Samsung DDR4 2133MHz UDIMM

This Samsung M378A2K43BB1-CPB module provides 16GB of DDR4 2133MHz memory for desktop systems. It uses an unbuffered, non-ECC UDIMM design with a standard 288-pin interface. The module is built with 16 FBGA 78-ball 1Gx8 DRAM components organized as 2Gx64. It is suited for standard desktop upgrades or replacements.

Fits standard desktop DDR4 slots

This module suits users upgrading a desktop that accepts DDR4 2133MHz UDIMM memory. It is not for systems requiring registered or load-reduced DIMMs. Buyers needing error-correcting code memory should look elsewhere. Laptops and small-form-factor devices using SO-DIMM slots cannot use this 288-pin module.

Speed is DDR4 2133MHz PC4 17000

The operating speed of DDR4 2133MHz (PC4 17000) is the specification that determines compatibility with your motherboard and memory controller. Verify that your platform supports this data rate before purchase. The 16GB capacity and unbuffered, non-ECC design are fixed attributes of this part.

What does the 2133MHz rating deliver inside my desktop?

The module runs at 2133 MT/s, providing PC4-17000 peak transfer rates for everyday workloads and multitasking.

Does the 288-pin DDR4 interface limit speed or compatibility?

The 288-pin unbuffered DDR4 design fits standard desktop DIMM slots and operates at the rated 2133MHz without extra configuration.
