I am doing a new build and the hyperX RAM kits look really nice. They also come in white, and in black. I want to mix one 16gb white kit with a 16gb black kit to contribute to my white and black theme. However, the voltages are both 1.5 and I'm afraid mixing that would be problematic, as the max voltage on my 4790k is just over 1.5V. Is this going to work? Will mixing them add the voltages and result in a blue screen?
