GeIL basically split the module into two PCBs, one more expensive, multi-layer PCB with the DDR4 memory and the other a fewer-layered PCB with the RGB LED lighting and independent power input. This is one of the first DRAM modules that doesn't use DIMM voltage to power the LED lighting, it connects to a USB 2.0 header and lets you control the color via a software tool.
They instead feature a tiny power input on the lighting PCB, which draws power from any vacant USB 2.0 header you may have on your motherboard (and also interfacing with your OS to let you configure the color.GeIL will offer the EVO-X in frequencies of up to DDR4-3866, and in densities of up to 8GB per module.
