You could try signalRGB, but no guarantee it will work. It typically requires motherboard support to get it working.
Is it possible to control the RGB color on some aftermarket RAM I purchased for the R10.  I installed some PNY XLR8 and it's working great.  Frequency is good as is the CL timing.  They light up, but just color cycle.  It's not a clear case, so we're just talking about leaking light coming out through the vent holes when it's dark.   PNY mentions several software controls for different major motherboard manufacturers, but since this is a proprietary Alienware motherboard, will any of those work or are there third party controls that work?  It doesn't show up in Alien CC.
