8GB DDR4 2666MHz Desktop Module

This 8GB DDR4 2666MHz DIMM is built as a direct replacement for Samsung modules M378A1K43BB2-CTD, M378A1K43CB2-CTD and M378A1K43DB2-CTD. It runs at the standard 1.20V and fits 288-pin desktop slots. The single 1Rx8 module is tested at 2666 MT/s for reliable operation.

Suits standard desktop upgrades.

The module is non-ECC and unbuffered, so it matches typical consumer desktop boards that accept UDIMM memory. It will not work in platforms that require error-correcting code or registered DIMMs. Buyers needing ECC functionality or registered memory should look at a different product.

Deciding spec: non-ECC unbuffered DDR4 at 2666MHz

This single attribute determines whether the stick fits the motherboard's memory controller and slot type. If the system calls for non-ECC UDIMM DDR4 2666 (PC4-21300), the module is compatible; otherwise it will not function.
