Does DDR RAM Need 2.5v?

[TFM]

I was just looking in my mobo manual to see what the highest DDR Ram i could use was. I have a mobo that handles either SDRAM or DDR RAM depending on what you want to use. But you have to change jumper settings to go from one to the other. About a month ago, i made the jump from SDRAM to DDR RAM and changed the necessary jumper settings ... or so i thought. I just now ran across another one that says this:
Pin 1-2 (Short: 3V SDR) (Default)
Pin 1-2 (Open: 2.5V DDR)

I don't think i changed this jumper setting when i changed out the RAM, but the RAM is working fine. Am i killing the RAM by running too much voltage into it? Does it really matter?

Any help is appreciated,
Chris

3v is too high. DDR usually runs stable at 2.6-2.75 depending on the type.

Many Ocer's boost the DDR RAM past 3v's to get peak performance...Just change the RAM jumper back and it should work, then don't worry about it.

Thanks - just set it back to 2.5v
