I am upgrading my PC and have gone for the i5 9600KF and I am looking for memory to go with it. I notice on the processor specs it lists DD4 2666MHz ram but I can find some DDR4 3200MHz for the same price as the 2600MHz. Am I better going for the 2666MHz or the 3200MHz, will the 3200MHz ram work with the i5 9600KF?
