the black one is 1.5v and the white one is 1.35v. i was wondering if you can explain the difference to me. is one better than the other. i'm going to 2x4gig and i'll be getting z77 sabertooth and i5 3570k . i might do some overlocking in the future but i need low heatspreader because of my nocuta fan heatsink. if you have better memory in mind please let me know.thank you.
