you can't

nForce based motherboards don't support it.

it is only supported on AGP Model 3.5+ and from what i've seen AGP 3.5 has more troubles then anything....

All Motherboards who have a Firewire 1394 controller on-board can cause a problem when using a digital camera connected with a firewire 1394 connector and your vid-card.
The video signal been asynchronous with some vid-cards and should have conflicts over the firewire 1394 connector.
Some of these conflicts can been solved by rewritten the register or installing new driver patches, besides new vid-cards has build in this option in to restore this Isochronous video standard.

Even my nforce 2 mobo did solve this problem...

wtf.

that has nothing to do with Isynchronous mode.

its an agp feature to speed up fast write transactions. and isn't supported on agp 3.0.
