Yup, some generic PC133. On my way to getting a stick of Infineon though that reportedly will do 145mhz.

A7V will NOT do 133MHz FSB due to the limitation of the KT133 chipset

It will only run your Memory at 133, but the BUS is kept to 100MHz DDR

Theoretically it can do the 133MHz FSB, and if you managed to get it to work at 7.5 x 133 it would be significantly faster then 10x100.

BUT the A7V is based on the KT133 chipset which is a notoriously poor overclocker via FSB manipulation. Very seldom to KT133 boardss work beyond 110MHz FSB.
You can however set the memory to run asynchronously to the FSB to push the memory speed to 133MHz.
