Samsung 8GB 2RX8 PC3-14900R Memory Module

The Samsung M393B1G73QH0-CMA is an 8GB memory module based on DDR3 technology that uses registered architecture to give enterprise servers consistent, reliable performance. Built around a two-rank x8 layout, it fits standard 240-pin RDIMM slots and moves data at speeds up to 1866 megatransfers per second.

This module works at either 1.5 volts or a lower 1.35 volts, so it blends easily with mixed-voltage setups and helps reduce power draw in dense racks. A dedicated register controls clock, command, and signal timing, while an 8-bit parity path maintains error-correcting code to keep data accurate during heavy workloads.

In real-world use, the M393B1G73QH0-CMA is a practical upgrade for virtualization hosts, database servers, or any environment that handles large data sets around the clock. You can install up to two modules per channel in a 2DPC arrangement, scaling memory capacity without sacrificing stability.

Whether you are expanding a blade chassis, outfitting a new rack server, or replacing aging DIMMs, this Samsung module slots in quickly and plays well with hardware that accepts PC3-14900R memory.
