Error Code 43

[Demi]

Hi,

I bought another GTX 260 (216sp) today. Both cards are detected in the device manager , and in nvidia control panel. They are both connected properly to a new 750W PSU. Windows detected it and everything was fine. I restarted and I got error code 43. Device driver failed to load. Reinstalling the driver will allow the driver to work again, but then SLI cannot be enabled.

If I uninstall the driver, remove 1 of the cards, boot, power down and install the 2nd, I then can enable SLI, but only until the next reboot, after which I get error code 43 again.

Both cards works fine, I tested them. Could a newer BIOS fix the problem? Has anyone had this or heard of it? If anyone has any experience with this help would very much be appreciated.

Thanks!

I'm not sure if the 750w is enough for both card. Have you tried something more?

Which drivers are you using?

http://support.microsoft.com/kb/310123 , uninstall the drivers and reinstall it. code 43 means driver conflict i believe.

You have to use the 180.XX series nvidia drivers for sli to work with these cards. If you using windows xp then try this http://www.nvidia.com/object/winxp_182.08_whql.html , otherwise browse here :http://www.nvidia.com/Download/index.aspx?lang=en-us
