Hey @chew* haven't had a chance to actually test 2x8GB yet, but it's on the chopping block tonight
I only have a 5950x so I can't comment on the lower core count cpu's but I imagine having more cache can only be a good thing just like Zen 2. CB is shit on the two samples I tried at any fclk.
@I.nfraR.ed it seems like it's way slower at both 4/5Ghz on this end. I can even train 2133/4266 but not stable. I'm not sure I know about this slow down, but simply running pi 1M you can see the difference, as well as checking with aida64 as all memory operations are slower at 2100 IF vs 203
