There is this strange problem that I am experiencing. I have saved a stable bios of 970/1048 with the default voltage setting. But, when I want to change it to 1.375 or 1.4V vcore, the clock's claim to run at these in gputool and msiafterburner, but in sensors both are at the stock speeds but the sensor says the gpu voltage changed. now funny thing is i can change and apply the clocks gpu/mem to any setting and hit apply and this won't have any effect. also CCC overdrive does not work either, when i have edited the gpu voltage from stock. I would hope to get some help from this community.
