Exact part number CT16G4XFD8266 — the uncommon Very Low Profile ECC unbuffered DIMM that short-chassis servers and blades demand (HPE DL20/ML30 Gen10, many 1U and NAS boards). Standard-height ECC UDIMMs will not fit where these do, which is why this exact P/N still sells for ~$90+ per stick new.
Matched set: same production week (2052), Micron 2Rx8 die (MTA18ADF2G72AZ)
16GB per stick × 4 = 64GB — maxes a 4-slot E-2200 board
DDR4-2666 (PC4-21300), ECC, unbuffered, 1.2V
Provenance
These were the working memory in my own HPE ProLiant DL20 Gen10 home lab server — its maxed-out config — pulled only because I consolidated onto newer hardware. Each stick ships in its original Crucial clamshell, padded, with tracking.
