Question about CT8G4WFD8266 ram



I am trying to find details on what type of micron memory modules are used in Crucial CT8G4WFD8266 ECC udimms.  From searching though the Micron website, I can only conclude that these are MTA18ASF1G72AZ-2G6 based dimms, but have no way to confirm without first purchasing.  Specifically I would like to know if Crucial 8GB DDR4-2666 ECC UDIMM (CT8G4WFD8266) memory is using Micron A-die, B-die, or H-die.  For my specific use case and compatibiliy reasons, this information would greatly help me in my decision on whether or not to purchase Crucial 2666mhz ECC udimms, or if I should go with another manufacture ***Edited to remove Crucial competitor*** who clearly specificies.


I suspect they are Micron B-die, but would like to first confirm.


Any information I could be provided, would be greatly appreciated.
