Corsair Vengeance RGB Pro DDR4 3600mhz

Selling my RAM as I am upgrading to a DDR5 setup and trying to offset costs. 2 x 8GB (2 sets). Memtest86 conducted with 8 test cycles and zero faults. I've overclocked the sticks before to 4000mhz with stable gaming/multitasking so chips must be a decent batch. 2 x 8GB = $180 4 x 8GB = $320
