Ok I have decided to do a bios reset before I'm gonna remove the Kraken and put the Wraith on. So I've done that and re-ran the Cinebench R20 and IBT, and here are the results:
Not sure what I've activated ( and forgot about it ), but I know I've had might be Precision Boost Overdrive - Enhanced Mode 4. I was just sure that I've put it back as it was, apparently not. 25 degrees difference in OCCT. Woah.
So I can start to fiddle around now. Thanks for the help, everyone.
