Corsair Vengeance LED in whatever color you want.
The main issue is you need a certain CL model of the TZRGB to run "reliably."
But the RGB ram also has a problem where if you look at it with ANY type of reading software (CPu-Z, HWINFO, HWMONITOR, ASUS Aura and G.Skill RGB) you can corrupt the profile of the ram that at best can disable the RGBs and at worst makes the ram unusable.
