Then, you’re not the target audience.

It doesn’t do nothing. FTA: “Their sole purpose is cosmetic, though. While they light up and synchronize with your existing RGB ecosystem, they don't contribute to your computer’s memory capacity or performance.”

This is for people with transparent PC cases and memory sticks with RGB LED lighting. For example, see https://v-color.net/collections/prism-pro-rgb-memory-voclor/...:

“RGB SOFTWARE SYNCHRONIZATION SUPPORT

Dynamic RGB lighting control synchronized across main leading M/B such as RGB FUSION, MSI Mystic Light Sync, AURA Sync, POLYCHROME Sync etc. Customize lighting profiles or assign colors to each LEDs to create your own spectacular look.“
