Today, we are looking at Patriot Viper Steel 3600 MHz CL18 memory in a 64 GB set consisting of two 32 GB modules. At the beginning of 2019, we had an opportunity to check a higher-clocked kit from that series (4000 MHz), but the capacity was 2 x 8 GB. Patriot’s Viper Steel Series is offered at speeds ranging from 3000 MHz up to 4400 MHz, with XMP 2.0 support.
