I've tried 320.49 and the newer beta as well and still not working. 2 gtx460s that used to work on old platform. Z87-A MB. Any updates?
so, I had a single MSI GTX770 4GB and running on three monitors. I wanted to get another 770 for the longest time, but MSI hasn't had stock on them since Black Friday. I finally said the hell with it and picked up a Zotac GTX770 4GB card for SLI thinking my rig would kick ass. I get home, plugged it in, and for some reason it was running at 1/3 the speed of the single card. I thought something might have gotten messed up with the driver installation. I uninstalled and reinstalled the drivers, but still nothing. I reformatted my computer twice, still the same thing. I tried each card on it's own to see if they were working, no problems there. I started to think my power supply was not working right (Antec 850, but a few years old). I heard a clicking noise in my computer after a bit that sounded like it was coming from my power supply (I have SSDs, no HDDs, so it wasn't that). I went out and bought a new 850WATT power supply, still the same problem. I test them on one screen, SLI works great, really close to twice the speed. As soon as I enable all three, it's 1/3 the speed of a single card. Driver version 335.23, btw. I have noticed a few of you posted having 2600k or 2500k and that it worked fine for you. Any clue why I'm getting such poor speed with SLI and Surround together? What drivers were you guys using back then?
