I have purchased new Zotac GTX 560 Ti AMP (950\1100) in SLI last month. The performance is very nice up to last week. I know that they are overclocked and overclocking 560's will make them burn up to the high temperature like fire. Actually the main problem is artifacts of all sorts in game. and then when they hit 105 degrees then they automatically stop working. I cannot understand the reason behind that. these two cards on an X58 MB with an i7 920 at stock speeds in an open case with 24 C ambient. I search for this type of problem in other PC but they 90 degrees at the very max and full load. But my system get 100c and above just with average-heavy 3d stuff. Thought I'm not running the system with full load. Can anyone give me some solution to fix this problem? please help me.
