Hi Guys,
Have been looking for DDR4 RAMs and found the below which seems quite cheap. These are 3600 Mhz, not sure if you will notice any real world differences vs 3200 Mhz.
Kingston Fury Beast RGB 32GB DDR4-3600 RAM
Youtube clip below provides a review (apparently these are just rebranded HyperX brand)
HyperX was acquired by HP. Kingston created the Fury gaming branding to replace it.
