32GB DDR5 6400 kit for AMD EXPO

This Patriot Viper Venom kit delivers 32GB (2 x 16GB) of DDR5 6400 memory with CL38 timing and 1.40V operation. The aluminium heat spreader in matte black carries a red Viper logo and silver name plate. AMD EXPO profiles are supported for one-click overclocking on compatible platforms.

AMD Ryzen 600 and 800 series builders

The modules are tested for AMD 600 Series and AMD 800 Series chipsets and carry EXPO certification, so they suit new Ryzen desktop builds that can use the 6400 speed bin. Systems locked to lower JEDEC speeds or Intel-only boards will not gain the rated frequency and should consider standard DDR5 kits instead.

Check motherboard EXPO support and 1.40V headroom

Before ordering, verify that your motherboard lists EXPO support for DDR5 6400 and can supply 1.40V to the memory slots. Confirm the board has four 288-pin slots if you plan to expand beyond the two modules supplied. Ensure the CPU memory controller is rated for the 6400 data rate.
