I have a Intel DZ77BH-55K motherboard and I bought 8 Gb of this memory for it http://www.newegg.com/Product/Produc...82E16820145315 that runs at 1.35 volts. Now I want to add another 8 Gb of memory like this http://www.newegg.com/Product/Produ...47096&RandomID=420526616725020120121105225057. I'm not into overclocking or benchmarking so I don't care about that. My questiion is can I mix and match memory of different voltages?
