I have an Aurora R8 (i9-9900k + RTX 2080 Ti).  All of my CPU bench marks are about 15% below the expected results (Cinebench r15 - only 1750).  I've set my OC profile to OC2, but the performance is still lacking. 

Did some research, and it seems like my CPU might be defective. Let me know what I can do. The machine was purchased less than 4 months ago.
