I want to see his reaction when those 5.2Ghz 9900ks pop up in benchmarks! HehAre you suggesting the 9900K should ONLY be run with DDR4-2666 because that is the 'official' spec? Who buys a $500 CPU to gimp it with slow memory, especially since DDR4-3200 isn't really that much more expensive these days? You're literally paying $10 - $20 more for a 3200 kit instead of 2666, for a ~10% increase in performance on a $500 CPU, thats a no brainer. So Im not really buying that argument. If anything, I would think that most 9900K owners (and 3900X as well) would be running high end RAM kits with 3600 or even 4000 speeds. If you're gonna go high end you go high end with ALL components, not super expensive CPU with dirt cheap RAM.
I really don't understand the double standards. AMD can push their chips to the hilt (which is okay) but exploiting the free headroom baked into Intel chips is sacrilegious /s. I am reminded of that popular remark: "Ryzen loves fast ram." If there ever was a compelling reason to run benchmarks @3466 speeds on Ryzen systems, this is the one! LOL
