mixing DDR2 ram of same speeds but different voltages?

[vexingv]

i currently have a 2x1gb kit of Corsair TWIN2X2048-6400C5DHX (5-5-5-18 @ 1.8V) on GA-EP35-DS3L. i was looking to get another 2x1gb kit, but there's a sale on a 2x2gb Corsair kit TWIN2X2048-6400C5DHX (5-5-5-18 @ 1.9V) for the same price after rebates. would i be able to use the two sets together even with the .1 V difference? i know that different speeds can be mixed and speed/latency will default to the lowest in the set. however, i'm not sure about voltage especially if some dimms require overvolting beyond the standard 1.8V to attain their rated speeds (ie. those that are 2.2V DDR2 dimms)

thanks

I wouldn't try it, you'll probably have problems.
