RAM voltage question

[Dave2600]

If I change the DDR2 voltage on my RAM in the BIOS, do I also need to change the A and B channel VReference voltages?

Which Gigabyte board we are talking about?

EP45-DS3R. My RAM is supposed to be 2.1V and my board had it running at 1.8V.

No, Ref voltages change Automatically to the correct %. All you need to change is Dram Voltages

Some Ref Voltage info for you because you asked about Ref voltage >>>>

CPU Termination (Vtt) Automatically changes the following if manually set >>>

CPU Reference Voltage (.63% of Default Vtt/1.20) .76 ET
CPU Reference2 Voltage (.67% of Default Vtt/1.20) .80 ET
MCH Reference Voltage (.63% of Default Vtt/1.20) .76 ET

DRAM Voltage Automatically changes the following if manually set >>>

MCH/DRAM Reference Voltage (.50% of Default Dram Voltage)
DRAM Termination Voltage (.50% of Default Dram Voltage)
Channel A Reference Voltage (.50% of Default Dram Voltage)
Channel B Reference Voltage (.50% of Default Dram Voltage)
