SAMSUNG M378B5273CH0-CH9 4GB PC3-10600U DDR3 1333 1-Stick desktop RAM

4 GB DDR3 UDIMM module

This single 4 GB DDR3 UDIMM runs at 1333 MT/s and fits standard desktop DIMM slots. It suits owners of older systems that still use DDR3 memory and need a modest capacity increase. The stick is unbuffered and non-ECC, matching typical consumer motherboards.

Replaces a missing or failed stick

Use this module when a system has an empty slot or a defective 4 GB DIMM and the board supports PC3-10600 speeds. The upgrade is worthwhile only if the platform cannot accept larger modules or faster DDR3 grades. Buyers who need more than 4 GB total capacity or higher bandwidth should look elsewhere.

Limited by the DDR3 interface

The DDR3 interface tops out at the 1333 MT/s data rate this module provides. Bandwidth and latency are fixed by that standard, so performance cannot scale with newer processors or chipsets. Systems requiring greater throughput must move to a later memory generation.
