SAMSUNG M393A2K43BB1-CRC 16GB DDR4 2400 RDIMM
The Samsung M393A2K43BB1-CRC is a 16GB DDR4-2400 registered ECC memory module intended for enterprise servers, data centers, virtualization hosts, and storage systems. As a JEDEC-standard RDIMM, it targets IT departments, system integrators, and resellers who need stable, buffered memory for 24/7 workloads such as virtualization and caching tiers. Note that RDIMMs must match the memory generation and type supported by your platform — DDR4 RDIMMs cannot be mixed with DDR5 or unbuffered desktop modules.
Key specifications (table)
| Parameter | Specification |

| Compliance | JEDEC DDR4 Standard |
| Applications | Enterprise Servers, Data Centers, Virtualization Platforms, Storage Systems |
Good to know
- Compatibility: server RDIMMs are not interchangeable with UDIMMs/LRDIMMs — verify your server’s qualified memory list (QVL) and ensure all installed modules are DDR4 registered modules of matching speed grade for stable channel population.
- Family positioning: this sits in Samsung’s mainstream DDR4 RDIMM line at 2400 MT/s; it is well suited to mixed virtualization and storage workloads where ECC reliability matters more than peak bandwidth.
- Buying tip: for multi-channel servers, purchase modules with identical capacity, rank configuration (2Rx8), and speed grade to keep memory channels balanced and avoid the BIOS downclocking channels to the slowest module.
For tray and reel pricing, current stock by part number and date code, and volume discounts on bulk orders, request a bulk quotation.
