About to order my components for a new system build, when I noticed that the voltages for the motherboard and RAM are different.

As you can see, the memory is rated at 1.8v (which I didn't think was possible for DDR3), whilst the motherboard specification says

"Supports four unbuffered DIMM of 1.5 Volt DDR3 800/1066/1333/1600* (OC) SDRAM, 16GB Max"

Does this matter? Will the RAM run at a lower voltage and thus be unstable, slower, or not run at all? Or will the motherboard be capible of supplying the required 1.8 volts?

the ram can run at 1.8v on that mobo, since it's amd not intel.

You will just need to manually set the timings and voltages in bios.

It will likely default to the JEDEC speeds of CL9 at 1333MHz with 1.5 volts when you first put it in.

Ah ok, so it will still run at 1.8V, I will just need to set it in the BIOS after I set up the system. Thanks
