My ioa/d and sa voltages are currently at 1.200, pch at 1.171. Ring voltage on my board is known as cache voltage. Asus lable this and vrin differently, vrin is known as cpu input on their boards. At 4.5ghz on 1.275 vcore, (1.2800 at load) temps can hit the low 70's on this chip in games, bit of a hot un here.
