I've tried almost everything so far. I got a pair of evga geforce 6800 ultras recently and set everything up. Windows and regular applications, surfing, chat, etc work fine. But when i attempt to play graphic intensive games (UT 2004, hl2, etc), everything freezes. I've enabled SLI mode both in bios and in software, updated to the most recent nforce drivers along w/ beta graphics card drivers, updated game fix patches for individual games hoping that would work, and made sure each card had a separate power connector. The hardware itself is fine, but am i missing something here? driver, software, etc? please help.

It most likelly your monitor (YES !!!)

Nvidia driver does not support pure digital moniotrs like Apple Cinema, Plasmas, HDTV LCD and some viewsonics. Specially those with high resolution 1920x1200 or more.

Try a CRT monitor or a "dual" Monitor LCD with both analog or DVI connector and try the analog connector. If it's work you have found the big secret from NVIDIA, that they have deleted all post from their web site.

SLI DOES NOT WORK WITH PURE DIGITAL DISPLAYS !!!!

SOYLEN GREEN IS PEOPLE !!!

NVIDIA STIFF US !!

Hi:

I have the same trouble.

the Nvidia driver works different if you have a "analog connection - with the adapter" vs a DVI connection. Some tabs where turn "OFF" by Nvidia in the Nview DESKTOP MANAGER when you use the DVI connector and are not being supported until the release of the next set of drivers.

I have a Velocity Micro Raptor dual PCI-e with 6800 GT (2) and SLI "ON"

The machine will work fine if the monitor if I use an old dual monitor that has both DVI and "analog" connectors, even when connected to DVI.

If the monitor is pure digital, or one of the lattest model. The card will identify this and will use the Pure DVI driver subrutine. This has advance timming "off". As a result SLI only support high definition monitor at their native resolution (Apple Cine, HDTV -LCD, Plasma and some Viewsonic Monitors). Monitor with 1920x1200 or more. Changing to a lower resolution will turn the creen into garbaje. OUT OF SYNC.

Nvidia knows about this and have erase all connects in their SLI site. If you have a SLI and DVI monitor try turning SLI "OFF" in the driver (NVIDIA TAB) reboot and then try to turn it back "ON" you will not be able to. So be very careful. Then you will get the two monitor like is mentioned here. The only was to go back is using system restore.

Playing games in those pure digital monitors can not be done with actual driver for SLI, changing to a lower resolution (most games are 1024 or less) will result in a garbage screen. The ystem will work fine if SLI is turn "off" but the other card will be there for the ride.

The only solution is to use a LCD monitor with dual connectors (that has both connector "analog and digital" ) or a CRT

The idea of SLI was to run games at higher resolution but Nvidia put the system put before the drivers where ready.

NVIDIA has failed miserably with this release.....
