16GB DDR4-2666 ECC UDIMM for HP servers

This 16GB unbuffered DDR4-2666 module carries ECC and runs at 1.2V with CL15 timing. It targets administrators who need to expand memory in compatible HP systems without paying OEM list prices.

Major-brand chips in a standard UDIMM form factor

The stick uses Samsung, SK Hynix or Micron components and matches the HP 879507-B21 part number pin-for-pin. Installation follows normal UDIMM procedure; the unregistered design means it fits any slot that accepts a standard DDR4 ECC UDIMM.

16GB capacity at DDR4-2666 with ECC

The single decisive figure is the 16GB density at PC4-21300 speed with error correction. Buyers who need registered DIMMs, higher frequencies or non-ECC memory should look elsewhere.
