The RGB works very well with vibrant, bright colours and smooth transitions. Klevv memory isn't supported by any in-house RGB lighting software (at the time of writing), but If you want the modules to sync up with the rest of your lighting scheme, Asus Aura Sync, Gigabyte RGB Fusion 2.0, MSI Mystic Light Sync (this is what we used), and ASRock Polychrome Sync are all supported.
