Product Description

Samsung 32GB DDR4 ECC Registered RDIMM – High-Density Module

This Samsung M386A4G40DM0-CPB is a high-density 32GB DDR4 server memory module with ECC. Featuring a 2Rx4 (Dual Rank, x4) organization and 2666MHz speed, it is engineered for modern data center servers that require maximum memory capacity and performance for virtualization, databases, and other memory-intensive workloads.

Key Specifications:

• Capacity: 32GB (High-Density)

• Type: DDR4 SDRAM with ECC

• Speed: 2666 MHz (PC4-21300R)

• Voltage: 1.2V

• Module Type: 288-pin ECC Registered DIMM (RDIMM)

• Organization: 2Rx4 (Dual Rank, x4)

• Part Number: M386A4G40DM0-CPB

Compatibility & Applications:

• Target Systems: Designed for modern high-capacity servers such as Dell PowerEdge R740/R750, HPE ProLiant DL380 Gen10, Lenovo ThinkSystem SR650, and Cisco UCS M5.

• Ideal For: Significantly increasing RAM in virtualization hosts (VMware, Hyper-V), in-memory databases (SAP HANA, Redis), high-performance computing (HPC), and business-critical application servers.

• ⚠ Critical Compatibility Note: This is a x4-based RDIMM (2Rx4). Most servers prohibit mixing x4 and x8 based modules (e.g., 1Rx8, 2Rx8) in the same system. Verify your server’s memory population rules before purchasing.
