Corsair Vengeance LPX DDR4 3000MHz 16GB RAM Single Dim

I have two modules listed. Both are 16gb and 3000mhz. They work together at lower speeds e.g. <2666mhz but become unstable together above these speeds since they are from two different kits. one is Ver4.32 the other is ver5.2 if you want both i am happy to take offers. Note that the listed price is for one module.
