I think the demand is also just incredibly low. Overclocking is already a niche thing, but adding the idea of binning into it narrows it down much, much further

I think the demand is also just incredibly low. Overclocking is already a niche thing, but adding the idea of binning into it narrows it down much, much further. You have two options, one is you buy a bunch of CPUs yourself, find the best one, then sell the rest (likely at a loss), or two you pay a premium for a performance gain that is not noticable in every day tasks. Combine that with how Ryzen performance scales right now, the FCLK, or memory clock. Most people definitely don't find memory overclocking to be worth the trouble (plus it is insanely hard to do beyond what the Ryzen calculator tells you to do).
