Samsung 4GB PC3-12800 DDR3-1600MHz non-ECC Unbuffered Memory Module

The Samsung M378B5273DH0-CK0 is a 4GB DDR3-1600MHz memory module that drops straight into any desktop motherboard using a standard 240-pin DIMM slot. Running at 1.5 volts and communicating over the PC3-12800 bus, it gives older or budget-focused systems a quick boost in available memory without changing other hardware.

The module follows a non-ECC, unbuffered design, so it pairs naturally with consumer and office desktops where error-correcting features are not required. Dual rank architecture and a CAS latency of 11 help maintain stable performance during everyday tasks such as web browsing, document editing, streaming, and light gaming.

Whether you are extending a system that currently feels tight on memory or replacing a faulty stick, this Samsung module offers a simple, affordable path to smoother multitasking. Install it on its own for a modest uplift or combine it with another identical module to reach 8GB and enable dual-channel configurations where supported.
