Hi everyone, I was hoping someone would be able to troubleshoot this problem of mine. I just bought a second GTX 260 216 for my system and am having problems with SLI. I've never dealt with SLI or CF before, so this experience was all new to me. I mostly guessed my way through it, so I think maybe I did something improperly? I'll describe what I did:
I installed the latest drivers, but in doing so ran into a few annoying problems. I think everything went fine in the end though. I first uninstalled the existing driver and rebooted. My plan was then to enter safe mode, delete out all the remaining crap with Driver Sweeper, reboot into normal mode and install the new driver. I'm running Vista 64 Ultimate and Vista was insistent on installing a default VGA driver after I rebooted the first time and I have still found no way to get it not to do that. After an online search I couldn't figure out how to make it stop, but I also read that it isn't a big deal and eventually gave in to the fact that I would have to install the nVidia driver with that default driver already installed. So, in the end, it went uninstall, new default vga installed, safe mode sweep, new driver installed.
I then put the card in, followed the mobo book on the slot to use (as if it would physically fit anywhere else), and powered back up. The screen blacked out a number of times after it got to the desktop. Windows installed the nVidia driver for the 2nd card by itself and prompted a reboot. I went along with it and when I got back to the desktop I was given a traybar warning about SLI. I followed along, turned on SLI in the nVidia control panel, and I assumed I had done things right.
Then I tested it out in the game I had been playing most recently (EQ2). It seemed significantly more jerky than before and I was sure I was getting a lower framerate, but thb I didn't know how to quantitatively check that in that game and I didn't try to figure it out just then. I instead did the benchmark in Far Cry 2 and it was ~25-30 FPS, which is what I was getting before, except it actually seemed more jerky somehow than previously with just 1 card installed. I was playing at max settings on 1900x1080 resolution. In doing a quick search I found this link: http://www.pcgameshardware.com...hmarks/Reviews/?page=3 with a benchmark for Far Cry 2 averaging 60FPS and dropping to 46 as a min with SLI GTX 260 216. That is about what I was expecting after the upgrade.
I'd love to hear that I did something blatantly wrong in the approach and that it's an easy fix!
Thanks.
