Corsair XMS2 Voltages

[MouthBoy]

Hey All

I am running Corsair XMS2 2 x 2Gb. I cant find if my standard voltages are 1.8V, 1.9V or 2.1V. CPU-Z says 1.8V, but in the BIOS they show as 1.9V but some places on the internet say its 2.1V...

I have no idea

Can anyone shed any light? So you all know its the ones with the purple stickers and again CPU-Z says its 5-5-5-15.

Thanks

EDIT: Just to add something. I am currently testing at 904Mhz I think it is at 2V. Thats only +0.100V in the BIOS which leads me to believe its 1.9V default but that doesnt agree with anything on the internet.

Which kit though? PC2-6400, 8500?

8500 5-5-5-15 needs 2.1v.

6400 5-5-5-18 needs 1.9v.

its the PC6400. So 1.9V is stock? Is it ok me running 2.0V though? I am only running that voltage because I either run under 800mhz or over 800mhz at the moment. If I reach 3.6Ghz I will be running 1:1 ratio so might be able to put it down to 1.9V again.
