Witojcie. Quick shot because it does not know what it looks like. I would ask for a substantive answer. At this moment I have 2x4GB DDR3 Kingston Hyper X Fury 1600mhz CL9 with radiators for 1.65V XMP. I have the ability to add 2x4GB 1600mhz CL11 Hynixa, usually straight without radiators, I found in the work.
I didn't find the right solution from the Internet.
