Samsung 32GB DDR4-2666 M393A4K40CB2-CTD8Q ECC RDIMM Memory Module

The Samsung M393A4K40CB2-CTD is a 32GB DDR4 memory module created for servers that need dependable performance every hour of the day. With a speed of 2666 megatransfers per second, it keeps data flowing smoothly when virtualization, database work, or analytics place heavy demands on the system.

This module uses an ECC Registered layout that buffers clock, command, and control signals before they reach the DRAM chips. The register helps maintain signal integrity in motherboards that hold several DIMMs, while the built-in 8-bit error correction logic quietly fixes single-bit faults to prevent crashes and data corruption.

A 288-pin design and a 1.2 volt operating level follow JEDEC DDR4 standards, so installation is simple in any board that supports DDR4 ECC RDIMM memory. The dual-rank 2R x 4 architecture balances capacity and throughput, and its compatibility with x4 and x8 device organizations lets administrators populate two DIMMs per channel without sacrificing reliability.

Data centers, small business racks, and lab clusters can all benefit from this module. Add it to a VMware host to raise virtual machine density, slot it into a database server that handles critical transactions, or deploy it in an HPC node that crunches large scientific datasets. If your motherboard accepts DDR4-2666 ECC RDIMM, the Samsung M393A4K40CB2-CTD provides a straightforward path to greater memory capacity and stable operation.
