Should I change my RAM voltage to 2.0v instead of 2.10v

[tweakboy]

Hi all thanks for reading this.

I used to use 2.20v for RAM @ 1112 when I had 4GB kit. But I added another 4GB and it wont let me do that speed or anything near that speed. Soo Im @ 926mhz. This RAM is supposedly 1066Mhz @ 2.1v

Soo that Ive gone down to 926mhz will 2.0v be enough to drive the ram or should I stick with 2.1v Im not worried about heat but I wouldnt mind it being a little cooler... Thanks you all in advance.. thanks..

After doing some reading it says recommended voltage for this RAM is 2.1v So I think I should stick with that. Thanks all
