Overview
The Samsung M378A1K43EB2-CWE is an 8GB DDR4 SDRAM memory module designed for compatible desktop computers. It uses a standard 288-pin unbuffered DIMM form factor and supports desktop platforms designed for non-ECC DDR4 memory.
With a rated data rate of 3200 MT/s, this module provides additional memory capacity for compatible computers used in office work, everyday computing, and professional desktop applications.
Memory Performance and Architecture
This module operates at a nominal voltage of 1.2V and has a rated CAS latency of CL22. Its single-rank x8 organization uses eight 1G x8 DRAM components to provide 8GB of total memory capacity.
The unbuffered architecture is intended for systems that support standard desktop UDIMM memory rather than registered server memory. Actual operating speed depends on the processor, motherboard, firmware settings, and installed memory configuration.
Compatibility
The M378A1K43EB2-CWE is intended for desktop computers with compatible 288-pin DDR4 UDIMM slots. Check the motherboard and processor specifications before purchasing to confirm supported memory capacities, data rates, and module configurations.
- Requires a compatible 288-pin DDR4 DIMM slot.
- Designed for unbuffered, non-ECC memory configurations.
- Not suitable for laptop slots that require SO-DIMM memory.
- Not a replacement for registered server memory or ECC memory when those functions are required.
Key Features
- 8GB capacity: Adds memory capacity to compatible desktop systems.
- DDR4-3200 data rate: Supports a rated transfer rate of 3200 MT/s.
- Single-rank x8 organization: Uses a 1Rx8 memory configuration.
- 288-pin UDIMM form factor: Designed for compatible desktop DDR4 memory slots.
- 1.2V operating voltage: Uses the nominal supply voltage specified for this DDR4 module.
Applications
This module can be used to expand or replace memory in compatible desktop computers, including office PCs, home computers, and workstations that support unbuffered non-ECC DDR4 memory. It is also suitable for maintenance and replacement projects where the original module specifications match.
DC Supplies Product Note
When upgrading an existing desktop, verify the motherboard's maximum supported memory speed and capacity before selecting this module. A system that supports DDR4 memory may run the module below its rated data rate, depending on processor and motherboard limitations.

Frequently Asked Questions
1. Is this module compatible with my desktop computer?
Compatibility depends on the motherboard and processor. Confirm support for 8GB DDR4 UDIMMs, the module's organization, and the required operating speed before purchasing.
2. Can I install this memory in a laptop?
No, not in a laptop designed for SO-DIMM memory. This is a full-size 288-pin desktop UDIMM.
3. Does this module support ECC?
No. This is non-ECC memory and does not provide ECC error-correction functionality.
4. Will it operate at 3200 MT/s in every compatible system?
No. Although the module is rated for 3200 MT/s, the actual operating speed depends on the processor's memory controller, motherboard support, firmware settings, and other installed modules.
5. Can I combine this module with existing RAM?
Combining modules may be possible if the system supports their capacities and configurations. Check the motherboard manufacturer's guidance and the specifications of the existing memory before mixing modules.
