I got a second R9 270 today. The new one is running 1.188v and the old one is running 1.163v. Can't change voltage settings in Afterburner and the BIOSes are exactly the same. Why are they different?

It differs from chip to chip, there is nothing to worry about, some need more voltage others need less at stock

This is why you should not get an FX CPU for ANY scenario other than rendering on a budget http://linustechtips.com/main/topic/286142-fx-8350-r9-290-psu-requirements/?p=3892901 http://linustechtips.com/main/topic/266481-an-issue-with-people-bashing-the-fx-cpus/?p=3620861
