The Guru of 3D published a review on the Corsair Vengeance RGB DDR4 Memory
A quote from the article:
Join us as we check out the all new RGB series Vengeance DDR4 memory from Corsair. Not only do these puppies look awesome, they are properly specced as well. We received a 4x8GB DDR4 3000MHz CAS 15 DRAM kit from Corsair, so that is 32Gb at your disposal for dual and even quad-channel memory configurations.Corsair Vengeance RGB DDR4 Memory Review @ Guru3D
