I've had my i3-6100 BCLK overclocked on my MSI Z170A Sli Plus board for several months but have only now realized a discrepancy which may or may not be anything to worry about.
The issue lies in the clock speed which I have it set to and what it's being reported as.
Windows, 3DMark, Geekbench, Cinebench and I am sure others all report the speed at 3.7Ghz whereas the only program which acknowledges the correct speed is CPU-Z. The post screen will also show the correct BCLK of 111.1 (I lost the silicone lottery) and the BIOS itself will show the correct speed of 4111.
I assume BIOS > all when it comes to readings but I'm just making sure if this is normal or I've been misleading myself all this time.
