Product Overview
The Samsung M378A5244CB0-CTD is a 4GB DDR4 SDRAM memory module designed for compatible desktop computers. It operates at a data rate of 2666 MT/s and uses a 288-pin unbuffered DIMM format. This module features a single-rank x16 organization, non-ECC operation, and a nominal operating voltage of 1.2V.
Key Features
- 4GB capacity: Provides memory capacity for compatible desktop systems.
- DDR4-2666 performance: Supports a data rate of 2666 MT/s, also identified as PC4-21300.
- 288-pin UDIMM: Designed for desktop motherboards that support this memory format.
- Single-rank x16 organization: Uses a 1Rx16 module configuration.
- Non-ECC and unbuffered: Intended for compatible non-ECC desktop memory configurations.
Compatibility
This memory module is intended for desktop systems with a compatible 288-pin DDR4 UDIMM slot. Before installation, verify motherboard and processor memory support, the system's maximum supported capacity, and the supported memory speeds. The module's rated data rate does not guarantee that every system will operate at 2666 MT/s.
Typical Applications
- Compatible desktop PC memory upgrades
- Replacement for matching DDR4 UDIMM modules
- Memory expansion in supported office and general-purpose desktop systems
DC Supplies Product Note
Confirm the exact part number, M378A5244CB0-CTD, and your system's memory requirements before ordering. This is a 4GB DDR4 desktop UDIMM, not a laptop SO-DIMM or a DDR5 module. Compatibility depends on the motherboard and processor specifications.
