In all memory reviews, we remove the heat spreader to get a better look at the PCB and the memory modules any given company uses. Removing the heat spreader also allows us to see what brand the memory modules are. In the case of the Patriot Viper RGB memory, they used Samsung memory, model number K4A8G085WB-BCPB. https://www.samsung.com/semiconductor/dram/ddr4/K4A8G085WB-BCPB/ Each DIMM has 8, 1GB memory modules on the PCB. There is also a thermal pad running the length of the PCB covering the modules.
