Hi! Here's the problem I have. Any overclocking software works fine until I reboot. After that It does not. I set different clock for GPU core and memory but tests show 1000 mHz for GPU clock and 1500 for Memory clock under full load. Only setting that change is voltage. If I delete the driver and reinstall it, overclocking works fine again until reboot. Then moving the sliders doesn't change anything again. Tried it like over 10 times. Please help.
