have been running a single XFX 6600GT for about 3-4 weeks fine. I decided to purchase another for SLI. I followed the manual and read the Nzone instructions which were straight foward and basically said the optins will just appear LOL. well there not both cards show in device manager and i have the latest board and card drivers.
board 6.39 driver
Cards Beta 71.84



i get to step four on the Nzone instructions and nothing happens i reboot and it does not say SLI enabled. (step four is where it should detect SLI and enable it) (http://www.nzone.com/object/nzone_sli_howto.html


p.s the card have the bridge and Nvidia task manager isnt coming up with sli option as if only 1 card was present

Ive tried All avialible Bios's F1 F4 and latest F6 and no luck.
