M378A1K43BB2-CRC Samsung Electro-Mechanics

The Samsung M378A1K43BB2-CRC is a high-performance 8GB DDR4 Unbuffered DIMM (UDIMM) memory module designed for mainstream desktop and workstation platforms. Organized as 1Gx64, this module provides a substantial 8-gigabyte capacity in a single rank, effectively balancing performance and cost for a wide range of computing applications. Operating within a precise voltage range of 1.14V to 1.26V, it offers optimized power efficiency. The module is built on a standard 288-pin UDIMM form factor, ensuring broad compatibility with consumer and commercial motherboards that support DDR4 memory technology.

Key Features

• High-Capacity Design: 8GB (1G x 64) organization provides ample memory for multitasking, general computing, and entry-level content creation.
• Optimized Power Profile: Operates within a 1.14V to 1.26V range, supporting JEDEC-standard and potential low-power states for improved system energy efficiency.
• Broad Platform Compatibility: Standard UDIMM-288 package ensures direct compatibility with a vast array of desktop and workstation motherboards supporting non-ECC DDR4 memory.
• Standard Compliance: Adheres to JEDEC DDR4 specifications for reliable interoperability and performance in its target applications.

Technical Specifications

• Organization: 1G x64
• Module Type: DDR4 UDIMM
• Operating Voltage (VDD): 1.14V - 1.26V
• Maximum Operating Current: 856 mA
• Pin Count: 288
• ECC Support: No
• AEC-Q100 Qualified: No

Pin Configuration and Functions

• No pin definition: As a complete memory module, individual pin functions are defined by the JEDEC DDR4 UDIMM standard. The 288-pin interface includes address, data, control, clock, and power/ground pins.

Typical Applications

• Desktop Computer Systems: Primary system memory for home, office, and gaming PCs.
• Entry-Level Workstations: Supporting memory for professional applications requiring moderate RAM capacity.
• Commercial Point-of-Sale and Kiosks: Reliable memory for fixed-function computing terminals.
• Small Form Factor PCs

Equivalent / Alternative Parts

• M378A1K43BB2-CTD (Samsung) - Same organization, capacity, and package; potential variation in speed bin or sub-timing.
• KVR26N19S8/8 (Kingston) - Equivalent 8GB DDR4 UDIMM module, based on industry-standard specifications for cross-manufacturer compatibility.

Advantages

• Proven Reliability from a Leading Manufacturer: Benefits from Samsung's vertically integrated DRAM production, ensuring consistent quality and performance.
• Cost-Effective Memory Solution: As a non-ECC, non-automotive UDIMM, it offers an optimal price-to-performance ratio for mainstream computing.
• Simplified Inventory and Sourcing: The standard JEDEC-compliant design allows for easier second-source qualification compared to proprietary modules.

Limitations

• Lacks Error Correction: Not equipped with ECC, making it unsuitable for mission-critical servers or workstations where data integrity is paramount.
• Not Rated for Harsh Environments: Not AEC-Q100 qualified, excluding it from automotive or extended temperature industrial applications.
• Fixed Capacity and Configuration: The 1Gx64 single-rank design may not be optimal for all platforms, as some systems benefit from dual-rank or different density modules for maximum performance.

Package Information

UDIMM package (standard DDR4 unbuffered dual in-line memory module form factor), 288 pins, through-hole mounting via edge connector.

Manufacturer Information

Samsung Electro-Mechanics is a core component subsidiary of the global Samsung Group, specializing in advanced electronic components. As a world-leading manufacturer of memory semiconductors, Samsung's DRAM products are renowned for their technological innovation, high volume production capability, and consistent quality, serving a vast range of consumer and computing electronics markets worldwide.

Design-in Tips

• Verify Motherboard Compatibility: Confirm the target motherboard's QVL (Qualified Vendor List) or ensure it supports DDR4 UDIMMs at the module's specified voltage and timing.
• Observe Proper Handling Protocols: Always handle the module by its edges to prevent static discharge (ESD) damage to the memory ICs and avoid touching the gold-plated contacts.
• Ensure Correct Installation: Align the module's notch with the key in the DIMM slot and apply firm, even pressure on both ends until the retention clips engage fully.
