Product Overview
The Samsung M393A2K43DB3-CWE is a 16GB DDR4 SDRAM memory module designed for compatible servers and enterprise workstations. It operates at a rated data rate of 3200 MT/s and uses a 288-pin registered DIMM (RDIMM) form factor. With ECC support, dual-rank x8 organization, and a nominal operating voltage of 1.2V, it is suitable for supported server memory configurations.
Key Features
- 16GB capacity: Provides memory expansion for compatible server platforms.
- DDR4-3200 performance: Rated at 3200 MT/s, with a PC4-25600 memory classification.
- ECC support: Provides error-correction capability on supported systems.
- Registered DIMM design: Uses registered memory architecture for compatible server platforms.
- Dual-rank x8 organization: Uses a 2Rx8 configuration with 1.2V nominal operating voltage.
Compatibility
This module is designed for servers and workstations that support DDR4 ECC registered DIMMs. Registered DIMMs are not interchangeable with standard unbuffered desktop memory, and RDIMMs generally cannot be mixed with load-reduced DIMMs (LRDIMMs). Check the system manufacturer's documentation for supported memory types, capacity limits, processor requirements, and memory population rules.
Typical Applications
- Enterprise server memory upgrades
- Replacement of matching 16GB DDR4 RDIMM modules
- Compatible workstation memory configurations
- Business computing and general server workloads
DC Supplies Product Note
Confirm the exact part number, M393A2K43DB3-CWE, and check your server's compatibility list before ordering. This is ECC registered server memory, not a standard desktop UDIMM or laptop SO-DIMM. The actual operating speed depends on the processor, motherboard, and installed memory configuration.

Frequently Asked Questions
What is the capacity of this Samsung memory module?
The M393A2K43DB3-CWE has a capacity of 16GB.
What is its rated memory speed?
It is rated for DDR4-3200, or 3200 MT/s. The actual operating speed depends on the host system and memory configuration.
Does this module support ECC?
Yes. It is an ECC memory module designed for compatible systems that support registered error-correcting memory.
Can I install this RAM in a standard desktop PC?
Generally, no. Most consumer desktop motherboards require unbuffered UDIMMs rather than registered RDIMMs. Verify your motherboard specifications before purchasing.
Can RDIMM and LRDIMM modules be mixed?
RDIMMs and LRDIMMs generally cannot be mixed in the same system. Follow the server manufacturer's memory configuration guidelines.
