Samsung M391A2K43BB1-CTDQ 16GB DDR4-2666 ECC UDIMM Server Memory

Samsung M391A2K43BB1-CTDQ 16GB DDR4-2666 (PC4-21300) 2Rx8 ECC Unbuffered UDIMM Server Memory (Certified Refurbished)

The Samsung M391A2K43BB1-CTDQ is a 16GB DDR4-2666 (PC4-21300) ECC Unbuffered memory module built for servers and workstations that require ECC data integrity in an unbuffered (UDIMM) form factor. With a 2Rx8 dual-rank design and on-module ECC error correction, it pairs reliability with the broad compatibility of standard ECC UDIMM platforms for file servers, edge nodes, and entry-level workstations.

Why buy from Byte Boost Memory: every module is received, bench-tested, and audited before it is certified refurbished. We record each module's serial number for warranty tracking and back it with a lifetime warranty, so you get enterprise reliability at a fraction of new-part pricing, with support that lasts the life of the part.

Compatibility: ECC Unbuffered server memory for systems that support 16GB DDR4-2666 ECC UDIMMs. ECC UDIMM is not interchangeable with Registered (RDIMM) or Load Reduced (LRDIMM) memory. This is server and workstation memory and is not compatible with systems that only accept non-ECC desktop memory.
