Hey guys, my Gigabyte GTX 560ti drops its frequency down to 405 core and 324 mem randomly during gameplay. The only way to bring it back up to 900 core 1000 mem is to restart the PC. The problem persists sometimes 1 min into games or up to 30 mins. I havent overclocked the card at all and I use MSI Afterburner to monitor clocks / temps. Temps never go above 55 deg celcius. Drivers are 266.66. Any advice would be greatly appreciated.
