BUMP

I'm fairly new to iCue but have managed to get most things working right. I have an Asus x99-S and updated my ram to Vengeance RGB Pro 4x8GB. I have it in quad channel mode, in slot A1, B1, C1, D1. I had to enable SDP write in bios but iCue can only find 2 out of 4 stick. C1 and D1 are not detected but if I place all for slots in Dual Channel (A1, A2, B1, B2) all 4 sticks are detected and everything is good. Does anyone know how I can get it to all sticks to be found in Quad mode? and what would happen if I got another 4x8 kit and populated the other slots?
