GTX 660 issue with idle usage and P8 P-state Two week ago i bought GTX660 and after that my problem started every 12-24h PC would just restart (No bsod at all just kernel power error) while being on idle doing nothing or just web surfing or even while the monitors were in standby... few days ago i found the restarts only happen when both monitors are connected at GTX660 (Samsung LCD over HDMI and Viewsonic VA2216w over DVI to analog adapter) I unplaged the analog monitor and no more restarts?? Also under load GPU is working fine tested with banch of games/demos also GPU temps are gr8 idle ~30C and load max 60C) So: 1. hw problem with bios or card 2. driver problem with low gpu clock and voltage 3. ??? 4. Kepler problematic ramdac with analog monitors Also i noticed the GTX660 has the same clock and voltage at idle with one or two monitor used Atm it is idling at: GPU 324Mhz at 0.887v Memory 162Mhz I have MSI GTX660 OC gpu 1033/1502 bios: 80.06.10.00.15 Windows 7 x64 306.23 driver I would like to know if anyone with 2/3 monitor setup with GTX660 can report desktop idle frequency/voltage?
