Patriot Memory’s Viper LED might not play to the RGB crowd, but its choice of red or white diffuser tops over monochromatic LEDs can still add flair to your system. More important, it’s a Viper product, designed for performance. The appearance may be good, but it’s still a secondary concern.

We said "choice," but the DDR4-3600 and DDR4-3200 versions only come in white. Builders who prefer DDR4-3000 or DDR4-2666 get the red version. The only crossover point between its red and white models is at DDR4-2400, which probably won’t interest a lot of enthusiasts.
