The only way to decrease your OC is to "reset to defaults" using Arc Control. if I want to add 50mv to my card I type in 50 in the line for volts. The volt adjustment has you adjust by whole volts instead of millivolts - I.E. The tool works for my reference A750 with a couple of caveats. So take the Arc OC Tool for a spin if you’re looking for a no-nonsense Arc overclocking application and don’t fancy having more bloatware on your system - not that Intel’s drivers won’t install Arc Control, regardless. Instead, Arc OC Tool aims to provide a simple user interface with the essential options for overclocking.

Unlike Arc Control, the Arc OC Tool doesn’t come with all the eye candy or the fancy sliders. Given that warning, we didn’t want to poke around at voltage changes much, though we successfully locked up our PC by trying a 200 MHz and 0.01V voltage offset. The software isn’t using the right values if a 0.01mV change represents a 10mV change. If you’re not careful, it’s possible to set >2V as I demonstrated before.” “IMPORTANT! Be careful when setting the voltage! On my A380 I have to set 1.00000 for the default voltage, then 0.99999 for 10mV less and 1.00001 for 10mV more. Also, it’s worth noting the warning listed on the website:
