THIS KIT IS SINGLE RANKED ON CPU-Z. Just make sure you are aware!!
No problem going to 3600MHz using the XMP profile. Also got to 3800MHz manually tuned but I haven't had time to turn down the timing. But very happy with the set given the price.
I am on 5600X and using ITX, so the single-ranked-ness kinda suck, but the performance difference is so minor that the price completely justifies it (Was on discount for $129).
