I have ordered every part of my PC except for one thing, the memory. Surprisingly, this has been the main part that I have been debating the most, and I have come to a conclusion that I want 8 gigabytes of 1866 mhz RAM. A problem is that I have ordered a Noctua NH D15 CPU cooler, which does not allow much clearance for the RAM. Many of the lower profile 1866 mhz options come in at a much higher price point than I am willing to spend, which is around $70. An option I have come across is Kingston Hyperx Fury Black RAM, but this has a CAS 10 rating. I have heard that this RAM automatically clocks itself to CAS 9, but I am not sure if this is true. If anyone could confirm that this RAM clocks itself to CAS 9 or has any other recommendations, please feel free to answer. Thank you so much!!
