I would not use more than 1.9Vish...most boards default to this so how are you going to stay at 1.85V evp anyway unless the board allows you to set lower like the dfi.

Remember the cas4 clocks are not supported, my dimms may be better than ones you buy..mileage varies.

The modules are the LV ones...go tot he OCZ forum and click the pic of the modules for the link
