GeIL (Golden Emperor International Ltd.) has delivered some RGB DDR4 memory called Evo X that has two distinct and separate modes of operation for the RGB lighting. The simple method is to power the GeIL DDR4 from a 9V/12V fan header and then select a lighting mode using the switches built in to the memory modules.
Alternatively, provided you have a compatible motherboard, you can use an RGB header that connects to Asus Aura, ASRock Aura, Gigabyte RGB Fusion or MSI Mystic Light Sync.
Any major computer upgrade generally requires a full software reinstall too. No so if you heed the advice in the guide to Upgrading a Motherboard without Reinstalling. PCSTATS Tips
