  So how did you not catch that the memory you were looking at was using Hynix?
  
  I just had to look at the specs and I knew just by the Cas latency. There was no good memory in the DDR4 range that came in at CL18.

  Well, clearly, the site that I used thought it was B-die, when it was false info for the 2x16GB model.

  I remember when samsung released low quality "b" dies. It was in the news i think in tomshardware.
  These were used as "b dies" in corsair high end ram.
  And they were not as good as the top class high binned true b die.
  Someone correct me If I am wrong.

  The PCB the memory is mounted on matters too.

  micron m-die(?) 3600c16 working great on am4, it just wasnt available until a couple years after launch, samsung isnt the only choice
  
  and actually hynix had different dies, some tighter and more stable than others
  
  first hand anecdotal:
  
  1) in 2018 hynix cjr(?) 3200c16 / 2600x / msi b450m mortar = never fully stable, had to tweak low level ohms, maybe the cpu had issue, linux randomly showed amdgpu pcie timeouts in log
  
  2) though in 2023 the same hynix sticks work fine with 5600g / asrock deskmeet
  
  3) in 2020 micron 3600c16 / 3600x / asus tuf b450m = solid
  
  4) in 2023 different micron 3600c16 / 5600 with pbo / same msi b450m mortar from 2018, everything fine

  Before b-die memory I also had a G.Skill Trident set with Hynix ic:s (G.Skill 64GB (4 x 16GB) Trident Z, DDR4 3600MHz, CL17, 1.35V CL17-19-19-19).
  They also worked @3600 CL16-18-18-18 or 3733 CL17.

  I see unlike previous generations of Threadripper, AMD and its board partners are abandoning the "content creator/gamer" segment.
  
  Great for the workstation crowd, a loss for the aforementioned.

  The people who created Crysis could have used this. :-)

  and what does a content creator need tons of pcie lanes and quad+ channel memory for? regular desktop isnt weak with 16 high freq cores and 3d cache
  
  if workloads like rendering scale so well with cores then they also scale across multiple networked computers for a cost effective render farm instead of a single expensive threadripper
  
  main issue is probably the daw niche of extremely complex realtime audio synths/effects, but this has workarounds for years (prerender specific tracks), and it's not like we had better performance available in the past

  HEDT isn't back when the platform price of entry is more than double that of the top desktop setups. AMD did release Zen 4 TR cheaper than Intel's current closest equivalent ($1500 vs $2100), but when $1500 is the cheapest it gets CPU wise you could put together CPU/DRAM/mobo for less. This is why I've contended TR 3xxx actually marked the end of HEDT as that is when the price of entry became significantly higher than desktop.
