MSI Eclipse Plus: Does nForce 200 Boost 3-Way SLI?

With 36 lanes of PCIe 2.0, 3-way SLI could be the X58 chipset’s biggest challenge. If that turns out to be true, is Nvidia’s nForce 200 controller hub, which multiplexes the platform's connectivity, a solution? We compare three configurations to find out. Read more

I used to run SLI for the longest time. When I started playing Age of Conan, the SLI setup would crash it constantly, so I disabled SLI and played with one card. I quit Conan, updated to the latest GPU drivers, then went to turn SLI back up. The option was not there. Checked the rest of the options, thinking maybe it was under a different/new name, nada.

Looked online, no one else seemed to have the problem, so I checked my device manager. Aha, one of the GPUs had an error. "Windows has stopped this device because it has reported problems. (Code 43)"

Tried reinstalling the drivers, no change. Ran Mark3D Vantage, and my score looked low enough that I'm only running 1 GPU, so its definately running only one card.

Then I got an idea. I disconnected one card (the primary one I'd been using for Conan) and plugged in the one that had been sitting there unused. Restarted the computer, immediately noticed the BIOS, loadup, and Vista all have vertical lines on the screen. Look kinda something like this:


-- - - - --- - -- - - - --- - -- - - - --- - -- - - - --- - -- - - - --- -
-- - - - --- - -- - - - --- - -- - - - --- - -- - - - --- - -- - - - --- -

-- - - - --- - -- - - - --- - -- - - - --- - -- - - - --- - -- - - - --- -

Depending on resolution, they are bigger at lower resolution, and smaller at higher resolution. Device manager shows the GPU there, detected, but the same error 43. While I'd like to think its just a device error, it doesn't explain why the lines would be there on the BIOS screen. I switched monitors, the lines are still there.

The temperatures on GPU are normal, and I'm typing this while the lines are on screen, so it doesn't seem unstable. I have no settings for the display, it appears I'm running on the backup standard VGA drivers right now. Ideas?

Have you checked your BIOS settings? Could you have at some time cleared your BIOS or changed settings, and forgot to reset eveything for 2 video cards? Did you remove the card that worked, and simply replaced it with the one in question and tried it in the same slot? That would pretty much tell you if the card it's self has problems.

The BIOS settings only asks about SLI-ready memory. Otherwise, the nForceware controls and modifies the settings by itself.

At first I just pulled out the lower (working) card and plugged in the top one, and it showed problems. After making this post, I shut down the computer, and switched the top card into the lower blue slot and the problems are persisting.

UPDATE: I called a friend over, tested his 8800 Ultra in my system (with the lower, working card), and everything is working as intended. There is no error 43, SLI is available from the nVidia control panel, and of course, there's no lines.

So clearly its time to ditch the 8800 Ultra and move towards a 280. Any ideas why a card would suddenly, expectantly go bad? Especially since it was just sitting there in the case unused?

Reply to SilNate

Bah, same problem. Looks like i need a new card then, I also have an 8800ultra, from looking round i have found a few other people that have had similar problems with all 8800 models, doesn't make much sence to me.

8800 GTS just croaked on me also...was in a game, bluescreened, system restarted with vertical lines down the left side of the screen (before the OS load). It's been a good card for 2 years...

Picking up a GeForce 260 GTX OC today...

When an electrical item is switched on there is a brief surge of power through it and this can, and will, finish off a weak component. It`s like lightbulbs, one could be working perfectly for years then one day you turn it on and-pop!
