After doing this, go back to the previous menu and look for DRAM Voltage. This will most likely display 'Auto', in which case, you need to change this to your specific value. This will most likely be 1.65v, 1.5v or maybe 1.35v for DDR3, but it may be different if you have low voltage RAM.The Reference Voltage, also called the VREFDQ, DRAM Ctrl Ref Voltage, DDR_VREF_CA_A, etc., sets the threshold for a voltage level to be considered a “0” or a “1.” DA: 72 PA: 73 MOZ Rank: 30 Dram vref voltage - btbhf.labdibellesi.it

In addition, when RESET is low all registers are reset, and all outputs except PTYERR1# are forced low. The LVCMOS RESET input must always be held at a valid logic high or low level. Internal Vref DQ DQ Training with MPR Per DRAM Addressability. DDR4 Compared to DDR3 8/22/2013 5 Spec Items DDR3 DDR4 Density / Speed 512Mbp~8Gb ... DDR3 utilizes on-die voltage pump to generate higher word line voltageMy voltage Max has never gone over 1.28V (according to CPUHD and HWINFO64) while playing games and generally using my computer at normal load and my temps are usually around the 30C range. My voltage normally is around the 1.26-1.27V range under normal conditions. VPP (VPPM) voltage - voltage that determines how reliably a DRAM row gets accessed. Limit: up to 2.7 V. Vref voltage - memory reference voltage; "Configures" both the CPU and the memory module with the voltage level that separates what is to be considered a "0" or a "1"; i.e., voltages found on the memory bus below MEMVREF are to be considered ...

Are there any sites where people post BIOS profiles for Gigabyte boards, for overclocking. I have a EX58-UD4P with a D0 920 and 6Gb OCZ 1600Mhz ram and was looking for somewhere that has settings to overclock to.
Variations in process, voltage, and temperature can alter the electrical characteristics of the output driver circuitry, resulting in deviations from the desired signaling levels. Additionally, variations in other system elements, such as trace impedance, reference voltage (Vref), and termination voltage (Vterm) can also impact signaling levels.
