Strange Vcore Behavior: Anyone have a Solution?

How come when I set my vcore to 1.250 in the BIOS, CPU-Z and other similar programs say the vcore is 1.272? It's the same for other values too - whatever I enter seems to be increased slightly. I have an i5 4690k with an MSI G45 gaming motherboard. Thanks.

EDIT: For example, I changed the core voltage to 1.275. I restarted the BIOS and go back into it and literally right next to the 1.275 I entered it says 1.288. WHY the heck is this happening? Shouldn't it read something the same as or similar to the value I enter??
 
Solution
Something I have noticed with newer generation motherboards is that if you are using adaptive voltage that they will essentially go with a predetermined minimum voltage for a particular clock speed. Also if you are using anything with AVX instructions that they will go as high as 0.1V over set voltage unless set on manual.
