Samsung 32GB DDR3 1333MHz ECC Load Reduced Server Memory — M386B4G70DM0-YH93Q

The Samsung M386B4G70DM0-YH93Q is a 32GB DDR3 ECC Load Reduced DIMM (LRDIMM) server memory module operating at 1333MHz (PC3-10600) with CAS latency CL9 and 1.35V low-voltage operating voltage. Designed for high-density DDR3 server deployments, this Quad Rank x4 LRDIMM uses a memory buffer to reduce electrical load on the memory controller — enabling higher DIMM counts per channel than standard RDIMMs while maintaining signal integrity. Error-Correcting Code (ECC) technology continuously detects and corrects single-bit memory errors in real time, ensuring data integrity in mission-critical environments. This module is ideal for maximizing total system memory capacity on DDR3 server platforms that support LRDIMM technology.

Frequently Asked Questions

What is the difference between an LRDIMM and an RDIMM?

An LRDIMM (Load Reduced DIMM) uses a memory buffer chip to isolate DRAM from the memory controller, reducing electrical load and enabling more DIMMs per channel than standard RDIMMs. This allows higher total system memory capacity at the cost of slightly higher latency. LRDIMMs and RDIMMs are not interchangeable.

What does the YH93Q qualification suffix indicate?

Samsung uses qualification suffixes to denote OEM validation, regional certification, or specific server vendor testing. YH93Q identifies this module's exact qualification tier — always cross-reference with your server vendor's memory compatibility or QVL list before purchase.

Is this module compatible with DDR4 or DDR5 servers?

No — DDR3 LRDIMMs are only compatible with DDR3 LRDIMM-capable server platforms. DDR3, DDR4, and DDR5 are not interchangeable in any configuration. Always verify your server's memory type and DIMM type requirements before ordering.

Whether you are expanding memory capacity in an existing DDR3 server infrastructure or maintaining legacy high-density deployments, the Samsung M386B4G70DM0-YH93Q delivers the 32GB DDR3 LRDIMM capacity, ECC protection, and Samsung manufacturing quality your enterprise server environment demands.
