60 Day 100% money back guarantee. Offered here is a matched Patriot Viper Steel desktop memory kit consisting of two 32GB DDR4 modules for 64GB total capacity. Both modules are labeled PVS464G320C6K and rated for DDR4-3200 / PC4-25600 operation at CL16 and 1.35V. The gunmetal aluminum heat spreaders appear clean and show only minimal handling wear in the supplied photographs. The seller described the set as like new; however, no functional or memory-diagnostic testing was performed, so performance is not being represented beyond the markings on the modules. This is a 288-pin desktop DIMM kit intended for compatible DDR4 motherboards. Please verify motherboard capacity, DDR4 support, voltage, and memory-profile compatibility before purchase. Included are the exact two matching memory modules shown in the photographs; no retail packaging or other accessories are included.
