So, I have yet another question about ram after researching forums and websites with info. So I have a i7 6700k and it says that 2133MHz is the lowest safest clock speed for ddr4, I've seen people that with a OC get it to 3000MHz or even 3200MHz (with issues). I've been looking at some dominator ram at around 2400-2800MHz https://www.scan.co.uk/products/16gb-(4x4gb)-corsair-ddr4-dominator-platinum-pc4-21300-(2666)-non-ecc-unbuffered-cas-12-14-14-35-xmp , if I was to get this ram and run it as 2666MHz with CAS of 12 would I need to OC my cpu and how would I go about doing so, like what parts need to be OC, thanks
