Good day to everybody, sorry for my language,it`s not my native =) I have an issue with my y500, firstly I found the problem playing games, I noted that main graphics card is heating and working very good, but the second one 650M, is not very hot. I tried to made a test using Furmark, and the test showed that GPU load of second videocard is 0, however the first is loaded 99%, SLI is on, I can see both cards in device manager, total video memory is 4Gb, operating system is Windows 8.1 x64. Hope for your help.Thanks in advance.
