That's not great to hear, I ended up buying Corsair CMW32GX4M2D3600C18 though it's not in my hands as yet to try for another week or so as I bought online from the US and I'm on the other side of the planet.
I've been reading stories about folks not getting the ram to either run at full rated spec and/or RGB not working. And to think we all bought Corsair with the belief that it would be the most compatible for performance and lighting.
I've gone and got all Corsair fans/lighting, commander pro, H115 platinum, K70LP and dark core mouse etc hoping to keep it all working within the iCue ecosystem. I get a feeling I'm in for a heap of headaches and a lot of wasted money maybe, time will tell.
Edit: Well the good news is the ram I got just works, simple as that. I didn't do anything but it runs perfectly @ spec speed easily and the RGB flawlessly.
