The cpu did 4,5ghz prime with avx win7x64 around 1,14v, I made fast tests on xtu 1,2v 4,6ghz volts not minimized with bad air cooler and geekbench and GPUPI 4,8ghz 1,25-1,27v, all on Maximus VII Impact. You can check at my hwbotprofile. CPU is non delidded, because of this results with good water cooling or very good air cooler should be better (I use Xigmatek Loki for tests on Impact)
