Overview
The Samsung M378A4G43AB2-CWE is a 32GB DDR4 SDRAM memory module designed for compatible desktop computers. It uses a 288-pin unbuffered DIMM form factor and provides dual-rank memory organization for systems supporting non-ECC DDR4 desktop memory.
With a rated data rate of 3200 MT/s, this module provides additional memory capacity for compatible desktop systems used in business applications, multitasking, content creation, and general computing workloads.
Memory Performance and Architecture
The module supports DDR4-3200 operation, corresponding to the PC4-25600 memory classification. It operates at a nominal voltage of 1.2V and has a CAS latency of CL22.
Its dual-rank x8 configuration uses sixteen DRAM components arranged across two ranks. The unbuffered design is intended for compatible desktop platforms rather than systems requiring registered server memory.
The actual operating speed depends on the processor's memory controller, motherboard specifications, firmware configuration, and the other installed memory modules.
Compatibility
The M378A4G43AB2-CWE is intended for desktop computers supporting 288-pin DDR4 UDIMM memory. Before installation, verify that the motherboard and processor support 32GB memory modules, the DDR4-3200 data rate, and the module's dual-rank organization.
- Requires a compatible 288-pin DDR4 DIMM slot.
- Designed for unbuffered, non-ECC memory configurations.
- Uses a dual-rank x8 organization.
- Not suitable for laptop slots designed for SO-DIMM memory.
- Not a replacement for registered server memory or ECC memory where those features are required.
Key Features
- 32GB memory capacity: Provides a substantial memory allocation in a single desktop DIMM.
- DDR4-3200 data rate: Supports a rated transfer rate of 3200 MT/s.
- Dual-rank x8 architecture: Uses a 2Rx8 memory configuration with sixteen DRAM components.
- 288-pin UDIMM form factor: Designed for compatible desktop DDR4 memory slots.
- 1.2V operation: Uses the nominal operating voltage specified for this DDR4 memory module.
Applications
This memory module can be used to expand or replace RAM in compatible desktop computers and workstations. Its 32GB capacity can support workloads involving multiple applications, large working datasets, software development, and memory-intensive productivity tasks, subject to the host system's capabilities.
DC Supplies Product Note
Before using this module in a system with existing memory, check the motherboard's supported memory population rules. A 32GB dual-rank module may have different compatibility requirements from lower-capacity single-rank modules, and mixed configurations can affect the supported operating speed.

Frequently Asked Questions
1. Is the Samsung M378A4G43AB2-CWE compatible with every DDR4 desktop?
No. Compatibility depends on the motherboard, processor, supported memory capacity, module organization, and firmware. Check the system manufacturer's memory compatibility documentation before purchasing.
2. Can I install this module in a laptop?
This is a full-size 288-pin desktop UDIMM. It is not compatible with laptop memory slots designed for smaller SO-DIMM modules.
3. Does this module support ECC?
No. This is non-ECC memory and does not provide ECC error-correction functionality. Systems that require ECC memory need a compatible module specifically designed to support it.
4. Will the memory always run at 3200 MT/s?
Not necessarily. Although the module is rated for 3200 MT/s, the actual operating speed depends on the processor, motherboard, firmware settings, and installed memory configuration.
5. Can I combine this 32GB module with existing RAM?
Combining modules may be possible if the system supports their capacities and configurations. Verify the motherboard's memory population guidelines and supported combinations before installing additional memory.
