OverclockersClub published a review on the Patriot Viper 4 Blackout DDR4 3600 64GB Kit
A quote from the article:
This DDR4 3600 64GB kit is designed for those who need a lot of memory in only two slots. This encompasses any platform that is running dual channel. HEDT (High-End Desktop) CPUs like AMD Threadripper or Intel Skylake-X series use Quad-channel, which requires four DIMMs to operate at its full potential. This Patriot Blackout memory kit comes in two DIMMs and as such will fit perfectly into the mainstream ecosystem of current AMDs 3rd Gen Ryzen and Intel's 9th and 10th Generation CPUs. It is for those who demand a high amount of memory without sacrificing much in the way of performance. This memory kit represents the cross-section between practicality and efficiency.Patriot Viper 4 Blackout DDR4 3600 64GB Kit Review
