Samsung 16GB DDR4 2133 Mbps Memory Module

The Samsung M378A2K43BB1-CPB is a 16GB DDR4 memory module for desktop computers that accept unbuffered DIMMs with 288 pins. It runs at 2133 Mbps while drawing only 1.2 volts, delivering steady throughput without demanding extra power or added cooling.

A dual rank x8 layout helps the module handle heavier multitasking loads with minimal latency. When paired with a motherboard that supports two ranks per DIMM and two DIMMs per channel, it lets you expand total capacity for creative work, gaming libraries, and browser sessions packed with tabs.

Upgrading is straightforward: align the notch, press the module into an open slot until the latches click, and power the system back on. Office professionals will notice smoother spreadsheet navigation, creators can keep larger assets in memory, and gamers can run voice chat and streaming tools alongside their favorite titles without slowdowns.

Samsung manufactures the DRAM chips in house and subjects every module to strict quality checks, so compatibility with popular Intel and AMD desktop platforms is rarely a concern. The unbuffered design avoids the extra clock cycles that registered modules add, which can make day-to-day tasks feel snappier.

Highlights:

• 16GB DDR4 module rated at 2133 Mbps
• Operates on 1.2 volts to reduce power draw and heat
• Unbuffered DIMM design that delivers lower latency
• Dual rank x8 configuration supports demanding multitasking
• 288 pin form factor fits standard desktop motherboards
