I have a 4.3 OC on my i5-6600k and the voltage is set to 1.25
should I have it set to constant or adaptive
 
Solution
I would go for completely manual voltage. As the modern Intel chips have dynamic voltage scaling already built in, the adaptive settings really are not necessary (see this). What motherboard do you use? I do not know wether 'constant' voltage actually means manual or if it is a different setting on you specific motherboard.

Simply, I'd set voltage to manual, and then set it to 1.250 volts.

While overclocking go with a manual voltage. Turn off Turbo, SpeedStepping (EIST) and C-states (energy savers). Find the highest multiplier that is stable with the least voltage. Once you find this (your max OC), re-enable EIST and any c-states you wish.

You can leave the manual voltage set, or you could try using an adaptive or offset voltage (Vcore) but note this may a bit tricky to get working on the Gigabyte boards.

This thread has some info on my adventures to get adaptive voltage to work on the Gigabyte board: http://www.tomshardware.com/forum/id-2970985/safe-vcore-6600k-tips.html#19199313. ZEBuckeye81 and myself were able to get it to work but philipew wasn't able to get it to work. It can be a challenge and you need to find your max multiplier and manual voltage first.
