So far my 9900KS is my typical luck in binning..
My 9900K (July 2019) wouldnt be stable in DCS world at 4.7 All core unless I pumped 1.3 VROUT at turbo LLC. I knew it wasnt my board or RAM becasue a friend's silicon lottery chip from January 2019 was easy 5ghz at 1.25 VROUT.
My 9900KS easily does the 5GHZ claim, but i'm only stable at 1.298v VROUT when blender or realbench are running. Also Turbo LLC.
Maybe I always have bad luck, my 2500K, 4670K, 4790K, 9900K and 9900KS all were 200-400mhz off of what websites and reviews claimed was "easy" to do. Not even off of the "best" benchmarks.
I think the best bin I ever had was 50th percentile.
