Calathea Posted October 3, 2014 Share Posted October 3, 2014 Hi guys. I've gotten kind of tired of 2d benching and are trying to make use of around 20 graphics cards I've collected in recent years. I started with 3 way SLI on GTX 260 - man these cards are dirt cheap now, even got one for free Trouble is, even with 2-way, my fps is barely increasing! At the start of the test I get good fps, then it drops like crazy in a fews seconds to almost-single-card level. Wth?? Platform is X79 Sabertooth, 4960x,4x4 dom platinum... 1000W psu in good condition. Tried driver 296.10 and the newest possible, same stuff. Tried 2 different bridges, nuthin. Load is good, both cards are loaded 80-100% during bench. Mostly tried 3dm06 but also vantage. Quote Link to comment Share on other sites More sharing options...

Calathea Posted October 3, 2014 Author Share Posted October 3, 2014 I'm a real SLI noob, believe it or not. I don't know 100% what you mean, but will take a look when I get home. Quote Link to comment Share on other sites More sharing options...
der8auer Posted October 3, 2014 Share Posted October 3, 2014 Maybe he is talking about the rendering mode. Such as AF1, AF2 Quote Link to comment Share on other sites More sharing options...
K404 Posted October 3, 2014 Share Posted October 3, 2014 In the nV panel, there are different ways for SLI to operate and they DO influence the score. I've not tried GT200 SLI, maybe the driver doesn't sit well with your mix of cards and the benchmark. Quote Link to comment Share on other sites More sharing options...
Calathea Posted October 4, 2014 Author Share Posted October 4, 2014 Think I solved it. Ram was unstable, I blame bios/board, old X79 not really made for 2666 MHz. Noticed when I got CRC errors during big unzips, that's no good Quote Link to comment Share on other sites More sharing options...
