When I run Cinebench R15, the core voltage fluctuates between 1.164v and 1.176v, which is below the stock voltage of 1.235v. My mobo is Gigabyte AB350-Gaming 3 and max temps are 51 C. Likewise, my CPU refuses to turbo to 3.6 Ghz and gets stuck at 3.4 Ghz. This results in an abnormally low Cinebench R15 score of 1060, which is a good 100 points below what others are getting. Why is this happening?
