ADATA's XPG Spectrix D40 was one of the company's first RGB DDR4 memory kits.  They were a little over the top and while they looked and performed well many people wanted a more subtle and sleek look.  Well today we have ADATA's XPG Spectrix D41 memory kit that gives users that sleek look, but still offers RGB lighting, and of course great performance.  The kit we are looking at today is the AX4U30008G16-DT41 kit which is a 16GB (2x8GB) kit running at DDR4-3000 speeds with timings of 16-18-18-36 at 1.35v.  This this is RGB kit you need for your next build?
