Different Ram Voltages

[RaidrX]

I currently have 1 GB (2 x 512MB) of PC2-6400 DDR2 Corsair CM2X512A-6400 at 1.8V ram in my computer. I wanted to get another GB and was at Newegg and saw all the Corsair XMS2 ram was 1.9V or above and was just curious if the 1.9V would be harmful or make any difference if I ran it with my old 1.8V ram.

So basically if I ran my 2x512MB 1.8V with the 2x1GB 1.9V ram I plan on buying am I gonna be good to go? Any help would be great, thanks.

According to the Corsair website your CM2X512A-6400 is designed and tested to run at 2.1 volts. If it runs fine at 1.8 volts, it will certainly take the higher voltage.

Make sure your mother board can handle the voltage too. I'm pretty sure most motherboards can handle 2.1 volts, but it doesn't hurt to go to the manufacturer's website and check.

Generally, isn't the memory voltage set separately from the voltages of other parts?
