CPU VCCIO and CPU System Agent Voltage: Both of these settings help when we overclock the DRAM frequency. In our testing we did not gain any performance above 1.25V, however values up to 1.4-1.45V are ok if you are using air cooling. Since we used X.M.P. profiles for our memory these voltages will be automatically set. VCCIN voltage: VCCIN is the voltage going to the chip itself, not to be confused with VCORE which is the voltage going to each individual core. By default this should be set to 1.8. You can set it to 1.9 for increased stability when overclocking, but it may result in higher CPU tempera- tures. AVX Offset: AVX Offset ranges from 1 to 5. When you set an AVX offset it will reduce the multiplier by 1-5 (whatever you set it to) when running AVX instruction sets. AVX offset is found under M.I.T -> Advanced Frequency Settings -> Advanced CPU Core Settings. 12
