What I want to know is that will there be a performance difference between two sticks of ram that have the same speeds (1600MHz), same Latency (9-9-9-24), same company (Corsair), but one is 1.5 Volts and the other is 1.35 Volts. Thanks for any answers!
Slight difference, but the motherboard may simply select the voltage for you. Try running both in auto. Lower voltage ram is designed for a few newer Intel chipset boards; some have reported problems trying to run it; If you mix the two, use 1.5 volts for the ram voltage setting if you have any issues.
