Hello,
I am trying to run a hybrid of my HD6850 and GTS250 for the purpose of running physx. My HD6850 of course is my primary card and my GTS250 is my dedicated physx processor. So as I was trying to set this up I ran into a snag.
With my 6850 already installed as my primary card it seems that installing a second card, my nvidia gts 250, fails because the drivers wont install. It will go half way in the install but then my computer will just reboot and freeze at the start up logo. However, if i did it the other way around like having my GTS 250 as my primary and then installing my 6850..it works. But that's not what I want . Even if I only hook up my monitor to my 6850, my 6850 is just an extension to my GTS 250 and has no gpu activity. I have tried everything, clean install of windows, cleaning drivers, switching pci slots, swapping psu's.....nothing is working. I just don't understand why is that if my Nvidia card is my primary card I am able to install my AMD card with driver with out any problems but I can't do it vice-versa. Has Nvidia done something to prevent us from doing this?
The procedure that I read from another says that in order for this to work you must
1) have already installed your amd card with driver
2) then install nvidia card with driver 256 and reboot
3) install physx software and reboot
4) install mod 1.05ff and reboot
5) test with star tails benchmark and confirm with gpu z
I can't even get past step 2.
Oh here is my system:
AMD Phenom II X4 955
Gigabyte 790XTA-UD4
8 gigs DDR3
Corsair 650 watt psu
Windows 7 64bit
AMD HD6850 cat 12.8
Nvidia GTS 250 (has two 6 pin power ports)
Thanks
