So I have a Biostar TA890FXE mobo and just changing the multiplier I can get from 3.4 to 3.7ghz. With each step I tested it with 3d mark 11 and prime 95. Up to 3.7 I see increases in my 3D mark 11 score ( 4660 ish) If I step it up to 3.8 it stays at the same score and if I go to 3.9 it goes down to 4630 ish. But at 3.9ghz it will pass prime 95 test at 4.0ghz i get BSOD lol. So does that mean anything past 3.7ghz I will not see any gains? Or am I doing something wrong. I havent messed with the voltage because it was passing prime 95 up to 3.9 and if im going to see worse performance at 3.9 than 3.7 why bother or would adding more voltage even though it is showing stable in prime 95 increase performance?
