This is my build: http://pcpartpicker.com/p/V9NPvK

If you scroll down to the compatibility notes on the bottom, it says that my ram operates at 1.65 volts and my CPU can only handle 1.5 volts and the ram will under clock itself.

What does this mean? what will this do? How can I stop it?

By answering you are really helping me a lot!

all this means is that the ram will not run at the advertised 2400mhz speed, but will rather underclock to a lower speed such as 2133. this will not affect performance as you have a dedicated gpu which uses its own ram. My ram runs at 1600mhz and I notice no difference from my older 2133 ram.

The ram will automatically under clock itself, what he was saying is that you can turn on XMP which will allow you to run it at its rated speed, which for most scenarios would not benefit you.

Now I understand.

I have one more question though: When I first build this computer, If I don't enable XMP The RAM will run at 1600 MHz. If I did enable XMP would it break something?

Also If the RAM runs at 1600 MHz, it will take less volts than if it was running at 2400 MHz. How do I know how many volts it would take when running at 1600 MHz? or will it run either above or below 1600 MHz so that it uses exactly 1.5 volts?

Thanks for the replys guys.

Intel specifications are 1.5 volts for 1033 - 2400 MHz RAM. Regardless, there are kits that have more aggressive clocks / timings and they use 1.65 v. As of now, I never heard of a problem when running 1.65 v sticks.

Believe the Pro defaults DRAM to 1333, for full 2400 will prob want to use XMP and depending on your CPU it may take a slight OC of the CPU to run 2400. As far as 1.65, it's perfectly safe and Intel even certifies DRAM at 1.65 (I myself will only use 1.6-1.65 on high performance sticks generally 2133 and up)
