the new drivers do not work!! can not detect sli mode (version 4 gold) although i have found a work round install v2000 drivers first glide version 256**** reboot install second card reboot then come back to
the update driver tab look for the version 4 gold folder where you unzipped to and update driver part way through the update you will find that the version 4 has older files just say NO to  the particular files you will find that the system 32 folder will have the glide 256 file now  go and copy the new glide file 1.000.00.0004 to overwrite whaller!  sli mode with new drivers.
