How do I underclock my RAM

[tigersty1e]

In CPU-Z, the voltage for my RAM reads 1.8 volts. But the default volts according to Newegg should be 2.1 volts. In my BIOS, the only options are Auto, +.1, +.2, +.3, +.4, etc. I have it set to Auto, so I don't know if CPU-Z is wrong and my ram is in fact already running at 2.1 volts. Is CPU-Z wrong or does my BIOS automatically select the default 2.1 volts?

It's rated at 2.1V, but when you set memory voltage to auto, it runs at JEDEC standards, which is 1.8V. If you want to run your memory at 2.1V, you'll have to set the memory voltage to +.3

Most BIOS will not run RAMs below 1.8V JEDEC standard. The slowest memory divider is 1:1.
