My factory overclocked msi gtx 580 automatically underclock itself and I have no idea why. The core clock is supposed to be at 832mhz and I noticed on afterburner that it is now at 772mhz. What would make this happen. How could I fix this. Any help would be appreciated.
Sometimes after the driver fails; it doesn't re-register with your Operating System Key. After you've done those two steps; reboot your machine. Open up your game and it should be running at your factory clock you set.
If it is running at your factory clock; then close and start Overclocking again. As I said when that happens it's usually related to your Overclock causing a fail to your driver. Hope that helps; if you need any more assistance let me know.
