on the memory i only do mild overclocks so say 4.3 or 4.4 on a 6600k now with that can i OC the memory seperatly or does it scale with the cpu clock? can i get ddr4 2800 or ddr4 2666
I'd say 2666, no problem, and 2800 should be fine also, it will inpart depend on the MC in your individual 6600K, mine runs 16GB of 3200 at stock, others can't
