I recently overclocked my GPU by 10 mhz on the core,shader and memory but after an hour or so idle the clock goes to 405 on the memory. I tried overclocking by 1 mhz on stock clocks and it still goes back to 405. Ive tried reinstalling drivers, reformat and reinstall of afterburner nothing seems to fix it. Ive also set my computer to high performance mode in the power settings and in the nvidia control panel the only way it goes back to normal speeds is after a restart
